It was. decided that the best way to this was to mathematically model the river reach below the proposed damsites. With a model that is calibrated and verified to mathematically interpret river hydraulics, specific river reaches can be investigated and results delivered in a timely manner to interested parties. The Corps of Engineers HEC-2 model has been used for this purpose. The model was calibrated under pre-project flow conditions and is capable of simulating river hydraulics under proposed post-project flows. Model results include water surface elevations and hydraulic data which are used for several companion studies such as: 0 0 0 0 0 0 0 Systems Operations Studies Ice Cover Process Model River Morphology Studies Flood Studies Fisheries Studies Vegetation Studies Navigation Studies 1.2 -Report Contents This report includes a summary in Section 2 of the analyses performed and results obtained in both the hydraulic and the ice studies. The scope of work of each portion is discussed in Section 3, along with the type of field data collected for each. Section 4 details the hydraulic analyses, describing the river system and the study reaches, the study approach used, the method for selecting Manning's n values, and the computation results. The summary printout tables give values for all the pertinent hydraulic parameters at all surveyed river cross-sections. The ice processes analyses are described in Section 5, and Section 6 gives the references used for the analysis and report. Attachments provide stage-discharge rating curves at all the water level observation sites (Attachment A) and cross-section plots for both study reaches with computed water surface elevations marked (Attachments B and C). s9/h 1 - 1 - i,...._ 2 -SUMMARY 2.1 -Open Water Studies The open water hydraulic analysis was performed with the HEC-2 Water Surface Profile computer model of the U.S. Army Corps of Engineers. Two river reaches were analyzed: (1) the Upper Susitna Study Reach from Deadman Creek down to Devil Creek, containing the Watana damsite; and (2) the Middle Susitna Study Reach from the outlet of Devil Canyon down to the Susitna- Chulitna confluence. Four river discharges were used to calibrate the model for each study reach, and two additional flows were used to verify the calibration. The upper reach flows ranged from 8100 to 46,400 cfs (at the Watana streamgage). The range of flow used for computations on the Middle Susitna was from 9700 to 52,000 cfs (observed at the Gold Creek gage). Channel flows upstream and downstream of the gaging ~ites were adjusted up or down based on drainage area. The upper limit in each case closely coincided with the mean annual peak flow. .This level, represented by bank-full stage, was the upper boundary on the scope of the present study. The Susitna River is heavily laden with sediment, and both study reaches have numerous islands, gravel bars, and split-channel conditions . This is more prevalent in the Middle Susitna reach, and two flow regimes were analyzed there -one for low flows and one for high flows.· The low-flow regime was characterized by restriction of flow from certain side channels which were blocked off at their upstream ends by a gravel 11 berm 11 • The cutoff flow between high and low was estimated to be 20,000 cfs. The computer program uses the Manning equation for its computations. The Manning n, or roughness coefficient, was specified as an average value for the channel portion of ·each cross-section. Initial values were estimated by preliminary hydraulic calculations with observed flow conditions and adjusted based on local bed material, vegetation, channel geometry, and flow level. The range in coefficients for the 11 base11 flows (opening parenthesis) (8, 100 cfs in the upper reach and 9700 cfs in the middle Susitna) was from 0.040 to 0.060 and from 0.030 to 0.055 in the upper and middle reaches, respectively. N values at all sections were reduced for higher flows, in accordance with the observed trend. The final results from the water surface computations are presented in two forms: (1) the summary printout tables in Section 4, and (2) marked water surface elevations on plots of each cross-section· in Attachments B and C to the report. s14/k 2 -1 Some prudence is required in interpreting the output results from the analysis. Uncertainties in field measurements of hydrographic and topographic parameters and limitations of the HEC-2 model itself limit the precision of the final answers. The computed water surface elevations, however, are expected to be accurate to within 0.5 foot of the true elevations in most cases and to within 1.0 foot at almost every cros.s-section (except as discussed below). Potential problem areas where observed and computed water levels may not agree closely are at points widely separated from the observation sites and also at islands, sloughs, side channels, and river bends._ The model, of necessity 1 assumes a uniform water surface all the way across the cross-section 1 a situation not always present under natural conditions. Further refinement of the model is possible, concentrating primarily on definition of water surface elevations in side channel areas. Additional field surveys would be necessary to determine the channel goemetry at the upper ends of the cut-off channels and to more closely identify the discharge or stage at which vario1,.1s channels of importance "open up 11 to main-channel flow. 2.2 -Ice Studies The purpose of the ice studies was to simulate the river ice regime under natural and post-project conditions in the reach between Talkeetna and the proposed damsites. Acres• in-house computer simulation models were used in the studies. Results of the open water analyses, as de.scribed in Section 2.1, and field ice observation data (see "Ice Observations", R&M, 1981b) were input to the model for calibration purposes. The analyses indicate that ice regime in the river reach above Talkeetna will be significantly altered after the projects are commissioned. When Watana development is on-line, it· is expected that the ice cover formation above Talkeetna will be delayed by 2 to 3 weeks to the middle of December and will progress about 15 miles (to about LRX-15) by the end of January. It is unlikely that any significant ice cover will exist above this section under average weather conditions. With both Watana and Devil Canyon Dams commissioned, it appears that little ice cover will form above Talkeetna except close to the Chulitna confluence in late January. Ice formation in the reservoirs will commence around the middle of October, as under natural conditions in the river, and reach a stable level by the end of January. It has not been possible to estimate, with any accuracy, the post-project ice regime in the river below the Talkeetna confluence. Field observations of the freeze-up phenomena in 1980 s14/k 2 - 2 - - ...... """'!.·. -· - - - - . """' - ·- - - indicate that about 80 percent of the frazil ice below the confluence is generated by the Susitna River. With both the projects in place, there is likely to be a significant drop in the amount of frazil ice generated in the Susitna River above the confluence, thus delaying the ice cover formation in the lower river. Under natural conditions, the river ice breakup starts around mid-May with increases in air temperature and river discharge. Since the Susitna is a south-flowing river, breakup usually starts close to the river mouth and works its way up the river, thus reducing serious ice jamming in the river. The breakup is generally a mechanical process involving largely the physical movement of ice downstream with increased discharge. Partial thermal decay accompanies this process to accelerate breakup. However, under post-project conditions, the in-place thermal decay of the ice cover, at least above Talkeetna, is expected by the end of March. The effect of warmer waters from the reservoirs, coupled with higher air temperatures, would cause almost in-place melting of ice in the main stem a few weeks before the natu raJ breakup in the Talkeetna, the Chulitna, and the lower tributaries. More detaHed river observation, cross-section surveys, and data collection in the lower river will be needed to model the lower river ice processes and to assess the effects of the projects in the reach. s14/k 2 - 3 - 3 -SCOPE OF STUDY This report presents the results of hydraulic and ice studies performed on two reaches of the Susitna River. The two study reaches were (1) the 25-mile reach between Deadman Creek and Devil Creek, 90 percent of which is downstream of the proposed Watana Damsite, and (2) the 52-mile reach between Devil Canyon and Talkeetna, all of which is below the proposed Devil Canyon Damsite. They are referred to in this report as (1) the Upper Susitna Study Reach (or Upper Susitna), and (2) the Middle Susitna Study Reach (or Middle Susitna), respectively (11 Lower Susitna11 generally refers to the river downstream of Talkeetna). Analysis consisted essentially of collecting field data, of operating a computer water surface profile model, and of operating a computer ice cover process model. 3.1 -Related Field Data Collection Field data required for hydraulic analyses were topographic and hydrographic information at river cross-sections, water-surface elevations at selected sites for a range of discharges, and qualitative information on vegetation and bed material. The ice analyses utilized the cross-section data and also required air temperature and water temperature data; timing, location, and extent of ice accumulations and bridging during freezeup and breakup; and site-specific hydraulic data from freezeup and breakup. Site-specific hydraulic data consisted of open-water width, surface velocity, water surface elevation, rate of rise of the water surface, and ice pan thickness. Cross-section surveys on the Upper Susitna were made in March 1981 by drilling holes through the ice cover. The lower reach (i.e. Middle Susitna) was surveyed' prior to and during freezeup in the fall of 1980. More detailed description of the field methods and the summarized survey data are presented in the report, 11 Hydrographic Surveys 11 (R&M, 1981a). Water elevation data were collected at crest-stage recorder . sites periodically through the study period. The ice observations from fall 1980, winter 1980-81, and spring 1981 are contained in the report, 11 1ce Observations 11 ( R&M, 198'1b). Subsequent ice observations are to be reported in an addendum to the 1981 report. 3. 2 -Open Water Analyses The hydraulic analyses were done using the HEC-2 water surface profile model developed by the Hydrologic Engineering Center of the U.S. Army Corps of Enigneers. Model calibration and verification were made with data collected at crest-stage and continuous recorders located in the study reaches. Three s13/a 3 - 1 crest-stage recorders and a continuous streamgage were established on the Upper Susitna. Six crest gages were installed on the Middle Susitna, and the USGS had a continuous· recorder at Gold Creek. Stage levels were measured at each site in the two reaches for several river discharges. Four flows were used to calibrate the models, and two additional ones were used to verify it, making a total of six different flows for each study reach. The scope of the study was limited to flows at or below bank-full conditions. Thus, no overbank floods were analyzed. Flood frequency analysis (R&M, 1981d) indicated that the mean annual flood for Gold Creek was 49,500 cfs. Observed peaks in the summers of 1980 and 1981 were just slightly higher than the mean annual peak flow. Both happened to roughly coincide with top-of-bank flows., so the this flow condition was well defined. Two versions of the model were necessary to adequately describe the river behavior in the Middle Susitna reach. This was because two regimes were apparent, a low-flow regime and a high-flow regime. Examination of aerial photos and field conditions revealed a number of side channels and sloughs that received substantial river flow at high discharges but negligible flow below a certain threshold value. Thus, a high-flow version was set up wherein river flow was permitted in these channels, and another, low-flow version was set up assuming no flow there. The threshold was estimated at 20,000 cfs for the Middle Susitna. 3.3 -Ice Process Analyses Acres• in-house computer models -were used to analyze the ice regime of the two river reaches above Talkeetna up to the damsites under natural and post-project conditions using field data collected during the river freezeup/breakup in 1980-81 and open water calculations as discussed in Section 3. 2. Estimates of ice cover formation and development in the reservoirs were made using standard heat balance equations. Jt has not been possible to analyze ice regime below the Talkeetna confluence under natural or post-project conditions due to lack of field data and river cross sections. However, an attempt has been made to estimate qualitatively the effect of the proposed projects on the ice regime of the river in the lower reach. Salient details of the analyses are presented in Section 5. s13/a 3 - 2 ....... - -· ~J - - •• f.'.'lllZ1 'F 4-HYDRAULIC ANALYSES The hydraulic analyses involved assessment of river hydraulic data collected during the study period and computation of water surface profiles in two study reaches for a range of discharges. This portion of the report describes the analyses performed and the results obtained. It is organized to first give a brief description of the Susitna River system and the two study reaches, followed by discussion of the study approach and detailed information on development of the roughness coefficients used in the computer model. Finally, Section 4.4 discusses the results. , 4.1 -Description of River System 4.1.1 General s3/b The Susitna River drainage basin is the sixth largest system in Alaska. From the terminus of Susitna Glacier to its mouth in Cook Inlet, the Susitna River flows 320 miles and drains 19,600 square miles. Major tributaries include the Talkeetna, Chulitna, and Yentna Rivers. Plate 1 in the back folder shows the river location and regional topography for the lower 230 miles. River cross-section locations are shown in greater detail on Figure 4.1. Tributaries in the northern portions of the basin originate in the glaciers of the eastern Alaska Range. The East and West Forks of the Susitna and the Maclaren River join the mainstem Susitna River above river mile 260 and contribute roughly 38 percent of the average annual streamflow at Gold Creek. Streamflow is characterized by moderate to high flows between May and September and low flows from October to April. High summer discharges result from snowmelt, rainfall, and glacial melt. Winter flows consist almost entirely of groundwater inflow. Freeze-up starts in the higher regions in early October, and most of the river is ice-free by early to mid-May. Below the glaciers, the braided channel traverses a high plateau consisting of aggraded alluvial sediment and then meanders south for several miles to the Oshetna River confluence. There it takes a sharp turn west and flows though a steeply cut, degrading channel down to Gold Creek. The Watana and Devil Canyon damsites are both located in this latter reach. Below Gold Creek, the river follows a fairly straight course-that alternates between single and split channels until joined by the Chulitna River just above Talkeetna. Joined shortly thereafter by the 4 - 1 Talkeetna River, the Lower Susitna flows on a lower gradient than the upper river. It flows primarily through widely braided channels over its last 97 miles to Cook Inlet. Vegetation i'n the basin is predominately muskeg in poorly-drained valley bottom soils, white spruce and grasses in well-drained upland soils, and alpine tundra in steep, rocky soils above timberline. 4.1.2 Upper Susitna Study Reach The reach of river from Deadman Creek, 2 miles above the Watana Damsite, to Devil Creek, 23 miles below the damsite, is charact~rized by a narrow, steep-walled canyon and a moderately steep overall river gradient (12.1 feet/mile). Figure 4. 2 shows the profile of the thalweg through the study reach, and Table 4.1 gives the river mile and thalweg elevation for each cross-section. There are generally narrow floodplains and a few vegetated islands within the reach. The river width varies from 200 to 300 feet at the narrowest to 1000 to 2000 feet at several islands. One particularly steep local reach just above the damsite has a channel gradient of 48 feet per mile over its half-mile length. This reach, between cross-sections 103 and 104, is quite broad, in addition to being steep. The depth of flow is comparatively shallow, and standing waves are common in the vicinity. Flow is thus close to critical much of the time. 4.1.3 Middle Susitna Study Reach s3/b After emerging from Devil Canyon one mile below the Devil Canyon Damsite, the Susitna Rive·r broadens somewhat but is. still essentially confined to a canyon as far down as Gold Creek, 13.5 miles downstream. Below Gold Creek, the valley widens, bounded still between high hills on each side. River width is less than 300 feet in some sections at the upper end, and it expands to almost 3000 feet wide n.ear the confluence with the Chulitna. Quite a number of islands and gravel bars exist throughout the reach. Flow alternates between a single channel and split channels through its 52-mile extent. The bed profile of the entire reach is plotted in Figure 4.3, with the pertinent data tabulated in Table 4.2. 4 - 2 - - - '- - - . """ - - - - A ten-mile river reach between Devil Creek and about a mile below the Devil Canyon damsite could not be surveyed due to steep gradients and significant rapids. During the winter of 1980-81, however, a longitudinal river survey through Devil Canyon from upstream of the damsite for a distance of 8400 feet was completed. Salient results of the survey have been incorporated in the analyses presented below. 4.2 -Approach to Open Water Analyses The primary approach of the hydraulic analyses was to use the HEC-2 Water Surface Profiles computer model to compute water surface elevations and hydraulic parameters at numerous points of interest through a range of pre-project and expected post-project discharges. The H EC-2 computer model was developed by the U.S. Army Corps of Engineers Hydrologic Engineering Center (HEC). The standard step method is used to compute water surface profiles, using the Bernoulli Theorem for total energy at a cross-section and the Manning equation for friction head loss between river cross-sections. The program is widely used in hydraulic engineering studies. A detailed description is not provided here. If desired, details of the program may be obtained from the program users manual. The program version of November 1976 (updated April 1980) was used for the current study. Surveying of the river cross-sections comprised the major data- collection effort. The Upper Susitna Study Reach had 23 surveyed cross-sections over 25 miles. A total of 68 cross-sections was surveyed on the Middle Susitna Study Reach. As two of these were below the Susitna-Chu litna confluence and hence outside the scope of this analysis, only 66 cross-sections were used in the water surface profile computations. Periodic measurements of water surface elevations were made at crest gage and streamgage sites. These data were used in the calibration and verification of the computer model for both study reaches. The Manning roughness coefficient was an important input parameter to define at each river cross-section. Values used herein were selected based on observed hydraulic conditions (i.e. known water surface elevations at various discharges), and adjusted with consideration for bed mate'rial, vegetation, channel geometry, and other factors. An inverse relationship of 11 n 11 value with discharge was observed and incorporated into the modeling process. The procedure adopted is described in Section 4.3. s13/b 4 - 3 River lengths between cross-sections and general bank features were determined from aerial photographs and enlarged topographic maps. Maps at scales of 1 11 = 400' and 1 11 = 200' were used on the upper reach, which encompasses channel areas that will be inundated by the proposed reservoirs. Photos enlarged to a scale of 1., = 500' were used for the Middle Susitna. The model was calibrated at four separate discharges for each study reach. These calibration flows ranged from 8,100 to 46,400 cfs at Watana for the upper reach and from 9, 700 to 52,000 cfs at Gold Creek on the Middle Susitna. The model parameters were adjusted slightly as necessary to obtain agreement between the observed and computed stages within acceptable limits. The criterion for acceptability was deviation of not more than 0.5 feet. Agreert;~ent of the computed and observed water surface elevations to within this limit was sought and attained in most cases. The calibrated model was verified for each reach with two additional stream discharges. Flows used in the computations were adjusted above and below the gage sites, based on drainage area, to account for tributary inflow. The flows used for each sub-reach are listed in Tables 4.3 and 4.4. The HEC-2 program provides an excellent tool for computing water surface profiles in open-channel flow conditions. However, as does any model, it makes certain assumptions to facilitate calculation. In order to best interpret the results of the analysis, the assumptions and limitations should be understood. A few of these relevant to the current study reaches are briefly discussed below. First, the program assumes a uniform, level water surface across a given cross-section. While this is necessary to perform the analysis within reasonable computation time and cost, it is not always a true condition in the river itself. Especially at river bends, there may be quite a disparity in water level from one side of the cross-section to the other. The difference depends on river width, velocity, and radius of bend. Also, in the case of multiple channels at a cross-section, each channel may realistically have a slightly different water surface elevation, as illustrated in Tables 4.5 and 4. 6. The model, however, assumes it to be uniform across. Thus, care should be taken in interpreting the computed results in channel bends and and multiple channels. Another concern in certain portions of both study reaches was occasional overbank areas that were at lower elevations than the bank or, in some cases, below the bed of the main channel itself. Many of these areas were not hydraulically connected to the channel at lower discharges, if at all, so they were not included in the flow computations. In such situations, 11 ground levees 11 were s3/b 4 - 4 - - -· - - -. - - - -· '~. ..... - -- - used on the appropriate bank. Ground levees are imaginary levees with their tops at ground level to confine the flow to the channel until the levee (bank) is overtopped. Once the bank is overtopped, however, the model assumes complete hydraulic connection of the low area with the channel .. It was not always appropriate to permit full flow in all the lower areas, so in some cases the 11 1evee11 was left in place even at higher flow. Also, as noted above, some side channels were effectively blocked off at low flows by upstream 11 berms, 11 which were overtopped at higher flows. Definition of this condition required the use of the two models for each study reach, one permitting flow in the side channels and the other restricting it to the main channel . One final point regards the velocity computed by the model at each cross-section. This value is the mean flow velocity, averaged across the entire flow area. Field observations would most likely indicate faster flow in the center of the channel at the water surface and slower velocities at all the boundaries, but the mean is useful as an indicator of magnitude and for comparisons between cross-sections. Analysis results include water surface elevations and other hydraulic parameters at each of the cross-sections for both study reaches. No bridge or culvert analyses were required since the only bridge in either of the study reaches, the Alaska Railroad bridge at Gold Creek, was far above the bank-full level. 4.3 -Development of Roughness Coefficients The computer program HEC-2 uses the Standard Step Method described by Chow (1959) to compute the water surface profile of a river where the discharge, geometry, and channel roughness are known or can be assumed. The model uses Bernoulli's Theorem for the total energy at each cross-section and the Manning formula for the friction head loss between cross-sections. Discharges can be defined fairly well either by calculation or by direct measurement. Cross-section geometry and distances between cross-sections can similarly· be determined quite ctosely by field surveys and measurements on aerial photos. However, estimation of channel roughness coefficients (Manniflg 1s 11 n 11 ) cannot be done by direct measurement. Engineering judgment must be applied and estimates made based on past experience. Manning•s roughness coefficient varies with type and amount of vegetation encountered by the flow, relative size of bed material, channel shape, degree of meandering, and river stage, so the HEC-2 program permits definition of the 11 n 11 values in any of three different manners. Each of these was used at one time or another in the Susitna Project hydraulic analysis; their use is described in the following three sections. s3/b 4 - 5 The Middle Susitna study reach had more data readily available at the start of the hydraulic analysis. Thus, it was selected as the initial reach. Roughness coefficients were developed for the Middle Susitna reach, then experience from that analysis was used to estimate the n values in the Upper Susitna reach. (a) Variation of Manning•s n with Stage s3/b When preliminary hydraulic computations were performed on several reaches of the Susitna River (Giessel, 1981), substantial variation of n value with stage (or discharge) was indicated. Over a range in flow from 3,000 cubic feet per second (cfs) up to 34,000 cfs in the vicinity of Gold Creek, Marning•s n varied from 0.090 down to 0.035. The n is higher at low flaws because the water depth decreases relative to the size of the bed material, increasing the effects of channel roughness. The H EC-2 program allows input of n-vs. -stage data through the use of NV data input cards (HEC, 1976), in which a rating table is specified and effective roughness coefficients given for the corresponding water surface elevations at each cross-section. However, the results from HEC-2 were to be used to help verify. the ICESIM ice simulation model, which does nat have prov1s1ans far directly varying Manning's n with stage. Consequently 1 changes in n values with stage had to be made either by an adjustment coefficient or by directly changing n values at different flaw stages,· although several runs of HEC-2 were made initially to assess the potential of using the NV cards. Problems were encountered at several crass-sections with the assumed water surface elevations falling outside the range of elevations on the NV cards. In view of the need to have comparable data bases for both HEC-2 and ICESIM, the use of NV cards was nat pursued further. However, the analysis of n-vs. -stage is pertinent to the final Manning n values, and is presented below. N Value Determination The first step in the definition of n values was calculation of hydraulic parameters at certain cross-sections where water-surface elevations (W. S. E.) had been observed. The hydraulic parameters of area 1 wetted perimeter, and hydraulic radius were computed from the surveyed cross-section geometry and known W. S. E. at each of the water-observation sites listed in Table 4. 7 (the sites for the Upper Susitna are listed in Table 4. 8). A program prepared for the HP-25 hand-held calculator (Croley, 1977) was 4 - 6 -' - .... - ,_ - r ' s13/b used for the computations. Mean daily streamflows at Gold Creek for the dates of observation were obtained from the USGS rating table or from USGS records and assumed roughly equal to the flow at each of the crest gage sites (some error was expected with this assumption, but analysis indicated it would probably be only about 6% high at the upper end -Portage Creek -and about 3% low at the Susitna-Chulitna confluence). The friction slope at the cross-section was assumed approximately equal to the average bed slope over the reach from the next-upstream cross- section to the next-downstream cross-section (this assumption is adequate as a first approximation but it is less valid at high flows, with the friction slope increasing rapidly. Also, some problems were believed introduced by the presence of adverse bed slopes at a few of the cross-sections). Then, using an inverted form of the Manning equation: n = 1.49 AR 213 \ s where: Q n = A= R = s = Q= Manning roughness coefficient, cross-sectional area, hudraulic radius, friction slope, and discharge, n values were computed for each flow and correspond- ing observed W .S. E. The results for a sample cross- section ( LRX-35) are shown in Table 4. 9. The computed n values were plotted against corresponding flows for comparison. Very consistent variation was noted for four of the six cross-sections plotted, which can be seen in Figure 4.4. LRX-9 had higher computed n values than did the others. LRX-4 has several islands and channels, and consequently probably has a poorly-defined stage-discharge relationship, especially for stages observed on the far left bank (where the crest gage site is located). For the four consistent plots, however, an "average" curve was drawn in, and a preliminary relationship of n vs. Q established. A comparison was then made at the remaining cross-sections, where only limited water surface data were available. All cross-sections had at least one observed water surface elevation, which was on the date they were surveyed. Elevation differences between adjacent cross-sections were noted if they 4 - 7 were surveyed on the same day or at nearly the same flow. These differences were compared with elevation differences obtained with a slope-times-distance computation using average bed slope and channel reach length, ·and the two differences were averaged. This gave a method for 11 stepping 11 the estimated water surface elevation from the known points at the crest gage sites to each of the other cross-sections. These 11 constant differences" were then used to obtain preliminary water surface elevations to relate to flow and n value. · Five flows were selected from Figure 4. 4, from 3000 cfs to 50,000 cfs with corresponding n 1s ranging from .093 to . 028 determined from the uaverage 11 curve. These five n value;:; and stages were then used as input to the HEC-2 program, and the model was operated for the whole reach. (b) Variation of Manning 1 s n with Horizontal Stations s3/b The NH card format in the HEC-2 program input permits identification of n value changes between any stations in the cross-section. The program then computes the conveyance of each wetted subsection, based on the subsection 1s flow area, wetted perimeter, and specified roughness. As many as 20 different subsections may be identified for designation of n value at each cross-section. Basic criteria for adoption of the n values consisted of two different methods, one for the channel portion and one for the overbank portion of the cross-section. Coefficients for the channel portions of the cross-sections were determined by comparison with values obtained in the n-versus-stage analysis. The value printed out in the H EC-2 summary for each cross-section was used as a guide. Again, weight was given to variation of effective roughness with stage, so high values were assigned to a short portion of the cross-section at the bottom of the channel, intermediate values to the major extent of the channel just above that, and relatively low values to the tap portions of the channel on each side. The intent was that the effective n for the cross-section would be high at low flows and would decrease as the flow increased, as had been observed previously. The criteria developed for the overbank portions of the cross-sections are shown in Table 4. 10. These were patterned after a method presented in Chow (1959, p. 106). 4 - 8 - - - - - - - -·. - (c) - s3/b The roughness coefficients were thus assigned to the channel portions of the cross-sections. After trying the new values on a short reach 1 the whole study reach was attempted. The discharge used for the early calibration runs was 9700 cfs, considerably less than bankfull 1 so little attention was given to careful definition of the ove·rbank values at this point. A nominal value of 0.080 was arbitrarily assigned to all the areas outside the riverbanks. Problems encountered with the horizontal definition of the n values were essentially related to the ability to accurately define the roughness conditions in the channel portion. Having to specify three widely-varied values within the channel at each cross-section was somewhat time-consuming. In addition, the 11 effective11 n value obtained could not be checked until the program had been run (since it depended on the relative extent of each roughness inundated). Even then, there did not always appear to be a correlation between the numbers input and the value computed for the effective channel n. Also, the level of detail necessary to define the various n•s within the cross-section geometry did not seem to be justified. As has been mentioned, special care was not taken with the overbank areas, but it was taken with the channel areas in assigning n values. Care also had to be given to making sure the stationing was changed accordingly on the NH cards whenever it was changed on the X1 or GR cards (e.g. if bank definitions were changed or if the cross-section shape were modified). tn essence, since an option existed that permitted simpler specification of the channel n values, and since this option appeared to demonstrate better control over the effective channel n values obtained, this option was pursued. This is described in the following section. Definition of Manning•s n by Cross-Section The final method selected for specifying n values was the simplest, that of entering the values on the NC cards alone. This consisted of defining three numbers at each cross-section: one for the left overbank area, one for the right overbank, and one for the channel portion. The program considers the 11 channel 11 to be all that area between the defined left and right banks,. so aH flow within these limits will use the channel n for its computations. If the locations of the banks are changed for some reason, the n value corresponding to the channel will still be used for the channel portion (i.e. between the two new bank locations). Also, if subsequent runs are desired \to have a uniform 4 - 9 s3/b percentage increase or decrease in roughness coefficients, this is easily changing a single input parameter. Determination of n Values all the channel accomplished by The first cut at the channel n values was based on the results from the n-versus-stage analyses. For the first trial run at the 9,700-cfs flow level, an intermediate value of n = .050 was used for the whole study reach. This caused the computed water surface elevations to significantly rise above earlier runs and also above observed levels. Subsequent runs were tried .with lower n values to observe the effect on the computed elevations. An improvement was noted, and the modePs sensitivity to n value changes was roughly gaged. One noteworthy exception to the NC-card designation of n values was at cross-section LRX-25. This section is relatively wide, about 2,500 feet, and has as many as ten different flow channels at certain flow levels.· The primary channels are the ones on the far left and the far right of the cross-section, with little effective flow in-between. The nature of the HEC-2 program is such that all the channels are filled up with flow from the bottom. Channels outside the main channel can be excluded by specifiying artificial encroachments, but this cannot easHy be done for ineffective flow areas within the main channel. The technique used was assignment of a very high n value to these areas, which permitted water there but allowed for almost no conveyance. This designation was made by using NH cards at LRX-25. All other cross-sections used the NC card format. Adjustments to n Values Refinements were made to the initial estimates of Manning's n's based on several criteria. These criteria included bed material size, river sinuosity, presence of and type of vegetation, existence of multiple channels, and level of discharge. The bed material size was evaluated systematically at most of the river cross-sections by the 11 Grid-by- Number11 technique described by Kellerhals and Bray (1971). Preliminary bed materia·! distributions were obtained in the analysis, and are presented in 4 -10 - - - -. - - - - - - . - ···~ - - ·s3/b Table 4.11. The complete application and results from the analysis are described in 11 Hydrographic Surveys 11 ( R&M, 1981a). Limerinos (1970) investigated the existence of a relationship between Manning 1s n and bed material particle -size in several rivers of varied size in California. A definite correlation was observed in the study, relating weighted intermediate particle diameter (d ) and hydraulic radius (R) to Mannings 1 s n by the eqt1ation n = .90 + 2.0 log (R/dw) .0926R 1 /S To get an idea of the magnitude of n to be expected on the Middle Susitna study reach, the Limerinos formula was applied to the bed particle sizes from Table 4.11. Hydraulic radii were calculated from cross-section data using observed water surface elevations at crest gage sites. Results are shown in Table 4. 12. Items worthy of note are that the computed n values are quite insensitive to changes in flow and also that the values are all consistently in the • 030 -. 040 range. These numbers were used as a guide __ in judging the 11 proper 11 value for Manning•s n over the reach. It should be noted that these figures could probably be considered to be at the low-end of the roughness coefficient range since the analysis essentially assumed no effects from other factors, which would all tend to increase the apparent roughness. Several other factors were considered in making assignments of n value for the various sub-reaches in the study reach. The sinuosity of the river in the local area, the presence and type of vegetation in the flow area, and the existence of islands and multiple channels at or between cross-sections all contributed to the n value determinations. Generally, existence of these conditions led · to an n value increase above the base value in a sub-reach. A final factor which ultimately had a large apparent effect on the channel roughness in a reach or at a cross-section was the discharge level. As was indicated somewhat in Table 4.12, there is a decrease in n value as the flow increases. This trend had been generally observed in the original bed roughness study (Limerinos, 1970). It is also documented in a British report on several streams of various sizes (Sargent, 4 -11 s3/b 1980). . At one site in Sargent•s study, the computed n value increased from . 026 to . 044 when the flow dropped from 3,250 to 500 cfs, a percentage increase in n of over 65%. Thus, it was felt in the present study that a decrease in n value as the flow increased would be justified and appropriate. The four flow levels used for calibration of the model were 9, 700; 17 ,000; 34,500; and 52,000 cfs. As has been noted above, two versions of the H EC-2 modet were operated on the study reach -one for flows below 20,000 cfs and one for flows above 20,000. This level was significant because it marked the estimated threshold for the river flowing into selected side channels and sloughs, which was an important part of the analysis. Most of the preliminary calibration runs were done with the 9, 700-cfs flow, so a feeling was gained for the high-end . n values in the study reach. When the next-higher calibration flow (17 ,000 cfs) was run, use of the same n values produced computed water surface elevations that were above the observed ones at almost all the observation sites (th.e one exception was LRX-28, where the reliability of the stage-discharge rating curve was highly questionable). A reduction in all the n values of 10%, however, bought all the computed water surface levels very · close to the observed levels. In calibration of the high-flow version of the model, the two flows tested were 34,500 and 52,000 cfs. A reduction of 10% in n value was made in going from 17,000 to 34,500 cfs, and good matches were obtained at all the observation sites. Above 34,500 cfs, the channel n value was assumed relatively constant and was not decreased further. The n value for · 34,500 cfs was used with the 52, 000-cfs flow, again with good results at all the observation sites. Following the four calibration flows used with the program, two verification runs were made, one with each regime. The low-flow version was run with 13,400 cfs, and n values used were 5% less than those at 9, 700 cfs. The high-flow version was run with 23,400 cfs, with the same n values as were used at 17, 000 cfs. Good resu Its were seen in both runs . The final n values assumed are presented in Table 4.13. Only the values for 9, 700 cfs are given since other flow levels are uniform factors times these numbers. 4 -12 - - - -· -· - - ·- ,_ - ·- - (d) (e) Upper Susitna Study Reach Starting values for the upper reach roughness coefficients were estimated from experience with the lower reach. Definition was made by cross-section. Values from cross- sections with comparable bed material and geometry were applied and modified as necessary. Effects of islands and bends were also considered. The final assumed n values are shown in Table 4. 14., for the base flow of 8,100 cfs. Factors are also given for the adjustments used at high flows. Summary The initial Manning 1 s n values were estimated by computing them from the Manning equation, using observed water surface information at each of six different cross-sections in the Middle Susitna. The definition of Manning•s n as a function of stage at a cross-section was attempted but was abandoned because of operational problems and incompat- ibility with the ice processes model. Assignment of n values by horizontal stations at the cross-section was also used for a time but it was determined to be time-consuming 1 to require considerab~e cross- referencing of the stationing 1 and to be more refined than necessary. Thus, the method finally selected and utilized was that of n value designation by cross-section. Actually, several consecutive cross-sections were felt to exhibit similar roughness characteristics, so the same coefficient was used within whole sub-reaches. The substantial variation of n value with river discharge was noted and applied by reducing the coefficient for higher flows. 4. 4 -Results (a) s3/b Upper Susitna Study Reach The HEC-2 model was calibrated with Watana discharges of 8,100; 17,200i 30,700; and 46,400 cfs. The continuous gage two miles below the Watana damsite was used as the standard for defining flow levels· on dates of water level observations, but adjustments were made based primarily on drainage area above and below the gage vicinity. The mainstem flow was reduced above the Deadman Creek confluence and increased below the Tsusena Creek and Fog Creek confluences, all the major tributaries in the study reach. Flows used for each of the sub-reaches are given 4 -13 (b) s3/b in Table 4.3. It should be noted that flows given in the computer printout do not precisely agree with all of these since a factor was used to change flow from one reach to the next and from one run to the next and the table values are round numbers. The model was verified with streamflows of 26,700 and 42,200 cfs. Comparison of the six computed and corresponding observed water surface elevations at the crest gage and stream gage sites is given in Table 4.15. Stage-discharge rating curves (based on observations) are given in Attachment A for aH the study reach observation sites. Results of all six runs for the whole study reach are shown in the summary output tables, Tables 4.16 and 4.17. Th~re are two complete tables, one for the low-flow case and one for the high-flow case, with three discharges in each case. Each column is explained on the last page of each table. Plots of the 23 cross-sections are presented in Attachment B, with all six computed water levels sketched on them. Several items from the analysis are worthy of discussion: Critical flow was computed for several discharges at Cross-section 103. This appears reasonable from field observations and for reasons given above in the discussion of the study reach characteristics. Cross-section 106.3 is not truly a surveyed cross-section. The original survey of cross-section 106, slightly upstream from 106.3 1 had some suspect data. The bottom elevations seemed higher than they should reasonably have been. However, no specific errors in the survey could be identified, so the cross-section was merely omitted. Other obs.ervations were available (at 106.3) of the river channel, so these were used 1 and approximate bank profiles were assumed. Slight inaccuracy may be present at this cross-section as a consequence. Middle Susitna Study Reach The Middle Susitna model was calibrated with Gold Creek discharges of 9,700; 17,000; 34,500; and 52,000 cfs. The USGS gage at Gold Creek was used as the standard for describing flows, but adjustments were made upstream and downstream of the gage locale. As in the upper study reach, modifications were based essentially on drainage area. Excepting Portage Creek and Indian River, both above Gold Creek, there are no significant tributaries to the Susitna within the reach. Thus, adjustment below Gold 4 -14 _, - - - - - - -· -· -· .·.-~ - ,_ . I - - -~ s3/b Creek was made at Curry, which is about halfway down the sub-reach from Gold Creek to the Chulitna confluence. Flows used for the various sub-reaches are shown in Table 4.4. Verification of the model was accomplished with discharges of .13,400 and 23,400 cfs, one for the low flow regime and one for the high-flow regime. All six computed and observed water surface elevations at the observation sites are tabulated for comparison in Table 4.18. Stage- discharge rating curves for all the observation sites (based on observed water-surface · elevations) are shown in Attachment A. The summary output tables are presented in Tables 4.19 and 4.20 (column headings are explained at the end of each table), and Attachment C gives the cross- section plots with computed water surface elevations for all 66 cross-sections. Points of interest in the analysis: Cross-section LRX-28 did not yield good comparisons between computed and observed water levels all the time, particularly at the lower flows. This is probably due to the multi-channel situation at the cross-section. With the crest gage being located on a side channel on the left bank, it may not be hydraulically connected with the main channel and thus have a water surface above or below the main channel 1 s. Cross-section LRX-4 had a location similar to that at· LRX-28, with several islands in the main channel and the crest gage adjacent to a side channel on the left bank. Its reliability is also somewhat suspect. However, all the other crest gages, the streamgage, and the staff gages are at single-channel cross- sections. The model initially computed critical flow at two cross-sections at certain flow levels. While these two cross-sections (LRX-25 and LRX-44) had steep or swiftly-flowing reaches near by, the determination of critical flow did not appear justified. It was felt that the problem showed up due to the long inter-reach distances. Thus, an 11 interpolated 11 cross-section was added downstream of each of the areas. The two interpolated sections, LRX-24.5 and LRX-43.5, were determined from elevation information upstream and downstream and integration of features from the aerial photographs. These cross-sections show up in the summary Tables 4.19 and 4.20, but they are not plotted in Attachment C since they are not 11 true 11 cross-sections. 4 -15 TABLE 4.1 ~.

The upper segment above the Oshetna confluence, the middle segment reaching to just below Devil Canyon, and the lower segment from near Indian River to Talkeetna. The upper segment flows southward from its various glacial origins near latitude 63°30 1 N for some 90 miles to latitude 62°40 1 N. The elevation in this segment decreases from about 2,600 feet aot the toes of the glaciers (which rise to above 10,000 feet) to 2,150 feet. This is a fall of sime 450 feet at an average slope of about 5 ft/mile. No notable concentration of fall occurs in this segment. The middle segment flows westward with a slight northward trend for about 90 miles from the Oshetna River confluence near longitude 147°251W to the downstream end of Devil Canyon (Indian River confluence) at 140°251W and 62°50 1 N. The fall in this segment is about 1 ,350 feet to elevation 800 feet, providing an average slope of 15 ft/mile. Concentrations of the fall in the middle segment occur in four reaches: at the Oshetna River, at Vee Canyon, just below Devil Creek, and in particular, at Devil Canyon. The lower segment flows in a south-southwesterly direction for ' about 40 miles from Indian River to near the town of Talkeetna at 150°051W and 62°201 N. The fall in this segment is about 450 feet to elevation 350 feet at an average slope of about 11 ft/mile. No notable concentration of fall occurs in this segment. Downstream to Talkeetna where the Susitna flow conJOinS with those of the Chulitna and Talkeetna Rivers, the Susitna's course is southward for 75 miles to sea level at Cook inlet at 61°20 1 N with an average slope of 5 ft/mile. No concentration of fall occurs in this southern segment of the river. 5.1 -Field Observations The geographic orientation of the river on the south slope of the Alaska Range results In air temperatures increasing along its course from the headwaters to the lower reaches. Whereas this temperature gradient may be due in part to the 2-degree latitudinal span of the river, it is probably due primarily to the 3,300-foot altitudinal difference from the lower to the upper reaches, as well as to the proximity of climate-moderating ocean waters to the lower reaches. In any case, the gradient gives rise to a period of time in the early stages of freezeup (late October- early November) in which the lower basin temperatures are s14/L 5 - 1 above the freezing point while the upper basin is at subfreezing temperatures. This was the situation observed on October 17, 1980, with late afternoon temperatures (4:30 p.m. ADT) above Watana being 30°F or lower while the temperature at Talkeetna was at about 39°F. Presumably, a similar springtime period occurs with temperatures straddling the freezing point at some inter- mediate point in the basin. This point would move in an upstream direction with upward trending temperatures (i.e. springtime) and downstram with downward trending temperatures (i.e. autumn). In both cases, this pattern of temperature affects the sequence and timing of ice cover events. As noted, on October 16 and 17, 1980, the foregoing autumn temperature situation was seen to prevail. Glacial melt from the headwaters cooled enough in its course through the relatively mild slope of the upper segment of the river to produce notable quantities of frazil flock and slush pans (15-25 percent surface coverage) under post-dawn air temperatures of 18°F to 14°F. In the fast-flowing rapids of the middle segment, relatively large quantities of frazil were being produced, which augmented the inflow of ice from upstream loading, to surface coverage of the river as high as 75-85 percent. As inflows from major tributaries along the source of the upper and middle segments had little, if any, ice content, the near-freezing temperature of the glacial melt is judged to be a significant determinant of the origin of ice from which a cover will develop and, therefore, of the timing of that development. Thus, the summer collection and storage of heat in the proposed reservoirs in the upper reaches of the river will produce significant changes in the autumn temperature regime in the downstream reaches and, therefore, in the timing and rate of cover development. Details of the observations made during the river freeze-up (1980) and breakup (1981) may be found in the Ice Observations report (R&M, 1981b). 5.2-Modeling of Ice Processes (a) Description of the Computer Models Acres' in-house computer models HEATSIM and ICESIM were used to simulate the ice processes in the river reach above Talkeetna. HEATSIM simulates a daily heat balance in the river reach to determine water temperature progressively downstream. Details of the model and its calibration to simulate Susitna river reaches are presented in Appendix A4 to the main Feasibility Report. The model is used to predict water temperature in the river and to determine the approximate location and time when water temperature reaches 32°F. This location is used as input to the ICESIM model s14/L 5 - 2 I Li r· I , r· ~=l c J . \ \j [ r [ !(' L G t u t b c which simulates the formation and progression of an ice cover and the water levels associated with the processes. The following paragraphs describe the ICESIM model in some detail. s14/L ICESIM Model Input Input data to the ICESIM model include streamflow, river cross-sectional details, and an estimate of ice flow into the study reach. Physical coefficients such as ice density, cohesion, and ice cover friction (Manning's n) are also input to the program. Standard values available in the literature are used in the model. Aspects of flow characteristics such as ice erosion velocity and critical Froude number for ice cover progression should also be defined. Based on the literature and field observations made in 1980-81, values were estimated for these parameters and are listed in Table 5.1. Model Backwater Calculations The I CESIM model includes a subroutine which calculates backwater profiles in the river reach to assess water levels at different cross-sections. The routine is similar to the H EC-2 model described in Section 4 but is less sophisticated with respect to hydraulic computations in order to accommodate the complexities of the ice process simulation. Effectively, this simplicity translates to less precise water level calculations (±1 to 2 feet), as compared to HEC-2 modeling accuracy which is to better than ±1', but it is considered adequate to provide representative results. This model was calibrated against the H EC-2 model results for a single river discharge as discussed below. Historically, freezeup has started at a river discharge of around 4,000 cfs at Gold Creek in the end of October and progressed above Talkeetna until late November/ early December when the discharge dropped below 3,000 cfs. Calibrating the backwater routine with observed water levels for a river discharge of around 3,000 cfs at Gold Creek proved exceedingly difficult due to critical or near-critical flow conditions encountered in the river reach analyzed. Post-project winter discharges will be considerably higher (around 10,000 cfs) as discussed in Appendix A 1 to the main Feasibility Report. It was therefore decided that the backwater routine should be calibrated against the H EC-2 model results for a discharge close to the 10,000 cfs. Field measurements 5 - 3 s14/L of water levels in the river reach had been made for a natural streamflow of 9, 700 cfs (at Gold Creek) and have been used in the calibration of the H EC -2 model (Section 4). It was considered appropriate to use this discharge to calibrate the backwater routine of the ICESIM model as well. A comparison of the HEC-2 and I CESIM routine calculations is presented in Table 5. 2 which indicates a reasonable agreement between the two model results. Modeling of Ice Cover Formation and Progression The model simulates the formation and progression upstream of the ice cover given the location of the leading edge of ice cover and the time of its occurrence. The model checks the stability of ice cover and adjusts its thickness consistent with ice supply, river goemetry, and hydraulics of the flow. The ice thickness is adjusted either by telescoping of the cover or by thickening, and the model proceeds to the next section upstream. Except for occasional minor bridging, the steep river slope in the reach does not permit ice progression by bridging. This is also generally confirmed by the river observations in 1980-81. Model Calibration An attempt was made to calibrate the ice process simulation model with the field data collected during the 1980 river freezeup period. It became apparent that the model could not simulate numerous critical or near- critical flows that occur in the river, due to the relatively large lengths of sub reaches modeled. Several intermediate river cross-sections were synthesized between surveyed sections to reduce these subreach lengths. Nevertheless, the model has been used to simulate ice formation and progression at average post-project winter flows. Several qualitative checks have been made to assess the accuracy of this simulation. These include general heat balance of the river waters, river hydraulic characteristics as observed in the field, and comparisons with similar studies elsewhere in the northern climate. It must be emphasized that precision of predicted water levels in the river under post-project ice conditions is rather limited (±1 to 2 feet). However, the width of the uncertainty band in the modeling does not have a 5 - 4 [ [ R lJ c [ [ r L l c significant impact on the simulation of the ice regime of the river above the Talkeetna confluence, due to limited progression (see Section 5.3). 5.3 -Results of Simulation Studies Studies were conducted for the following stages of project developments; 0 0 0 During construction of the Watana dam. Only Watana development operational. Both Watana and Devil Canyon developments operational. (a) Watana Construction Stage During this stage, no significant change in the river regime is expected since natural flows in the river below the damsite will be maintained with the proposed diversion facilities. No simulation of this condition was carried out. (b) Operation with Watana Development Only Heat balance analyses were made using the HEATSIM model in the 35-mile river stretch between Watana and Devil Canyon damsites. The analyses indicated that the temperature of the power flow from Watana would reach close to 32°F below Devil Canyon by about the third week of November under average climatic conditions. This is about a month later than under natural conditions and would delay the ice progression above Talkeetna by a similar interval. It was determined that an ice cover will be formed above the Chulitna confluence around the end of November with ice generated from the reach below Watana damsite. Ice simulation studies indicated that the ice front progressed upstream at roughly 0. 3 miles/day, a rate less than one-eighth of that observed in 1980 (Table 5. 3). The front reached some 15 miles upstream by the end of January 1 after which a thermal decay of the ice cover is expected due to increased air temperature and reduced cooling of the power flow from Watana. The ice cover formed in the reach above Talkeetna is expected to melt in place by the end of March 1 and the decay will proceed further down- stream thereafter. It is unlikely that any ice jam of significance will occur above the Chulitna confluence. Below the confluence, it is speculated that ice cover formation will be delayed by one to three weeks due to lower and delayed supply of ice from the Susitna, but progression of the ice front would not significantly differ from that under s14/L 5 - 5 natural conditions. However, the decay of the ice cover is expected to start earlier, by the end of March, due to warmer waters from the power development. Significant increase in water temperature from that under natural conditions is not expected near the river mouth. (c) Operation with Watana and Devil Canyon When both developments are operational, the temperature of power outflows from Devil Canyon is expected to be close to 39°F during the winter months (see Appendix A4 to the main Feasibility Report). As it progresses downstream, water becomes cooler from heat exchange with the atmosphere. By early January, it is expected that this water will cool to about 32°F near Tal keenta (see Figure 5.1). It is expected that very little ice cover will be formed in the river reach above Talkeetna under average weather conditions. Due to the warmer water temperatures above the confluence, ice cover formation and progress in the lower river will also be delayed. It is expected that ice contribution from the Chulitna, Talkeetna, and Yentna Rivers will cause an ice cover to be formed in the lower river, but this cannot be quantified at this time without field data on such ice contributions and further observations of river freezeup phenomena. (d) River Water Levels Under Ice Cover Conditions Under natural conditions, significant staging occurs at several points in the river during ice cover formation. Table 5.4 presents staging observations made during the 1980 freezeup period for selected locations in the river. With increased flows in the winter under post-project conditions, a significant rise in water level during ice cover formation can be expected near Talkeetna. Table 5.5 presents estimated water levels under pre-and post-project conditions. Below the confluence, the rise in water levels during ice cover formation under post-project conditions will progressively decrease downstream. More detailed river cross-section surveys and river freezeup observations will be necessary to confirm these estimates and speculations. 5.4-Reservoir Ice Cover Ice cover formation and growth in the Watana and Devil Canyon reservoirs will be substantially different from that in the corresponding river reach under natural conditions. An s14/L 5 - 6 [ r\ (': ' -u 0 f.'. l [ [ u [ [ r [ c ~ Q' assessment of the formation, growth, bank-ice deposition, and eventual decay of the reservoir ice is presented below. The initial ice cover on the reservoirs is expected to be formed with some 100 freezing degree-days (°F) after the surface water reaches 32°F. Based on available climatic data and the reservoir thermal modeling (see Appendix A4 to the main Feasibility Report), the initial ice· cover will be formed toward the end of October under average weather conditions. Once a stable cover is formed, its growth is accomplished chiefly by conductive heat loss to the atmosphere. Figure 5.2 presents estimated ice cover growth in the Watana reservoir over an average winter season. Devil Canyon reservoir ice cover would progress similarly. The only difference would be that several miles of this reservoir immediately below Watana dam may have open water year-round due to outflow temperatures from Watana of 39°F or higher. Near the power intakes at each development, open water stretches will be present because of larger velocities, as well as significant mixing with warmer (39°F) waters in the lower layers. Under normal operation, the Watana and Devil Canyon reservoirs will be drawn· down by about 90 and 50 feet, respectively, toward the end of winter. Thus, the ice cover formed on the surface would be deposited on the banks as blocks, with sizes varying from a few inches to about three feet. The deposits will be generally irregular and cracked due to irregular bank slopes and drawdown rates. Most of this bank ice is unlikely to melt until about the end of June, or earlier if the reset1 voir level is raised with spring floods. The ice cover in the reservoir itself will essentially melt in place. By late February or early March, the ice cover will slowly start to disintegrate with higher air temperatures and increased solar radiation on the surface. Operation of the power intakes may slightly alter the disintegration of ice cover close to the intake with convection mixing underneath the cover. It is expected that the ice cover in the reservoirs will completely dissipate by the end of May or early June, with warmer inflow waters and the onset of spring. During the period between March and May, the ice cover may become structurally weak due to the disintegration process, though its thickness may still be two to three feet. s14/L 5 - 7 TABLE 5.1 CALIBRATION COEFFICIENTS USED IN ICESIM Manning's •n• of Ice Critical Froude No. at Ice Front Erosion Velocity Density of Ice Cohesion of Ice s14/L 5 -8 0.050 0.120 6.5 ft/sec 47.0 lb/ft3 0.145 psi c E n [ c c TABLE 5.2 COMPARISON OF HEC-2 AND ICESIM BACKWATER ROUTINE RESULTS Computed Water Surface Elevation (ft, msl )* Cross-Section No. HEC-2 JCESIM LRX - 3 344.0 LRX - 9 378.1 379.0 LRX -15 452.5 453.5 LRX -21 510.0 511.7 LRX -27 542.9 544.4 LRX -34 616.0 615.8 LRX -41 659.9 659.8 LRX -47 690.6 690.3 LRX -54 733.2 733.8 LRX -61 832.9 834.2 LRX -68 850.6 * For Gold Creek discharge of 9700 cfs. s14/L 5 - 9 TABLE 5.3 ESTIMATED ICE COVER PROGRESSION ABOVE TALKEETNA Post-Project Conditions -Average Year Location of Leading Edge* Date Rivermiles Section December 1 No Ice Cover December 15 102 LRX-7 December 25 105 LRX-10 January 10 109 LRX-12 January 20 112 LRX-15 * With Watana only operational. s14/L 5 -10 [ u u L b •" E [ [ u r L TABLE 5.4 OBSERVED RIVER STAGING DURING ICE COVER FORMATION -1980 Location Talkeetna (LRX-3) Gold Creek Downstream end of Devil Canyon Devil Canyon Dam Site (Devil's Elbow) Immediately upstream of Devil's Elbow s14/L 5 -11 Approximate Maximum Observed Staging Above· 10/17/80 Open Water Level 3 - 4 ft. 5 - 6 ft. 12 -15 ft. 10 -12 ft. 3 -15 ft.

NOTES ON CROSS-SECTION PLOTS -UPPER SUSITNA 1 . 2. 3. 4. 5. . 6. Cross-sections are in sequence from the upstream to the downstream end of the reach. Number 101 is the most- upstream cross-section, and Number 121 is the most- downstream. Numbering is sequential except that Number 207 follows 107 and Number 208 follows 108. Plotting scales used vary somewhat from cross-section to cross-section. All are plotted with 10 feet to the inch vertically, but the horizontal scale used is either 100, 200, or 500 feet per inch. All cross-sections are plotted looking downstream. Water surface elevations plotted on each cross-section are those computed by the H EC-2 computer model. The streamflows used in this study reach and plotted on all the cross-sections (referenced to the Watana gage) were 8, 100; 17,200; 26,700; 30,700; 42,200; and 46,400 cfs. Flows on the plots specify the Watana flow, but at the cross-sections, they were actually adjusted for drainage area, as shown in Table 4.3 of the main report. At several cross-sections, water levels are not shown in low areas of side channels or sloughs. In some cases, this is because no river water is expected the·re at all. In other cases, there may be water, but no hydraulic connection is apparent; thus, no flow is there, and the actual water level there may be above or below that in the river. Where the cross-section is at a bend in the river or is split between more than one main channel, there are likely to be differences in water surface el~vation across the cross-section. The computer model, however, computes just one level, and this is understood to be the mean water surface elevation for the given discharge. susi13/h B - 1 tD I N 1 . . 1- . 0 . fJ~ ~ . . : '?I() ·f;, ~ : ,o ·fJ ·~ . .

Cross-sections are in sequence downstream end of the reach. upstream cross-section, and downstream. from the upstream to the Number 68 is the most- Number 3 is the most- 2. Plotting scales used vary somewhat from cross-section to cross-section. All are plotted with 10 feet to the inch vertically, but the horizontal scale used is either 100, 200, 250, 500 or 1000 feet per inch. 3. All cross-sections are plotted looking downstream. Water surface elevations plotted on each cross-section are those computed by the H EC-2 computer model. The streamflows used in this study reach and plotted on all the cross-sections (referenced to the Gold Creek gage) were 9,700; 13,400; 17,000; 23,400; 34,500; and 52,000 cfs. Flows on the plots specify the Gold Creek flow, but at the cross- sections they were actually adjusted for drainage area, as shown in Table 4. 4 of the main report. 5. At several cross-sections, water levels are not shown in low areas of side channels or sloughs. In some cases, this is because no river water is expected there at all. In other cases, there may be water, but no hydraulic connection is apparent; thus, no flow is there, and the actual water level there may be above or below that in the river. 6. Where the cross-section is at a bend in the river or is split between more than one main channel, there are likely to be differences in water surface elevation across the cross~ section. The computer model, however, computes just one level, and this is understood to be the mean water surface elevation for the given discharge. susi13/i c -1 n I ...-.:. 1 PREPARED BY • j ] 1 ' SUSITNA HYDROELECTRIC PROJECT CROSS-SECTION Number 6 8 ll .
