The data obtained from this program will be used for rapid determina- tion of subsurface conditions,correlation between borings,and to determine general stratigraphy at greater depths than those penetrated by borings in the river channel and in the relict channel area.Ground penetrating radar (GPR),seismic refraction,and borehole gamma logging methods were employed.The radar and seismic refraction surveys were run by a four-man field crew under the di rect ion of a Harza-Ebasco geophysicist.Two members of the team and the equipment and ins tru- - ments were provided by Harding Lawson &Associates. logging was done by a Harza-Ebasco geophysicist. The boreho Ie .- i .... The ground penetrating radar was used as a rapid reconnaissance tool to del ineate shallow overburden depths to bedrock ln the n ver channel, thereby allowing the selsmlC refract ion and dr i 11 ing programs to be used where they would be most effective.GPR was also used to deter- mlne lce thicknesses and rlver channel profiles to aid ln the safe movement of men and equipment over the frozen river surface . The purposes of the selsmlC refraction was to provide seismic sect ions delineating overall depth to bedrock in the river channel. A-I Borehole gamma logs were run in all open boreholes to assist in hole- to-hole correlations.The ultimate goal of the geophysical program was to provide a better understanding of subsurface conditions above bedrock. 1.GROUND PENETRATING RADAR (GPR)-RIVER CHANNEL 1.1 Data Acquisition The GPR survey was perfromed with a Geophysical Survey Systems,Incor- porated (GSSI),SIR-7 radar system.The system consists of a power supply,control unit,EPC graphic display recorder,and two trans- mitting/receiving antennas.All instrumentation was mounted in a Nodwell FN-20 flatbed snow vehicle and the antenna was towed behind. IJ!I!1 I i Two antennas were used for this survey: of 120 MHZ and the other of 300 MHZ. one with a central frequency The GSSI system uses radar technology to obtain a continuous high reso- lution electromagnetic profile of the subsurface.The depth of pene- tration is dependent upon the electrical properties of the subsurface materials and the frequency of the radar antenna employed,and may penetrate several tens of feet.The penetration depth was limited to approximately 15 feet for this survey. Figure A-I shows the locations of the fourteen radar profiles obtained between January 23,and January 26,1983.The profiles total 8486 lineal feet of coverage.The profiles that cross the river at the up- stream and downstream cofferdams and at the dam centerline were located by utilizing.on the ground,general topography.Profiles at other locations were positioned by taking bearings with a Brunton compass and making use of the survey reference marks available along with the A-2 - - general topography.Measurements along each line were made with either a tape measure or hip chain. For this survey,dielectric constants of 30 for saturated material and 81 for water were assumed in order to produce the profiles presented in Figure A-Z. 1.2 Cond us ions The primary objective of the radar survey was to locate local areas in the channel where overburden is very shallow (less than 15 feet below the surface). Since the bedrock surface was 1.n most instances greater than 15 feet the radar survey was primarily utilized to ascertain ice thickness and river bottom profile information.These data were used in constructing a topographic map of the surface of the river alluvium.The radar data was also used by the 1.ce building and survey crews to check 1.ce condi- tions in questionable areas of the river channel prior to moving equip- ment over the ice.The information was thus utilized in planning the l- I routes to be taken by the hammer drill rig during its river channel operation. 2.SEISMIC REFRACTION -RIVER CHANNEL 2.1 Data Acquisition The se1.sm1.C refraction surv~y was conducted with a Geometrics ES-12l0 l2-channel signal enhancement seismograph and 4 hertz Mark Products vertical geophones.The energy source was Kinestik explosives;Atlas - Staticmaster electric blasting caps were used to initiate the explo- s1.ons. A-3 Ten reversed refraction lines were run totalling 8785 lineal feet of geophone coverage as shown in Figure A-l.Each seismic line contained from one to three spreads of 12 geophones each with an interval of 50 feet between geophones.Shorter geophone spacings were used where necessary. Generally,two shots were detonated at e'ach end of each spread at dis- tances of 10 to 25 feet and 200 to -600 feet from the end geophones. All geophones were placed either on grounded ice or float ing river ice due to the seasonal conditions. 2.2 Data Reduction and Analysis During the seismiC surveYing the presence of a high speed ice surficial layer acted to mask seismiC arrivals from the slower velocity'of the underlying all uvial depos its.It was ant ic ipated that the bedrock velocity would be sufficiently faster than the ice so that it could be detected.This was the case with the first seismic arrival times from the ice preceding and obliterating the slower arrival times from the underlying river sand and gravel deposits,therefore,the seismiC velocity of the saturated alluvium was never actually measured.How- ever,the bedrock velocities were sufficiently faster than ice velocities so that with a long offset between the shot and geophone spread,seismic energy from the bedrock surface was detectable.Con- sequently,refraction profiles were run parallel or oblique to the river channel to take advantage of the long offset method. Compressional wave (p-wave)arrival times were determined by observing the first break on each of the 12 horizontal wave traces recorded by the seismograph.These arrival times were then plotted against the horizontal distance from the shotpoint to the receiving geophones and grouped by apparent refractors.Standard velocity/intercept time A-4 (Dobrin,1976),velocity/delay time (Cummings,1979;Hagedorn,1959; Scott et aI,1972),and ray tracing (Scott et aI,1972)techniques were applied to these data to provide P-wave velocities and thicknesses for refractors. 2.3 Interpretation- Due to the surface ~ce layer,veloc ity data were not obt ained for the saturated alluvium beneath the river bot tom.In order to make depth calculations,it was assumed that the velocities for this material range between 6000 and 7000 fps velocit ies for the alluvium prov ided the best fit.In those exceptions,6000 to 6250 fps velocities were used,which were still within the expected range. Seismic velocities of 14,750 to 18,000 fps.were interpreted as indica- tive of bedrock. 2.4 Conclusions Seismic profiles for S83-l and S83-3 through 10 are presented ln Figures A-3 through A-12,and show the interpreted bedrock elevat ions and assumed velocities in feet per second for the alluvium and bedrock. Also shown are the shotpoint positions,time-distance data,and depths to bedrock measured by hammer drilling,and seismic line intersections. Time-distance data for each se~sm~c line are shown ~n Tables A-I through A-IO.A summary of the velocities ~n the alluvium (Vl)and bedrock (V2),and the depth to bedrock are presented ~n Table A-ll. These velocities do not include those of lce or ice-bonded soils. There ~s generally good seismic profi Ie sect ions "... - ,,---------_._---_._---------_._------- correlation between borehole data and where geophone spreads actually cross A-5 the the locat ions of the borings.Typically the variat ion ~n the depth to bedrock between these sets of data ranges from 2 to 15 feet. The upstream end of 883-10 does not agree with data from DH-3,wh ich was drilled during previous exploration.This hole shows bedrock at 78 feet below ice surface while the seismic data indicates depths 20 to 30 feet deeper in this vicinity.It is'quite possible that extremely irregular bedrock topography in this location has distorted the seismic data. In general,the depth to bedrock was shallow (less than 25 feet)along the north shore at the downs tream cofferdam,moderately deep (60-80 feet)~n the center of the channel at the upstream and downstream cofferdams and at the ma~n dam,and very deep (greater than 150 feet) in localized areas between the main dam centerline and upstream coffer- dam.A discussion of each major seismic line follows. 2.4.1 Downstream Cofferdam Foundation ., I ProE les 883-1 and 883-3 are al igned along the north shore.Profiles S83-4 and 883-10 are oriented parallel to the course of the r~ver channel and are near the center portion of the channel. Profile 883-1 shows relatively shallow bedrock (2 to 27 feet)with a se~sm~c velocity of 15,300 fps.The apparent dip of the bedrock sur- face is to the east.An attempt to gather seismic informat ion across the r~ver channel along refraction Line 883-2 was made,but because of the short shore to shore distance,only direct arrivals through the river ice were recorded. Line 883-3 indicated a single velocity layer with an average seismiC velocity of 14,500 fps.This could be interpreted as bedrock at the A-6 - ,... - ,I""'" ".,., surface.Borehole data,however,indicates that rock 1S over 20 feet deep near this line.5ince the velocity 1S between that of 1ce and those noted as bedrock on other lines,it was concluded that the alluvium under this line 1S frozen or partly frozen. Profiles 583-4 and 583-10 provide subsurface information below the cen- ter of the river channel.The depth of'bedrock averages 75 feet and the se1sm1C velocity ranges from 15,000 to 17,000 fps.Both profiles indicate that the apparent dip of the bedrock surface is to the south. 2.4.2 Centerline and Upstream Dam Foundation Area Profile 583-5 intersects the centerline of the proposed Watana Dam, Profiles 583-6 and 583-9 are centered 900 and 1600 feet upstream (east) of the centerline,respectively.All three profiles are oriented. parallel to the course of the river and within the river channel. Profile 583-5 shows an undulating bedrock surface with an average depth of 70 feet.Bedrock velocities (V2)range between 14,750 and 18,000 fps.Bedrock begins to dip moderately to the east 1n the eastern prot ion of the profile.The lateral change in bedrock velocities could be caused by fracturing or shearing of the bedrock. Profile 583-6 could not be handled by convent ional computer mode 1 i ng techniques:,probably because of severe distort ion of the field data by near-vert ieal disp lacements 1n the bedrock topography.A de lay-t ime method (Cummings,1979;Hagedorn,1959)was app 1 ied to the arrival times.The,model indicates a vertical displacement of 80 feet in the bedrock surface and bedrock may be as much as 170 feet deep at the base of the scarp. A-7 Profile 883-9 shows a deep bowl-shaped bedrock surface.The maX1mum depth to rock is 162 feet;the seismic velocity is 15,500 fps. 2.4.3 Upstream Cofferdam Foundation Profile 883-7 intersects the centerline of the upstream cofferdam. Profile 883-8 1S located 550 feet upst'ream of the centerline and crosses the northeast portion of Profile 883-7. Both profiles show a slightly undualtirtg to level bedrock surface with an average depth of 65 feet and a velocity of 16,500 fps. 3.BOREHOLE GAMHA LOGGING -RIVER CHANNEL AND RELICT CHANNEL 3.1 Data Acquisition Natural gamma logs were run 1n all open boreholes drilled during the winter program using a Mt.Sopris Model II borehole geophysical logging system.With the except ion of DH83-4,all boreholes were logged through 2 inch PVC;DH83-4 was steel cased to 60 feet and open below 60 feet.Eight of the boreholes logged were located in the relict channel and 23 were 1n or near the river channel.The locations of the river channel boreholes are shown in Figure A-I. shown on Figures A-13 through A-47. 3.2 Analysis and Interpretation Individual gamma logs are The natural-gamma logs were all run at a speed of 10 feet/min.and at a time constant of 5 cps (counts per second)for good definition of gamma anomalies.Chart deflection was set at 5 cps per division horizontally and 10 feet per inch vertically. A-8 - Gamma logs of adj acent ho les were analyzed by matching log int erval s having the same amplitude and similar anomaly signature.Those matches were then checked against the borehole sample logs for geologic their reasonableness according to standard geofluvial processes ..... identification.Individual gamma/litho units were then checked for - 3.3 Conclusions The gannna ray profile along se~sm~c line DNA indicates that the gamma ray log is quite useful for extrapolation of point lithologic samples both vertically and horizontally.Unit E/F is recognizable in this ....profile and ref inements in the boundaries are suggested from its ..... examination. The gamma-ray profiles for the r~ver channel demonstrate a similar practicality ~n the much more complex geologic situation of rapid vertical and horizontal facies changes.The gannna ray anomalies recorded agree reasonably well with the point samples taken from the boreholes.Each of the river gamma/lithologic profiles permit better - - resolution of the river sections than the samples alone.

A Becker AP-IOOO hammer rig drilled 5,239 feet of borehole,using a percussive hammer,occasionally switching to a rotary attachment when drilling conditions became difficult·lD deeper boreholes.A lightweight rotary coring drill rig was mobilized late in the program for the river areas where ~ce conditions prohibited the use of the heavier hammer drill rig.The long year 38 rotary drill rig accounted for 398 feet of the total 5,637 feet drilled during the winter program. 1 .HAMMER DRILL RIG 1.1 Percussive Hammer The hammer drill ng used a diesel pile hammer to drive a double-wall p~pe while a reverse air circulation system removed the cuttings as the pipe advanced.The inner pipe of the double-wall pipe directs the incoming air through the annulus between the inner and outer pipe to the bottom of the p~pe.The returning air with drill cuttings then passes up through the inner pipe into an energy dissipating cyclone that vents the air from the sample.Specially des igned tooth bits are B-1 used to penetrate the soil formations and to direct the soil into the inner pipe.The drive pipe is withdrawn by a puller system comprising two SO-ton hydraulic cylinders operat ing tapered slips that grip the pipe. The hammer drill rig used for the winter program was an AP 1000 (All Purpose)manufactured by Drill Systems,'Calgary,Alberta.The basic elements of this rig include a Link Belt 180 diesel pile drive hammer delivering 8,100 foot-pounds per blow operating at variable speeds to a maximum of 95 blows per minute;a SuI lair Rotary Screw Compressor rated at 750 cfm at 250 psi;am 18 gpm Beam mud pump;a hydraulic hoist,a hydraulic pipe puller;a mast;and a cyclone. The hammer energy 1S delivered to the drive pipe when the hammer strikes the drive spout which sits atop the drive pipe.The double- wall drive pipe 1S designed so that only the thicker outer pipe trans- mits the hammer energy to the bit.The two sizes of double-wall pipe used in this program were 5-1/2 inch O.D.X 3-l/4-inch I.D.,and 9-inch O.D.X 6-inch LD.The 9-inch pipe was used for approximately half of. the footage in the relict channel while the 5-l/2-inch was used for the remainder of the relict channel and most of the nver channel.A triple-wall drive pipe system using a 7-inch pipe over the 5-l/2-inch double-wall was unsuccessfully attempted at the beginning of the program. There were two basic bit designs used with the drive pipe,crowd-in or web tooth and crowd-out.The crowd-in bit has the cutting edge dia- meter slightly larger than the outer pipe diameter which forces all the material within the hole up the inner pipe.The crowd-out bit,with the cutting edge at the inner pipe,samples only the material directly below the 1nner pipe and pushes the remainder aside as the pipe advances.A 5-5/8-inch web-tooth crowd-in bit was used almost B-2 ~ I - - , - - .... .... ..... ,.,., exclusively for the project.Crowd-out bits were used occasionally when crowd-in bits were unavailable. 1.2 Rotary Drilling The AP 1000 had the capability of rotary drilling by replacing the drive spout with a rotary drive head.One drive head,the Center Stem Recovery (C.S.R.),using a high-torque,-slow-speed gearing,advanced the 5-l/2-inch double-wall drive pipe by rotation.The C.S.R.rotary normally used standard tricone or button tricone bits.The same reverse circulation system used in hammer drilling was used for the c.s .R.rotary. The rotation of the drill pipe helped to reduce wall skin friction. This allowed more drilling energy to be transferrred to the drill bit and helped to increase penetration.Also,the C.S .R.rotary with a tricone bit was used to penetrate boulders.Unfortunately,the recovered sample was usually comprised of rock fragments and did not give a representative grain size distribution.For this reason,the percent by weight of fractured material retained on the 3/4 inch sieve was always recorded during testing to serve as an indicator of the crushing effect.Also,every change between C.S.R.rotary and hammer drilling,or change of drill bits,required the removal of the entire drill string which contributed to borehole instability and redrilling of caved borehole sections. The 7-inch,triple-wall system using the C.S.R.rotary and an 8-inch tricone bit was attempted in the last hole l.n the relict channel. Excessive wall skin friction limited penetration and forced the aband- onment of the borehole. B-3 The other rotary drivehead,the Diamond Drill Rotary,had a high-speed, low-torque gearing for N-size conventional and wireline core drilling through the drive pipe after bedrock or refusal was encountered. 1.3 Additional Equipment IlI\ I - .... A down-hole hammer fitting through the'drive p~pe was also used to drill a pilot hole ahead of the drive p~pe when the drive pipe encount- ered refusal.The down-hole hannner easily penetrated boulders and bed-.... rock,but did not penetrate the softer unconsolidated materials because the resilience necessary to complete the hammer compression cycle was reduced. Occasionally,a 2-7/8 inch tricone bit was used with the diamond drill rotary to penetrate very dense refusal zones where the hammer drill or the down-hole hammer were ineffective. To drill angle holes,two 4S-degree angle blocks were placed beneath the mast.Four 4S-degrees angles holes were drilled by the hammer drill in the river channel. 2.ROTARY DRILL RIG A light-weight rotary core drill rig was mobilized later in the program for the river areas where ~ce conditions prohibited the use of the heavier hammer drill rig.A Longyear 38,sectionalized for helicopter transport,performed standard diamond drilling using NX-size wireline with NC-size casing. B-4 .... -, - - .... 3.SAMPLING The reverse circulation system used on the hammer drill rig provid.ed a composite sample of the materials penetrated.A geologist/soil engineer cont inuous ly monitored the drill cuttings dropped from the cyclone.A sample was usually collected every five feet by first clearing the inner pipe.Then the pipe was driven one to two feet before retrieving the sample.Somet imes,when sample recovery was reduced,the sample sect ion was extended beyond two feet.The sample was classified and placed in a canvas bag for transportation to the field laboratory.Samples for moisture determination were placed ~n plastic bags and sealed. Disturbed but intact samples were recovered us~ng a split-spoon drive sampler.A 2-l/2-inch diameter sampler was used with S-l/2-inch p~pe, while a 3-inch diameter sampler was used with 9-inch pipe.The first two S-5/S-inch bits used were reamed for the express purpose of passing the 3-inch sampler. Standard penetration resistance blow counts per six inches of penetration were recorded during the driving of the split-spoon sampler for estimating the relative densities of the materials sampled.The material directly beneath the drive pipe is considered highly disturbed due to the hammering action of the drive p~pe. Blow counts were also recorded during the drive of the double-wall pipe for estimating material relative densities.However,the energy 'delivered by the diesel hannner was not always constant because the driller adjusted the fuel injection control pipe penetration rate . Also,the resistance to penetration,due to wall skin friction, increases with depth thereby absorbing an increasing amount of hammer B-5 energy that could be delivered to the drive bit.Therefore,drive pipe blow counts will not be used to estimate finite density values. Grain s~ze distribut ions run on those samples recovered by the hammer drill rig are not fully representat ive of the ins itu material s.The hammering action of the drive pipe bit fractures the coarse gravel, cobbles,and boulders producing a gradation skewed toward the fine - -fraction.The hammer drill system also has a tendency to recover a larger portion of the fine particles,especially when a cobble or boulder ~s pushed ahead or aside and the finer material troves into the displaced volume.At the other extreme,a small portion of the fine fraction was lost in the air vented from the cyclone and ~n water ~ overflowing the sample collection bucket.The air used in the reverse circulation system has a tendency to dry the material as it was troving up the pipe to the surface.This action increases the chance of losing fines through the cyclone. 4.DRILLING PERFORMANCE - Early ~n the program the 5-l/2-inch drive faulty welds on the threaded pipe ends. pipe sheared because of Drilling of shallow boreholes m the reI ict channel cant inued with the 9-inch pipe while the substandard 5-l/Z-inch pipe was being rewelded. Excessive build-up of skin friction along the drive p~pe walls limited - real is tic penetrat Lon to approximately 300 feet.Deep holes required additional air capacity and special additives for the air to prevent the cuttings from freezing in the bottom of the drive pipe.Also,the deep hole required several changes between hammer and C.S.R.rotary which generally caused caving of the hole due to the removal of the - drill string during changeover.In the two deeper holes drilled,the B-6 - - ..... - ..... borehole wall deteriorated enough to allow the circulating air to pass along the outside of the drive pipe rather than up the inner pipe.The drilling equipment limitations prevented the scheduled drilling and 1n- sta11ation of test wells. Occasionally,when shallow cobble and boulder zones were encountered, the drive pipe was deflected sufficiently to require redrilling of the hole.Deeper cobbles and boulders wou1e!bend the pipe,but the soil along the pipe would provide enough support that the pipe sections at the surface would not deflect.As a consequence,in several boreholes, the coring of bedrock was precluded due to the difficulty in passing the core barrel through the bent drive pipe.Other cobble/boulders halted the penetration of the drive pipe which also required redril1- ing • The hammer drill rig penetrated very well while drilling shallow holes (less than 200 feet)and in water bearing sands and gravels.Having the drilling and casing combined in one operation provided a rapid, stable borehole.In the river channel,particularly,the hammer drill rig provided useful information in a limited amount of time while penetrating difficult subsurface conditions.

Coarse grianed soils (sand,gravel)are further classified both by the uniformity of the gradation of the soil (GW,GP,SW,Sp)as well as the amount and type of fines (silt,clay)fil-ling voids in the coarse soils (GM,GC,SM,SC).Fine grained soils are further classified according to plasticity (CL,ML,CR,MH)as determined by Atterberg Limit tests. Thus,grain size analyses and Atterberg Limit tests are used to class- ify all non-organic soils into a group symbol Which defines the texture and plasticity of the soil.Each group symbol indicates that a soil classified as such should exhibit a broad range of the engineering pro- perties of strength,compressibility and permeability.This range is further defined if a measure of the relative density of the soil and moisture content are provided in conjunction with the group symbol. Given the group symbol,.relat ive dens ity,moisture content,and obser- vations of particle shape,it is possible to predict engineering pro- perties and anticipated behavior within an accuracy suitable for many engineering purposes.

Routine index property and classification tests were performed on soil samples taken during the Drilling Exploration Program. Soil index tests were performed to classify soils and determine their grain size distributions,plasticity indices,in-s itu moisture contents,organic contents,specific gravity,and compaction character- istics.Also,visual descriptions of soils were made. The procedures employed in the laboratory testing program were gener- ally in accordance with those suggested by the American Society of Testing and Materials (ASTM).When deviations from ASTM recommended procedures were made,they were noted on the test forms.The specific test procedures and variations from ASTM methods are discussed in the following sections: 1.PROCEDURES 1.1 Sample and Control Processing Samples collected during each shift of drilling were inventoried and recorded on the sample test schedule and inventory forms.The selected soil samples were than prepared for testing.Preparation of samples required splitting with a mechanical splitter to obtain representative portions for testing.Visual classifications were performed and the D-l results were recorded on the appropriate sheets thus starting the docu- mentation cycle. The untested portions of those samples used»and the samples not test- ed,were transferred to the storage cage for future use»as necessary. An accurate record of the stored samples with precise locations was kept to facilitate relocating samples for either further testing or visual examinations.Upon completion of each test,the tested portion of samples were passed through a 3/4-inch sieve to separate selected materials finer than 3/4-inch sieve.This material was used for back- filling of drill holes. 1.2 Particle Size Analyses Gradation analysis (sieve and hydrometer tests)was performed on selected soil samples,based on ASTM 0422-63 test procedures.All bulk samples collected from the Hammer Drill Cyclone used for sieve analysis met the minimum ASTM weight requirements.However»the majority of soil samples obtained with split-spoon sampler were usually smaller than this minimum weight.Whenever a smaller than ASTM recommended weight sample was used for testing,it was noted on the test data sheet. Because the hammer drill uses a diesel pile-driver hammer to penetrate the soil,thus breaking boulders,cobbles and gravel into smaller pieces as the hole is advanced»the soil samples obtained have a high percentage of mechanically fractured materials.This percentage of fractured soils retained on the 3/411 sieve were recorded on the test data sheet so that the effect of this fractured material on the grain size distribution could be accounted for. D-2 - .... 1.3 Atterberg Limits (Liquid and Plastic Limits) The classification of samples containing fine grained soils was deter- mined by performing Atterberg Limit Tests.The liquid and plastic limits were determined in accordance with ASTM 0423-66 and D424-59 test procedures,respect [ve ly •. The soil samples tested for plasticity indices were prepared utilizing two different methods,dry or wet method ,ASTM recommends "dry pre- paration of soil samples for grain-size analysis and determinat ion of soil constants"(ASTM 0421-58).In this method of sample preparat ion, the soil sample was air-dried and then sieved through a No.40 screen to obtain the minus 1F40 sample fraction for Atterberg Limit Indices Testings. In the wet method of preparation,the soil sample was first soaked 1.n water for 12 hours and then washed through a No,40 sieve.Both methods of sample preparation have been used at the Watana Site.The wet method was normally used for soil samples with large clay and silt clumps Which could not be early processed using the dry method, 1.4 Moisture Content ..... Moisture D22l6-71 content tests test procedure were to performed in accordance evaluate the water content with of the the ASTM soils encountered. Moisture contents were determined for most soil samples obtained with split-spoon samplers,and on those bulk samples Which were secured in plastic bags.No moisture content tests were performed on bulk samples kept in c19t~bags. D-3 1.5 Organic Content The organic contents of selected samples were determined by the I1stand~ ard method of testing for organic content of soils"(State of Alaska, 1980),also known as the organic ignition test.The samples tested were oven-dried for 24·hours at a temperature of 10S"C and the dry weight recorded.The samples were then weighed to the nearest 0.01 gram and placed in a tared crucible.The crucible containing the sample was then placed in a muffle furnace at a temperature of 950"C +50"e until all organic matter was combusted,usually about two hours.The samples,were then cooled to room temperature,weighed,and the percent of weight loss calculated and presented as the amount of organic materials. 1.6 Specific Gravity Selected samples were tested to determine the specific gravity,Gs ' of their soil constituents.Specific gravity tests were periodically performed to establish a representative range.The ASTM D854-58 test method was used for conducting specific gravity determinations. 1.7 Compaction Tests A limited quantity of standard and modified proctor tests were perform- ed to establish typical compaction characteristics of selected samples from the relict channel/borrow area.ASTM D698 and D1557-78 test pro- cedures were used for the standard and modified proctor tests,respect- ively. D-4 - - -ii, ,..... ! ..... r I - 1.8 Visual Classification Visual procedures,based on ASTM D2488--69 test method,were performed on the majority of soil samples to assist with the soil classifica- tions.Visual descriptions of soils such as color,dry strength, "toughness,dilatancy and roundness were recorded on each test data sheet. A summary of the results of laboratory testing performed during the river channel and relict channel testing program are presented in the lab test summary sheets Which follow.Interpretation of the laboratory gradation data is presented in a set of curves at the back of this appendix • D-5 ,... 2.LAB TEST SUMMARIES -I ~r .
