2. EXECUTIVE SUMMARY
The Susitna Hydroelectric Project is being designed to provide a stable,
economic, .electrical energy source for the Alaska Railbelt well into the 21st
century. This enterprise has raised numerous concerns within pub 1 i c and
private sectors regarding potential impacts to the seasonal discharges of the
Susitna River system, its aquatic habitat, and fishery resources. The Alaska
Power Authority (APA) desires to minimize the differences between the poten-
tially conflicting demands of reservoir operations for power production versus
maintenance of instream flow requirements for the fishery resources. In fact,
APA is considering various project flow regimes and operational scenarios
intended to optimize power production,_ insure project safety, and minimize
deleterious fishery impacts. To meet these goals, it is necessary to evaluate
each operational scenario objectively via analytical modeling techniques.'
However, to achieve significant results, the modeling effort must be coupled
with a reliable, short-term and long-term streamflow forecasting methodology.
In addition, the methodology should provide the most cost effective balance
between data collection and operational expenses versus predictive accuracy
and reliability. The primary objective of this project is to provide APA with
detailed information and recommendations to aid their identification of
priorities and selection of the system to be implemented.
OTT proposes to fulfill these objectives based on·the seven task work plan
summarized below.
Task 1: Determine data and operational requirements and costs of exist-
ing methodologies.
Task 2: Evaluate the output capability of available models.
Task 3: Establish a selection criteria matrix to prioritize method-
ologies.
Task 4: Determine hardware and software requirements and cost.
- 2 -
Task 5: Evaluate data availability and data acquisition costs to meet
model requirements.
Task 6: Recommend those models and field programs that are able to
achieve project requirements.
Task 7: Report
Descriptions of each task are provided in the Scope of Work section within
this proposal. Basically, the evaluation of operational costs and output
reliability and suitability to APA will be addressed via an in-depth library
research effort. Existing techni ca 1 reports will be eva 1 uated to determine
the data network size, modeling cost, and output accuracy. To be significant
to this project, the cost of the monltoring network used in each report
evaluated will be determined based on the installation and operational expense
of a similar sized network within the Susitna River basin. Model output
accuracy will be addressed by comparing the future predictions within each
eva 1 uated report to actua 1 conditions that occurred after the report was
published. In this manner, we will be able to provide APA with comparisons
between differing methodologies based on actual operational histories.
Additionally, each individual methodology will be evaluated for its output
accuracy versus monitoring network density and duration so that an optimal
system may be selected.
OTT's modeling experience is evidenced by the fact that we have successfully
completed over 500 hydrologic and hydraulic precipitation-runoff projects
throughout the western United States and Alaska. Moreover, we have recently
completed two state of the art studies concerning glacial hydrology processes
in Alaska. We offer a complete range of hydrologic services including design,
installation, operation, and maintenance· of large hydrological monitoring
networks; and computerized data reduction and analysis. We maintain a large
repertoire of computer models on line.
Our experience indicates that the major limitation of the recently introduced,
sophisticated models is their data base requirements. In order to realize
increased output precision, these models require extensive data input in terms
- 3 -
of the number of required monitoring stations and length of record. Without
sufficient field stations with relatively long periods of record, the advanced
models must rely on default values when data requirements are not met; the use
of default values severely limits the predictive accuracy of these advanced
techniques,. The most severe limitation, however, is not the costs of
increased monitoring sites but the minimum monitoring time that is required.
Few projects can afford the delay created by collecting 5 to 10 years of data
before calibration and verification of model output can begin. It is likely
that project schedule delays for increased data collection will be unaccept-
able to APA. Therefore, it is apparent that field data collection expertise
is as important to this project as modeling proficiency.
OTT has extensive experience in the design, installation, operation and data
analysis of hydrological and meteorological networks throughout Alaska and the
western United States. In fact, we are acknowledged as being the most experi-
enced Alaskan firm with in-house expertise utilizing both mechanical and solid
state monitoring devices. We have monitored Alaskan stream systems ranging
from small basins to larger watersheds such as the Beluga, Tanana, Chulitna,
and Eklutna River basins. In all cases, our field instrumentation has
achieved nearly 100 percent data capture in spite of severe cold (-35°F),
difficult access, and weather related servicing delays. As a result of these
successes, we are currently upgrading our field instrumentation from standard
mechanical devices to solid state digital recorders. OTT maintains the
capability to electronically read, transmit, process, and analyze the
digitized data base via computer, attaining the result of in-depth, low cost,
high precision data analysis. Our field expertise coupled with our modeling
experience insures a complete, detailed system analysis from field to final
product.

HYDROLOGIC MODELING EXPERIENCE
HYDROLOGIC DESIGN MEMORANDUM
HUMBOLDT RIVER BASIN, NEVADA
For the U.S. Army Corps of Engineers (COE), OTT team members provided flood
forecasting and reservoir storage modeling of three proposed dam sites on the
Humboldt River. The drainage basin studied encompasses 16,000 square miles of
watershed with critical water supply conditions. The COE model HEC-1 was
modified to incorporate snowmelt and runoff relationships. Detailed analyses
of these dam sites included the preparation of peak volume and frequency
curves, flood hydrographs, standard project floods, and project maximum flood
magnitudes for the Humboldt River system and its tributaries. The model was
calibrated for the entire basin to simulate winter, spring snowmelt, and cloud
burst flooding conditions.
WISCONSIN RIVER MODEL
WISCONSIN RIVER, WISCONSIN
The Stanford Watershed Model (SWM) with snowmelt routines was used to model
the entire 2 ,000-square-mil e upper Wisconsin River basin. This model was
deve 1 oped for use by the Wi scans in Va 11 ey Improvement Company to schedule
storage and discharge operations of 15 dams. Twenty years of hydrological and
meteorological records were used for calibration of snowmelt and runoff
prediction.
WATER RESOURCES STUDY OF THE TRUCKEE RIVER BASIN
CALIFORNIA AND NEVADA
An extensive streamflow routing and reservoir operations·model was developed
to determine domestic, municipal, and· industrial water supply sources and
demands within the river basin. This model included snowmelt runoff fore-
casting and operational diversions from Lake Tahoe and 10 other alpine reser-
voirs. The model also effectively dealt with a complex series of municipal
water supply demands, power and agricultural diversions, and minimum
- 6 -
streamflow requirements for fisheries. Water supply conditions were predicted
for a 50-year period.
PUGET SOUND WATER RESOURCES STUDY
WASHINGTON
The snowmelt version of the Stanford Watershed r~odel was used to synthesize
runoff records for a 100-square-mile watershed. Forty years of regional daily
flow records were input to provide operational forecasting capability to the
City of Seattle Water Department. The model also used hourly time steps of
meteorological data to predict snowmelt and precipitation runoff.
GLACIER RUNOFF MODELING
ALASKA
Analyses of selected glacial basins were performed to supplement expert
testimony during litigation. Synthesis .cif flood events was done for the
Gulkana, Wolverine, Nuka, Mendenhall, Hubert, and Lemon Creek glacial basins
using the snowmelt version of the HEC-1 model. The model was capable of
simulating the attenuation and delay of runoff due to glacial influences.
HYDROLOGIC ANALYSES FOR HYDROPOWER
PACIFIC NORTHWEST
OTT applied various modeling techniques to simulate the period and duration of
streamflows for numerous hydroelectric projects throughout the Northwest.
Long-term daily flow records were compiled and correlated to simulate project
site conditions. Synthesized annua 1 hydrographs and exceedence curves were
produced ·to evaluate power potential and bypass flow releases. Modeling also
incorporated scenarios of intrabasin transfer, spring fed accretion flows, and
snow pack prediction.

ADDITIONAL WATER RESOURCES INVESTIGATIONS
208 WATER QUALITY MANAGEMENT STUDY
ANCHORAGE, ALASKA
For the ~1unicipality of Anchorage, OTT collected and analyzed all \'later data,
described areas that had water quality problems, modelled impacts on streams
and lakes from pollution sources, formulated alternatives to mitigate pol-
lution problems, made presentations at public involvement meetings, and
developed a 208 plan.
WATER RESOURCE MANAGEMENT STUDY
SEATTLE, WASHINGTON
For the City of Seattle and Metro, OTT performed studies on the Cedar and
Green River basins that involved collecting data on water quantity and quali-
ty, and fisheries. The data was summarized and analyzed to determine the
relationship between water quality and impacts on the fisheries in the Cedar
and Green Rivers. Computer models were built to extrapolate this data into
the future for changes in the land use and point sources of pollution. The
study developed comprehensive water resource management plans for the Cedar
and Green River systems.
STOCKTON SHIP CANAL STUDY
STOCKTON, CALIFORNIA
OTT performed a study for the City of Stockton that required gathering hydro-
dynamic water quality and meteorological data during two intensive sampling
periods. This data was used to calibra.te hydrodynamic and water quality
computer models. The models were then used to predict the effect on the ship
canal of the discharge of advanced waste treatment plant effluent.

208 WATER QUALITY MANAGEMENT STUDIES
DENVER, COLORADO
For the Denver Regional Council of Governments, OTT reviewed, analyzed, and
developed _an inventory of existing water quality and waste source data. A
computer model was applied to simulate complex water quality interactions in
the metropolitan portion of the five-county study area. Alternative struc-
tural and nonstructural control systems were developed and tested by computer
simulation for both point and nonpoint waste sources.
WATER QUALITY MANAGEMENT STUDY
ST. LOUIS, MISSOURI
For the East-West Gateway Coordinating Council, OTT performed water investiga-
tions to determine impacts of hundreds of muni ci pal and industrial waste
sources and urban and agricultural nonpoint sources of poll uti on. Water
quality models were applied to streams and rivers in the area. Management.'
plans were evaluated and presented in public workshops.
SHASTA DAM MODEL OPERATION AND FLOOD STUDY
TEHAMA COUNTY, CALIFORNIA
OTT built a mathematical model of Shasta Dam to investigate floods in Red
Bluff which could have been controlled by Shasta Dam before 1945. This study
included a detailed review of Shasta Dam's operational policy since its
construction. Local inflow between Shasta Dam and Red Bluff was quantified
for the last 76 years. The model was then operated to produce a 76-year flood
record for the Sacramento River at Red Bluff as if the dam had been in place
the full time. The results of this study identified the 100-year flood flow
at Red Bluff, which was used by the County.in their flood insurance study.
URBAN STORMWATER AND COMBINED SEWER OVERFLOW
MILWAUKEE, WISCONSIN
For the Milwaukee Pollution Abatement Office, OTT determined the storm of
record and the size of the collection and storage system that would contain
- 9 -
the combined sewer flows generated from this storm and the sanitary system
from the city. Mode 1 s were app 1 i ed to determine po 11 utant loads caused by
overflow into rivers. Expert witness services were provided for the city in a
court case on combined sewer overflows.
FLOOD STUDY
REDDING, CALIFORNIA
For the City of Redding, OTT determined the flood limits of Olney Creek for
present and future urbanization conditions. The ·Shasta County Hydrology
Manual was used to determine the 25-and 100-year flood hydrographs. The
HEC-2 computer program was used to determine channel capacities. Stormwater
management alternative combinations of channel improvements and upstream
storage were tested. An inventory of potential dam and reservoir sites was
conducted.

6. SCOPE OF WORK
Task 1: Evaluation of modeling requirements for streamflow forecasting in
the Susitna Hydroelectric Project area
Essentially, APA requires a predictive methodology that offers cost effective
analyses of various reservoir operational scenarios. Moreover, the model
effort must be coupled to a reliable, short-term and 1 ong-term streamflow
forecasting methodo 1 ogy to achieve significant cone 1 us ions. Mode 1 require-
ments include its applicability to a large, multiple tributary stream basin,
reservoir and river routing capability, long-term forecasting from snow pack
and seasonal or monthly climatological data, short-term forecasting from daily
or six-hourly time step weather forecasts, and the ability to incorporate
glacier mass changes. These requirements will be identified in greater detail
and form part of the initial selection criteria matrix. In fact this task can
be considered as a primary filter that will identify and reject those models
that cannot fulfill the project goals. In this manner, the criteria matrix
will be applied in detail to the remaining models that have a documented
history and demonstrated performance capability.
Task 2: Capabilities of existing streamflow forecasting models
Our modeling and field instrumentation experience will be combined with
comprehensive literature. research to define the application, capability, and
costs of the complete field instrumentation and modeling system. Existing
technical reports from private consultants, the National Weather Service
Forecasting Center, Alaska state agencies, U.S. Geological Survey, U.S. Army
Corps of Engineers, and other municipal agencies and organizations throughout
the western United States and Alaska will be evaluated to determine data
acquisition costs, modeling costs, and output accuracy. To be significant to
this project, the cost of the monitoring network used in each report evaluated
will be determined based on the installation and operational expense of a
similar sized network within the Susitna River basin. Model output accuracy
will be addressed by comparing the future predictions within each evaluated
-17 -
report to actual conditions that occurred after the report was published. In
this manner, we will be able to provide APA with comparisons between differing
methodologies based on actual operational histories. Additionally, each
individual methodology will be evaluated for its output accuracy versus
monitoring network density and duration so that an optimal system may be
selected.
Our experience has shown that the most cost effective and useful model infor-
mation is available from the USCOE/NWS Columbia River forecasting center, the
California DWR/DNR Sacramento forecast center, and the upper Mississippi NWS
forecast center in Minneapolis. Existing models with the most potential to
meet this project•s requirements are the U.S. Army Corps of Engineers SSARR
model, the SAC-SMA model as modified by Burnash and Ferral, the NWS River
forecast system, and the Stanford watershed model (in various versions) with
routing and Eric Anderson•s snowmelt modifications.
Task 4: Selection criteria for modeling system
A selection criteria matrix will be established for detailed evaluation of the
models that were identified for further analysis in Task 1. In general,
criteria to be evaluated include software availability, memory and storage
requirements, ease of operation, documentation (complete and usable),
operation a 1 experience, set-up cost, calibration and forecasting cost, data
input cost, and output format options. These criteria should be met if there
is potential for use of this model as an operational model for reservoir
releases, etc. An operational model should be easy to operate (user
friendly), have a documented history of use, and be well known in case future
modifications or adjustments are required. More detailed evaluation would be
made of model routing procedures (availability of options such as kinematic
wave, muskingum, lag attenuation, glacier routing); time steps (hourly, daily,
monthly); length of simulation; snowmelt routines (availability of options
such as degree-day index, energy balance, snowpack accumulation, frozen
ground, distributed model for elevation zones); snowpack variables (depth,
water content, albedo, cover, etc.); meteorological data requirements
(temperature, dew point, wind· speed, precipitation rate, etc.); and
-18 -
r--------------~~~----~------------
infiltration routines (availability of options such as Hortons, constant rate,
SCS curve methods, etc.). Additionally, s imul ati on accuracy versus expense
(evaluated in Task 2) will be used to select the most optimal modeling system
to meet APA•s needs.
Task 5: Data requirements for the selected modeling system
Suitability, modification, and application of existing data to the modeling
system will be described. Data requirements for a range of forecasting
accuracy and cost for both short term and long term forecasts will be
described. For a range of these alternatives, requirements for stream gages,
meteorological stations, and telemetry will be determined.
Task 6. Recommended set-up of modeling system
Set-up and operation of the selected modeling system will be described for at
least five alternatives covering a range of accuracy and cost. Sensitivity
testing derived from previous use of the modeling system and examination of
its internal p,rogram will be provided in terms of data input requirements,
costs, and accuracy.
Task 7. Report
A comprehensive report will be provided describing the methodology and results
of the tasks in this work plan. An annotated bibliography will be provided of
all appropriate modeling techniques identified in thi_s study.

EXPERIENCE
Mr. Dorratcague is a principal of Ott Water Engineers. He has
been Horking in the field of hydrology and hydraulics since
1972. His main area of concentration has been computer
modeling of hydrodynamics and water quality. His experience
on projects includes the folloHing:
o Developed cost and hydrologic computer a1gorithm
models for the Northwest Power Planning Council's
Hydropower Data Base. This included calculation of
energy costs and development of a standard procedure
for hydrologic analysis for the NorthHest states.
o California coastal storm surge analysis. Used the
CAFEl storm surge model (developed by MIT) to model
storm surge at several sites along the California
coast for the Federal Emergency r:anagement Agency.
o Performed the two-dimensional hydrodynamic and water
quality modeling of Lake Wisconsin. Currents due to
reservoir operation and winds were modeled. Nine
water quality constituents were also simulated and
the resulting model was ·employed to evaluate waste
discharges from a proposed industrial planto
o Managed and performed the numerical modeling of
storm surges on the coast of the Arctic Ocean. One
model was a finite difference model covering a large
area. The other was a finite element model applied
in greater detail to simulate surges in Prudhoe
Bay.
o For Intersea Research Corp., used finite difference
computer simulation models to analyze coastal storm
surges at Hoonah, on the coast between Valdez and
Cordova, and four sites off Prudhoe Bay including
Dinkim Sands.
o For the City of Nome, Alaska, determined the wave
and storm surge levels and predicted impact upon a
proposed wastewater treatment plant upgradingo
DENNIS E. DORRATCAGUE
o Responsible for flood Insurance studies on the
viashington and. Oregon coasts. v,ork included
analysis of storm wave runup on beaches and storm
surges on the coast and in bays and estuaries with
river flow inter-relations. Mr. Dorratcague
developed two-dimensional coastal surge and wave
tiacking models which have been adopted by the Flood
Insurance Administration for use on the Pacific
Northv1est Coast.
o Performed a water quality modeling study on the
Humboldt River in Nevada. Loaded the QUAL3 water
quality model on the State of Nevada's IBM computer
system. This model was run to simulate 12 water

EXPERIENCE
Mr. Barrett joined Ott Water Engineers, Inc. (OTT) in 1979 after successfully
completing his graduate studies in Colorado. His studies emphasized the
study of hydrology in relation to mining and industrial development, geo-
thermal potential, and domestic utilization.
Over the past ten years, Mr. Barrett has participated in a variety of pro-
jects including the following:
o Currently performing hydrology and hydraulics investigations for
both the Hunicipality of Anchorage's Eklutna Hater Supply and West
Interceptor Projects. These studies include stream cross section
and thalweg profile surveys, statistical analyses of discharge
data, and stream scour depth calculations for pipeline crossing
designs at Ship Creek, Peters Creek, Fossil Creek, Campbell Creek,
Eagle River, and Eklutna River near Anchorage. The crossing design
hydrology/hydraulics inputs include 100-year flood flows, eleva-
tions, profiles, 100-year floodplain delineation, scour depth cal-
culations, channel stability, and lateral migration rates as well
as determination of flood risk and diversion requirements during
