Simplified Model for Micro-Hydro Feasibility
A computer model was developed for evaluating the preliminary hydraulic and economic feasibility of potential micro-hydro development sites. Among the main objectives of the model are...
Computer Modeling and Applications
A series of programs is available to evaluate the hydrology, compute the capacity to generate energy, establish unit costs, analyze penstock surge pressures, and simulate ramping rates....
Ester West Slide?A Case History
An 80 foot high embankment was benched into graphitic schist permafrost on a north facing slope approximately 25 miles west of Fairbanks, Alaska. Soon after construction approximately...
Characterization of the Dalton Highway Foundation Soils
A case study is presented of the landform-based probabilistic-statistical route geotechnical characterization of natural foundation soils along the Dalton Highway. Landforms were mapped...
An Economical Approach to Receiving Coal by Rail in the Sub-Arctic Environment
During the period 1983 to early 1985 a multimillion dollar coal transfer facility was designed and constructed in Seward, Alaska. The facility transfers coal from rail cars to temporary...
Cold Regions Features of the Whittier Access Tunnel
A feasibility study and cost estimate has been prepared for a vehicular tunnel which would form a portion of a highway between the town of Whittier, Alaska and the east side of the Kenai...
Alyeska Reroutes Trans-Alaska Pipeline at MP 200
This paper discusses the 1985 wintertime repair/reroute to the Trans Alaska Pipeline System (TAPS). The rerouted pipe was approximately 4000 feet long and cost approximately 27 million....
Massive Ice Detection by Earth Resistivity
This paper presents two case histories utilizing remote sensing earth resistivity equipment to target subsurface massive ice locations. In one case, a number of probe locations were made...
Performance Study of the Lagoon at Inuvik, N.W.T.
Since 1957, Inuvik's sewage has been discharged into a lagoon situated northwest of the townsite. In 1982 the lagoon was upgraded to a two-stage system. Two primary cells...

This paper describes a method available for evaluating sewage treatment requirements in cold regions. The City of Whitehorse wastewater management situation has been used as an example...
Wastewater Plant Cold Weather Operational Problems
A questionnaire survey was conducted at biological wastewater treatment facilities in northern New England. Problems associated with various unit processes, due to cold weather operations,...
Arctic Stream Scour: A Case History
A small arctic stream on the North Slope of Alaska was monitored through one hydrologic cycle. The flow rate of the stream and the progress of its erosion through a breach into an adjacent...
Coal Mining in Alaska's Interior: Problems and Solutions
The Usibelli Coal Mine located in Healy, Alaska is currently the largest operating coal mine in the state of Alaska. The mine has recently increased production to nearly 1. 7 million tons...
Upper Delaware River Ice Control?A Case Study
During February 1981 a castastrophic breakup ice jam occurred along a reach of the Delaware River near Port Jervis, NY, causing 14. 5 million in damages. In February 1982 another breakup...
