An Overview of Cold Region Considerations for the Design of the Eklutna Water Project
The paper presents a brief overview of cold regions considerations that were considered during the design of the various elements of the Eklutna Water Project in Anchorage, Alaska. The...
Water Treatment Facility Design for a Glacial Lake
The Municipality of Anchorage, Alaska has undertaken a major water supply project, the Eklutna Water Project, to satisfy the growing water demands of Anchorage. The source of raw water,...
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....
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...
Developing a Community Water System for Shishmaref, Alaska
This paper discusses a unique water supply system for the City of Shishmaref, a moderately sized Alaska Native community on Sarichef Island in the Chukchi Sea. A three million gallon reservoir...

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...
Geotechnical investigation: Cominco's Red Dog Mine Facilities
The siting of major facilities associated with development of the Red Dog Mine Complex in Northwestern Alaska on relatively warm permafrost soil and rock presented geotechnical engineers...
Effluent Dispersion Measurements Under Sea Ice
Field measurements of the dispersion of effluent from the Seawater Treatment Plant (STP) at Prudhoe Bay, Alaska, were made during April 1985. The primary objective was to determine whether...
Insulation Performance Beneath Roads and Airfields in Alaska
Evaluations of the long-term thermal performance of installations in Alaska for frost heave control have included sampling and testing of the insulations to determine the retained thickness,...
Waterfront Stabilization Project, Kaktovik, Alaska
This paper discusses an innovative 384-foot treated-timber cribwall design utilized to control rapidly accelerating thermal erosion and establish a roadway along the bluff on the Beaufort...
Wave Forces on an Arctic Monotower Platform
At offshore lease sites located along the western coast of Alaska, longer periods of open water can be expected. As a result, wave induced hydrodynamic loading will become a more significant...
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...
Finite Element Analysis of Concrete Armor Units Subject to Wave Impact
Concrete armor units are commonly employed for the protection of shorelines and rubble structures. Their design is primarily based on hydrodynamic stability. However, their structural...
