Two New Machines for Ultra Low-Head Hydropower
This paper outlines the development of two new types of positive displacement ultra low-head hydropower machines, the AUR Water Engine (AURWE) and the Salford Transverse Oscillator (STO)....
The Institutional Lender's View of Project Insurance Issues
The purposes of this article are to describe the typical insurance requirements of project financing institutions (particularly for projects with an insurable value of less than 20 million)...
Prospects for Hydroelectric Power Development at Corps of Engineer Dams
There are two basic approaches to developing hydroelectric power facilities at Corps dams. The Corps can develop projects at the request of Congress through the authorization process....
Grand Coulee Pumping/Generating Plant
The paper discusses the Grand Coulee Project history, including a brief review of landmark dates and events. Major general features of the Project are covered, including civil works, mechanical...
Computerized Engineering for the Hydraulic Design of Hydro-Turbine Stay Vanes
To design a turbine stay vane as an integral part of the spiral case/stay vane/wicket gate waterpassage, both the vane geometry and the gate/vane position must be developed and analyzed....
Coordinating Engineering and Environmental Activities in Hydropower Development
This paper reviews the role of hydropower project personnel, particularly the interaction between project management, engineering, and environmental sciences staff in project planning...
Hydropower Contract Conditions for Civil Engineering Works
Norwegian types of contract documents for hydropower construction work - especially the underground parts - have long had the reputation of being flexible as opposed to the traditionally...
Efficient Small Hydroelectric Plant Operation
This paper presents a review of operating and maintenance alternatives for small scale hydroelectric plants. The cost of operating a hydro project is largely determined by decisions made...
A Laboratory Study of Factors Affecting Wetted Snow Roads
A brief review of the the literature concerning the application of water to the surface of snow roads is presented. It is demonstrated that there is no general agreement on the proper...
The CBR Test Applied to Processed and Compacted Snow
The processes used during the past two decades to improve the snow bear a modest resemblance to conventional flexible pavement construction, thus the field CBR (California Bearing Ratio)...
Design Evaluations in Support of Offshore Facilities and Gravel Islands in the Arctic
Development of oil resources in Northern Alaska has involved the design of nearshore and offshore facilities and structures in the Beaufort Sea and Prudhoe Bay in water depths ranging...
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....
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...
The Effect of Water Supply and Sanitation Systems on Disease Patterns on Manitoba Indian Reserves
This study examines the links between water supply and sanitation and health on Indian reserves in Manitoba. Health data on water related diseases were obtained from health care agencies....
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...
Legal Concerns in Cold Regions Engineering and Construction
For a variety of reasons the potential for the imposition of liability and the potential for comparatively large damage claims is greater in cold regions. It is the purpose of this paper...
Expert Systems and Engineering Design Knowledge
As in many current AI (Artificial Intelligence) systems, knowledge processing is the most important issue in expert systems. 'Knowledge' in engineering applications...
Applications of Artificial Intelligence in Preliminary Structural Design
The field of Artificial Intelligence (AI) deals with the problems of modeling human intelligence. The application of AI to structural engineering has been limited, but potential applications...
Solving Finite Element Structural Dynamic Problems on Small Computers Using Semi-Explicit Methods
Numerical techniques based on the partial decomposition of a coefficient matrix, are developed for structural dynamic problems. Improved iterative techniques are discussed which could...
Managing Software for More Efficient Design
