The Contribution of Local Area Management Teams Under Severe Environmental Conditions
This paper outlines a Westinghouse managed turnkey hydro electric project located in remote southwestern Wyoming near Kemmerer. The dam provides watershed control for the Hams Fork River,...
Checking Turbine Performance by Index Testing
This paper discusses an index testing procedure used by TVA for measuring performance levels of its hydroelectric units. It also describes a current program for retesting generating units...
Design Criteria for Generators in Low-Head Hydro-Power Plants
Principal characteristics and design features of such generators are discussed and options and preferences in their selection mentioned. Effects on inertia constant, efficiency, reactive...
Index Testing?Relative Turbine Performance
The Index method of testing hydraulic turbines consists of making a test in which the value of power output and head are measured and in which the quantities of water and velocity head...
Sherman Island Hydro Cofferdam
The design and construction of an eight hundred foot long by sixty-five foot high cofferdam is discussed. The cofferdam was located to permit major renovation of the existing downstream...
Nanpil River Hydropower Project Pohnpei, Federated States of Micronesia
The Nanpil River Hydropower Project is a 1600 KW run-of-the-river hydropower project located on the tropical island of Pohnpei, Federated States of Micronesia. The hydropower project will...
Changing Stability Criteria: Effect on Older Dams
Many of the dams on the Georgia Power Company system were designed and constructed in the early 1900's. Changes that have occurred in stability criteria since construction...
Rehabilitation of Victoria Dam
Rehabilitation of a 54-year old thin concrete arch-buttress dam was completed without interruption of power generation using pressure injection of an epoxy adhesive. This paper presents...
The Lowell Hydroelectric Project: A Case Study
The Lowell Hydroelectric Project, located on the Merrimack River in Lowell, Massachusetts, consists of an existing dam, canals, and turbine generating equipment presently operating at...
Adfreeze Strength of Ice to Steel Pipe Piles as a Function of Temperature
A study was initiated to determine the adfreeze bond strength between steel pipe piles and freshwater ice as a function of temperature. Tests were conducted at an average strain rate of...
Design of Tension Member Insulated Anchor for Arctic Pipelines
This paper explores the latest development in above-ground waterflood pipe anchors currently being used on the SOHIO operated portion of the Prudhoe Bay Oil Field. The objective of the...
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)...
Soil Strength Recovery Using a Clegg Impact Device
The research described in this paper uses the Clegg Impact Device to determine the relative strength of a soil, and describes how this information can be used to develop the strength recovery...
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...
Testing of Admixtures for Seabed Strengthening
Samples from several offshore soil borings in an area of the Beaufort Sea were subjected to laboratory testing to determine the applicability of this method. The soils were mixed with...
