Osoyoos Lake Control Structure
The new Osoyoos Lake Control Structure has been built on the Okanogan River at Oroville, Wa. The site is about 2 miles downstream from the outlet of Osoyoos Lake, and about 9 miles south...
The Gem State Hydropower Project
The Gem State Hydroelectric Project is located on the Snake River about 5 miles southwest of the City of Idaho Falls, Idaho. The project consists of a 40-foot high, 900-foot-long earth...
Design and Operation of a Differential Surge Tank
The differential type of surge tank is more effective in operation than the simple type because it reacts more quickly to load changes of all sizes. The differential tank is also usually...
Long Lake Dam Model Studies
The Long Lake spillway was designed at the turn of the century as a standard ogee section with an upstream batter for a maximum head of 179 feet (55 m). It did not include any energy dissipator....
Headrace Design Studies for the Jim Falls Hydro-Redevelopment Project
The 48 MW Jim Falls Hydropower Redevelopment project on the Chippewa River, Wisconsin, required extensive model studies to facilitate debris sluicing and to prevent intermittent vortex...
Mountain Jungle Intakes?Design and Model Study
Nine intakes of various sizes and designs supply water to the two high head power plants in the Sungai Piah Hydroelectric Development in Malaysia. The intakes are located on steep mountain...
Hydraulic Design and Performance of Discharge Facilities at Revelstoke Project
Revelstoke Project is located in southeastern British Columbia on the Columbia River, 130 km downstream of the Mica Dam and approximately 5 km north of the City of Revelstoke. The project...
Hydropower at Navigation Projects
Hydropower at navigation projects has been found to be compatible with the intended use of the project; however, it is important for the hydropower developer and the project owner to be...
Layout of a Powerhouse Adjacent to Lock and Dam Structures
An approach flow to a powerhouse intake adjoining existing lock and dam structures may cause a significant reduction in the efficiency of the powerhouse and give rise to an economically...
Low Head Hydraulic Model Justifies Cost
In many cases, developers of low head hydroelectric plants fail to use physical hydraulic modelling as a tool in the design process. Economic constraints are often cited as the primary...
Model Studies for Potential Modification of Pardee Spillway
East Bay Municipal Utility District, a public water supply agency in the San Francisco Bay Area, is examining the spillway adequacy of its primary water supply reservoir. Flood routing...
Application of Split Roller Bearings in Small Vertical Hydro Turbines
The elimination of lower turbine bearing problems with regard to reliability and water flow contamination was the main concern of this project. A design was needed that would fit the existing...
Free-Rotor, River-Velocity Turbine
This paper discusses the development of a very simple and inexpensive underwater turbine which will extract power ranging from a fraction of a HP up to 20 HP from the velocity of the running...
Generators with Shaft Mounted Turbine Runners
Water turbine runners mounted on an extended generator shaft are often specified to eliminate turbine bearings and the flexible shaft coupling. Two bearing single shaft turbine generator...
Upstream Elbow Tubular Turbines for Low Head Applications
This paper presents standardized Neyrpic tubular turbines for Pontook and ByPass Hydroelectric Projects. Upstream elbow turbines have been selected for those sites. In this paper, the...
Turbine Casing and Distributor Hydraulic Design
Interactive casing and distributor hydraulic design and flow analysis software has been developed and tested. Until now, its application is limited to radial distributor turbo-machines....
The Value of Model Testing in Computer Aided Pump and Turbine Design
