The Role of Model Studies in Add-On Hydro Projects
The reasons for modeling add-on projects are reviewed, and guidance given for the process of determining, first, the need for modeling, and second, if modeling is necessary, whether physical...
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...
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...
Pit Turbine Technology for Low Head Hydro Projects
Manufacturers of hydro generating equipment have developed designs that are adaptable to existing dams and suitable for upgrading and redevelopment of existing hydro plants. The pit turbine...
Rehabilitation of a High Specific Speed Francis Turbine
An upgrade of two (2) 4. 06 meter diameter high specific speed Francis turbines is now in progress. These machines were originally installed by Allis-Chalmers in the 1920's...

This paper is presented in two parts. The first, presented by B. H. Adams, gives a general overview of the Pontook Project including major physical features and the financed turnkey approach...
The Design of the Nanpil River Hydropower Project
In 1980, the State of Pohnpei (then spelled Ponape) asked the Pacific Ocean Division of the U. S. Army Corps of Engineers to investigate the feasibility of constructing a hydroelectric...
Racine?5 Years of Successful Operating Experience with the World's Largest Bulb Turbines
In September 1982 two bulb turbine generating sets with a runner diameter of 7700 mm and a generator rating of 25 MVA were put into commercial operation at the Racine dam on the Ohio river....
Fire Protection at the Grand Coulee Hydro Project
In the fall of 1980 a rupture of one of the Project's 525kV transmission cables occurred and created a fire. Power from three Third Powerplant 700MW units was interrupted,...
Competitive Model Testing for Replacement Runners at the Wells Hydroelectric Project
The Wells Hydroelectric Project, located on the Columbia River, contains ten Kaplan-type turbines, each rated at 123,000 HP (91,720 kW) at a net head of 64. 9 ft. (19. 8m). The plant has...
