TBM Tunnel Friction Values for the Kerckhoff 2 Project
In the mid-1970's Pacific Gas and Electric Company began design of the Kerckhoff 2 Hydroelectric Project, which supplements the Kerckhoff 1 project built in 1919. The Kerckhoff...

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...

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...

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...

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...

Design Data of Pump-Turbine and Francis Turbine Units
Some basic statistical data covering geometrical and energy parameters for Francis turbine and Pump-turbine units are presented. These data are further compared as specific ratios for...

Selection of Turbine Diameter and Speed for Francis, Kaplan, and Pelton Hydraulic Turbines
This paper is a continuation of work presented at WATERPOWER '83 and presents up-to-date information on the selection of diameter and speed for Francis, Kaplan, and Pelton...

Pit-Type Bulb Turbines?An Economic Solution for Low-Head Applications
For improving the profitability of extremely low head power plants the pit-type bulb turbine conception was developed, based on extensive model tests and on the operating experience with...

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...

Optimisation of Bulb and Kaplan Turbine Runners
The paper presents a brief survey of the theoretical method used so far at Turboinstitut Ljubljana for axial runner design and analysis. Theoretically optimised runner is later experimentally...

Calculation of Blade Trunnion Reactions in Kaplan Turbines
A computer program is presented to calculate the blade trunnion reactions in Kaplan turbines. The program calculates the trunnion reactions for operation of the turbine at steady state...

Hydro Research and Plant Renewal
Obtaining extra energy or output from existing plants is the current topic when the question of refurbishing older turbine installation arises or when plant operating conditions can be...

Bureau of Reclamation Uprating Program
The Bureau of Reclamation is an agency of the Department of the Interior and was established in 1902 to oversee the development and conservation of the Nation's water resources...

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...
