Unique Design Used for Collapsible Gate
The collapsible gate on the Wausau Dam is unique; there is only one known that is similar in design. The collapsible gate, which looks like an inverted V, was designed by Mead and Hunt...
Superplasticized Concrete for a Prefabricated Powerplant Structure
This paper describes the use of superplasticized concrete in extremely difficult placements inside a restricted access preassembled powerplant structure (PPS) of a 192 MW Sidney A Murray...
Raising of King Talal Dam
The King Talal Project is located on the Zarqa River, a Jordan River tributary, in Jordan. An existing embankment dam, 100 m high, built in the mid-seventies by the Jordan Valley Authority...
Evaluating History?The Edison Sault Powerhouse
The hydroelectric facility owned by the Edison Sault Electric Company at Sault Ste Marie, Michigan was an engineering marvel when it was designed and constructed. This paper explores the...
Design of Penstocks in Severe Earth Slide Locations
This paper deals with the problems of locating a penstock for a small hydroelectric plant at a site in Northern California that experiences considerable land movement during the rainy...
Avoiding Vibration in Penstocks
One objective of this paper is to indicate the potential sources of pressure pulsations within a hydraulic conduit system and the range of forcing frequencies associated with these sources....
Penstock Rehabilitation
The deterioration of aging penstocks is a common problem at many existing hydroelectric plants. A comprehensive understanding of the physical condition and functional limitations of an...
Prefabricated Power Plants, Experience and Prospects
This paper presents the prefabrication concept applied to the Greenup (Greenup Locks and Dam, Ohio River, 72 MW, 1982) and the Sydney A. Murray, Jr. (Old River Control Structures, Vidalia,...
Rocky Mountain Project?Overview
The Rocky Mountain Project, in Northwest Georgia, will be a three unit hydroelectric pumped-storage project with 850,000 kW installed in an above ground powerhouse. The gross water volumes...
Hydraulic Model Studies?Pak Mun Hydroelectric Project (Thailand)
The paper presents briefly the hydraulic problems related to the project which were successfully solved by the 1 to 100 scale hydraulic model study carried out at the Asian Institute of...
Hydraulic Aspects of West Delaware Tunnel Hydroelectric Development
Construction of a 7,500 kilowatt hydroelectric plant at the end of a 70 kilometer long water supply tunnel posed unusual hydraulic conditions that needed special consideration. Cooperation...
A Rocky Mountain Project Intake/Discharge Channel Flow Simulation Study
A two-dimensional depth-integrated finite element flow model was applied to evaluate pumping and generating flow conditions at the Rocky Mountain Project powerhouse intake/discharge channel....
Physical Hydraulic Modeling for Construction of New York State Dam Hydroelectric Project
The New York State Dam is located on the Mohawk River near its confluence with the Hudson River. Downstream from the dam, the river flow is divided into four main channels as the water...
Field Tests of a Lewiston Pump-Generating Unit
An extensive field test program was undertaken on a Lewiston Pump-Generating Plant (LPGP) unit at the Niagara Power Project, owned and operated by the New York Power Authority. The objective...
Evaluation of Turbine Intake Velocity Criteria
The paper addresses the effect of intake flow distribution on turbine performance at low-head projects. Field and model test data are used to raise the question of whether typical turbine...
Hydraulic Transients in the Operation of Small Hydro Plants
Adequate governing stability is a primary consideration for most large hydroelectric generating units. However, almost all small units installed recently in the United States are intended...
