Digital Governor Application ? Bradley Lake Project
The Bradley Lake Project has two impulse turbines rated at 60 MW each to provide power to the Railbelt region of Alaska. Solid state digital governors are utilized to respond to system...

Deflector Synchronizing and Governing
This paper is a survey of deflector control speed govern impulse turbines for synchronization to a grid, and for isolated operation. There are several advantages to deflector control versus...

Design Considerations for Radial Key Retrofit
A practise that is becoming more and more common is to retrofit hydro-electric generators with Radial Key Systems. There are significant design considerations that must be made to ensure...

Potholes East Canal Headworks Project
The construction of 6.5 MW Potholes East Canal Headworks in Washington required near vertical excavation of about 100 ft (30 m) through the existing earthfill dam founded on columnar basalt....

An Alternative Approach to the Maximum Flood Concept
This paper outlines an alternative to the current approach for determining the maximum flood of river basins. The condition of the maximum flood is derived from the convolution integral...

Utilizing Wetlands for Stormwater Retention
The design steps an engineer uses to develop natural wetlands to provide flood control while continuing to retain their natural functions will be analyzed. This paper will include a discussion...

Bishop Intake #2 Spillway Modifications: A Case History
This paper covers the history of the events leading to the modification of Southern California Edison's (SCE) Bishop Intake 2 to pass a site specific design flood. From the...

The Replacement of Penstocks at TVA Ocoee II Power Plant
The Tennessee Valley Authority (TVA) replaced the steel penstocks at its Ocoee II power plant near Ocoee, Tennessee. A total replacement was necessary because of severe corrosion on the...

Rehabilitation of the Dams at the Crescent and Vischer Ferry Hydroelectric Projects
This paper reviews the dam rehabilitation design and construction techniques used at the New York Power Authority's Crescent and Vischer Ferry Dams. The following are the...

Outlet Works Modifications at Abiquiu Dam
For the installation of a hydroelectric project at the Corps of Engineer's Abiquiu Dam in New Mexico, outlet works modifications that would not affect the structural integrity,...

Civil Design of the Sidney A. Murray Jr. Hydroelectric Station
This paper addresses the general civil design of the Sidney A Murry Jr Hydroelectric Station with special emphasis on the design requirements of the project's unconventional...

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...

Double Radial Gates for the Brunau Ice-Retention Weir in Switzerland
During the springtime thaw, the River Sihl, which flows from the south into the city of Zurich, Switzerland, carries large quantities of ice flow. In 1968, to protect the footings of a...

Three Dimensional Modeling of Concrete Dams with Cracks Using Boundary Element Methods
Determining uplift pressure distributions in cracks in a concrete dam requires coupling between crack hydraulics and the stresses and displacements occurring in the rock and the concrete...

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....

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...
