Relative Survival of Juvenile Chinook Salmon Through Bonneville Dam on the Columbia River
Preliminary results of a multiple year study indicate that juvenile chinook salmon passing through the juvenile bypass system at Bonneville Dam second powerhouse during the summer have...
Rocky Mountain Project?Probable Maximum Floods
Probable maximum floods (PMF's) were estimated for use in designing spillways for the lower reservoir main dam and two auxiliary pool dams at the Rocky Mountain pumped-storage...
Dam Safety Rehabilitation of the T.V.A. Nickajack Hydroelectric Project
Safety of its dams has always been of great concern to the Tennessee Valley Authority (TVA). The agency has throughout its history enforced conservative designs, good construction practices,...
Junction Falls Dam Rehabilitation?New Design Incorporates Vintage Concept
Junction Falls Dam was constructed in a gorge of the Kinnickinnic River in 1920 to produce hydroelectric power for the city of River Falls, Wisconsin. In 1988, the River Falls Municipal...
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...
Brule Hydroelectric Project Inflow Design Flood Study
In 1987, Wisconsin Electric Power Company (WE) was directed by FERC to provide additional spillway capacity at it's 63-foot (19 m) high Brule Dam. Original spillway capacity...
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...
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...
Through-Flow Analysis for Rockfill Dam Stability Evaluations
Existing rockfill dams may have spillways that are not adequate to pass the current probable maximum flood (PMF), having been designed prior to the publication of the latest Hydrometeorological...
Rehabilitation of Dams, Spillways, and Hydroplants
Many older dams are in need of rehabilitation as a result of aging, deterioration, and more stringent safety standards. Concerns include deterioration of original construction materials,...
Dewatering Using a Floating Bulkhead Proves Flexible, Reusable and Cost Effective
Going beyond a traditional bulkhead dropped in place with a barge crane or crane hoist, a steel floating bulkhead was conceived to dewater powerplant intakes, gated spillway bays or outlet...
Sediment Removal from Sand Hills Aqua Farms Using a Sediment Evacuation Pipeline System
Reservoir sedimentation continues to deplete the world's reservoirs of valuable storage capacity. Several reservoir sediment removal techniques have been successful in regaining...
Imperial Irrigation District Water Conservation
Imperial Irrigation District (IID) and Metropolitan Water District (MWD) have entered into a Water Conservation Agreement to conserve 106, 110 acre-feet (1.31 ? 108...
Monthly Conjunctive Allocation of Water Resources for Eastern Arkansas
The objective is development and use of a conjunctive water resource model as part of a hierarchical approach. In this case, this program is developed to determine the monthly allocation...
Stepped Spillway Design for Flow Over Embankments
Many embankment dams have been identified as unable to pass their design flows without failure due to overtopping. The U.S. Bureau of Reclamation (Reclamation) is currently at the forefront...
Overtopping Flow Spillway for Baldhill Dam, Sheyenne River, North Dakota
An existing gated spillway structure for Baldhill Dam and Reservoir (Lake Ashtabula, North Dakota) is not capable of passing floods up to the probable maximum flood (PMF) without overtopping...
Application of Appropriate Technology in Hydroelectric Project Rehabilitation
Many older dams are in need of rehabilitation as a result of aging, deterioration, and more stringent safety standards. A primary concern is spillway and stability inadequacies resulting...
One Dimensional Finite Element Model for Spillway Flow
This paper summarizes the development and preliminary testing of a one dimensional numerical model termed 'CURVE1D.' The model is nonhydrostatic, including bed...
Design of High Capacity Spillways for Ritschard Dam, Colorado
A hydraulic model investigation was conducted by the Bureau of Reclamation to assist in designing the hydraulic structures associated with Ritschard Dam. Ritschard Dam will have a labyrinth...
