Design and Performance of Diversion Gates at Peace Canyon Dam
During construction of Peace Canyon Dam, river diversion was accomplished using a combination of cofferdams and temporary diversion conduits through the partially completed dam. Inlet...
Risk Assessment of System of Dams
The application of risk assessment to a series of dams on a river is presented here. A general discussion of the basic principles of risk assessment approach to dam engineering is given...
The Lower Mississippi River and the Coriolis Force
Weather patterns and large bodies of water respond to the forces generated by the earth's rotation. A large north-south flowing river, such as the Lower Mississippi River,...
Physical Modeling of Major Cutoffs
In 1987, a model study of Lock and Dam No.4 on the Red River in Louisiana required two major cutoffs and a lock and dam to be modeled. Although the Waterways Experiment Station has modeled...
Deposition at a New Dam Near Mount St. Helens
A sediment retention structure (SRS) is being constructed on the North Fork Toutle River in the state of Washington to trap sediments eroding off the 1980 Mount St. Helens debris avalanche....
International Research on Mechanics of River Bank Erosion?A Summary Overview
A brief overview is presented of research regarding mechanisms of river bank erosion and treatments. In the research river planforms, water stages, currents, waves, ice sediments, bed...
IJC Challenges in an Era of Uncertainty
Since its creation pursuant to the 1909 Boundary Waters Treaty between the United States and Canada, the International Joint Commission (IJC) has evolved into an effective mechanism for...
Rule Curve Operation at Terzaghi Dam to Pass the Probable Maximum Flood
Terzaghi dam is located on the Bridge River, a tributary of the Fraser River. The spillway was originally designed for the 1000-year flood. Probable Maximum Flood (PMF) studies completed...
First 10 Years of Operation of
The first turbine of the La Grande hydroelectric Complex (Quebec, Canada) was commissioned in october 1979. Since then, five reservoirs, two rivers diversions, three power stations with...
Sediment Evacuation System for Impounded Rivers
Current solution techniques for the reservoir sedimentation problem are presented and their rationale questioned. The need for focusing on the overall river transport regime is emphasized....
How Many Years to Fill with Sediment, a Sediment Study of Lake Powell on the Colorado River
A study to determine the current capacity and to update information on the life expectancy of Lake Powell was conducted by the Bureau of Reclamation. The study documented the present storage-elevation...
Intake Towers and Outlet Tunnels Adapted for Hydro
An intensive design project was undertaken with the objective of retrofitting two U.S. Army Corps of Engineers (COE) dam sites for hydroelectric power generation. The challenge of designing...
Design and Construction of the Moose River Hydroelectric Project
The project's main features are: a 7 ft high, 240 ft long cast-in-place concrete overflow weir; bell mouth entrance concrete intake structure with trashrack and trashrake;...
Cofferdams: An Integral Part of Small Hydro Design
Cofferdam construction costs can be a major factor in the viability of a small hydro development. For this reason, cost-effective design and construction are critical. A cost-effective...
J. C. Boyle Hydroelectric Project Spillway Model Study
The J.C. Boyle Hydroelectric Project is an 80 MW facility near Klamath Falls, Oregon. The project consists of a concrete canal, tunnel, parallel penstocks and two Francis turbines. Upstream...
Flow Characteristics in an Irregular Spillway Model
A physical model of the spillway for a proposed water supply reservoir near Meridian, Texas, was constructed to determine the optimum spillway design which would maintain an acceptable...
Freeboard Allowances for Chute Spillways
Allowances must be made for the physical phenomena which cannot be modelled, such as wave action, air bulking, splash and spray; the simplifications of behaviour implicit in the calculations;...
Physical Model Study of New York State Dam
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 six channels as the water passes...
Ghost Dam Safety Evaluation
Ghost Development, owned and operated by TransAlta Utilities, is near the eastern margin of the Rocky Mountain Foothills, approximately 33 km northwest of Calgary, Alberta. The development...
Licensing the Moose River Hydroelectric Project
This paper describes environmental considerations in the licensing and permitting of the Moose River Hydroelectric Project, a 12.2 MW development in Central New York State. It illustrates...
