Geotechnical Aspects of River Bank Erosion
The principal geotechnical mechanisms of river bank failure are identified on the basis of extensive field investigations on many different river systems. The role of each factor depends...
Groins and Vanes Developed Basing Upon a New Concept of Bank Protection
At curved bends, scour at the outer bank always accompanies deposition at the inner bank. A highly efficient river course for flood flow is considered to have a small lateral gradient...

State-of-the-Art Report: Mexico
Design recommendations for groins and spur dikes are presented. For groins the most important ones are: to build them with sloping crests, orientated downstream and maximum spacing of...
Control of Bank Erosion in The Netherlands. State-of-the-art
In the Netherlands the protection against flooding and the effects of inland navigation have always been extremely important. Many problems related to these items, among them erosion and...
Design, Construction and Testing of Repairs to the Low Level Outlets at Terzaghi Dam
Operation of the low level outlets (LLOs) at Terzaghi Dam in southwestern British Columbia resulted in severe cavitation at operating heads significantly lower than design. Modifications...
Handling of Intake Bulkhead at King Talal Dam
During raising of King Talal Dam in Jordan in 1986, the existing intake wheel gate provided at the inlet of the project Low Level Outlet Works (LLOW) tunnel was found inadequate to withstand...

The Computer Mapping Center of the Detroit District, U.S. Army Corps of Engineers (USACE) is developing a Geographic Information System (GIS) to contain physiographic, demographic, and...
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...
Elements of a Coastal Stormwater Drainage System
Several elements in the design of a stormwater drainage system that outfalls to the ocean are discussed. The paper discusses a study conducted of the Ocean Lakes Watershed near Myrtle...
Status of Hydropower Development at Corps of Engineers Dams
The Corps of Engineers is the largest single supplier of hydroelectric power in the United States with 74 projects and an installed capacity of 20,839 MW. In addition, 33 Corps projects...
The Development and Writing of the ASCE/EPRI Hydroelectric Guidelines
In the Spring of 1989, the American Society of Civil Engineers (ASCE) and the Electric Power Research Institute (EPRI) jointly published their Civil Engineering Guidelines for Planning...
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...
Computerized Measurement of Turbine Flow and Performance, Including Penstock Protection
The application of computer technology now makes it possible to measure turbine flows accurately, reliably and economically. The measurement is based on the differential pressure produced...
Electrical and Mechanical Design, Commissioning, and Performance of the Moose River Hydroelectric Project
The Moose River Hydroelectric Project is a single-unit run-of-river hydroelectric facility located near Lyonsdale, New York, and was developed by a private firm. The generating equipment...
