The Sediment Problem in South Africa Reservoirs
The reservoir sedimentation problem has been studied in South Africa from 1903 onwards. A substantial capacity reduction in reservoirs located in high sediment production regions has been...
Reservoir Sedimentation Mathematical Modeling
The main objective for this paper is to show how one can predict the sediment movement, and estimate the volume of the deposited sediments, which is considered as one of the factor affecting...

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...
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 Estimation of Extreme Floods in Brazil
In Brazil, the design flood of a large dam is calculated using either the Probable Maximum Flood criteria or the 10,000-year Flood. Recently a Guidebook has been written to help Brazilian...
Geostatistics: From Mining to Hydrology
Geostatistics originated in the mining industry to help estimate the amount of metal contained in a block or ore, from a systematic sampling of the block. In this paper, the major geostatistical...
Special Hydraulic Problems Related to Coastal Louisiana Drainage Systems
The urbanized coastal areas of southeast Louisiana present unique problems for hydraulic engineers. These problems relate to the design of drainage systems serving leveed areas with flat...

Debris Torrents in Nepal and Use of Reliability Engineering Concepts During Redesign of River Works
Debris torrents, generated by cloudbursts and by glacier lake outbursts, occur frequently in the Nepal Himalaya. A simple fault tree analysis is applied to the destruction of a diversion...
Storage Reallocation in Hydropower Projects of North Georgia
Over the past 40 years, the Corps of Engineers has built nine multiple purpose storage projects in Georgia, with hydroelectric power production as a major purpose. Six of the projects...
Spillway Crest Development through Model Testing on Chenderoh Ambursen Dam
The Chenderoh Hydroelectric Project on the Perak River in Malaysia was placed in service in 1930. The hollow Ambursen dam was modified in 1944 by the additions of a concrete cap with flashboards....
Regional Rivers Resource Assessment as a Tool for Hydropower Planning and Policy: The Pacific Northwest Rivers Study
In August, 1984, the Bonneville Power Administration (BPA) and the Northwest Power Planning Council (Council) initiated a study to provide information about important river characteristics...
Yacyreta Hydroelectric Project Turbine Design
This paper provides general information about this major hydroelectric project on the Parana River on the border between Argentina and Paraguay in South America. In addition, some specific...
