Some Pertinent Considerations in Dam and Reservoir Design
Two important considerations in designing and constructing a multipurpose earthdam and reservoir are to minimize losses in the event of dam failure because of overtopping, and to conserve...

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...

Hydrometric Networks Serving Hydropower Needs
The Water Resources Branch is the national agency that collects, interprets and disseminates standardized surface water quantity and sediment data and information in Canada. The Branch...

Hydraulic Model Studies - Sidney A. Murray Jr., Hydroelectric Plant
The power plant is located at the Old River Control of the Lower Mississippi River (Louisiana). It consists of an intake channel about 5000 ft long, a power plant with eight bulb units...

Modeling Sedimentation Problems at Hydro Developments
Sedimentation embodies the processes of erosion, transportation and deposition of sediments. At hydro developments, sedimentation can create problems. Computer sedimentation models (CSM's)...

Storing Sediment and Freeing Fish
When Mount St. Helens erupted in May 1980, it sent a river of pyroclastic ash and other debris into Washington's North Fork Toutle River Valley. The resulting debris pile...

Sediment Transport Modeling
This is the Proceedings of the International Symposium on Sediment Transport Modeling, held in New Orleans, Louisiana, August, 1989. It reviews the state of the art and presents the latest...

Hydro Development on the Huallaga River in Peru
The proposed Chaglla Hydroelectric Project, is located on the Huallaga River in Central Peru, about 300 km north east of Lima. The available gross head of 870 m and regulated flow of 58...

Glen Canyon Environmental Studies Resource Response Analysis
The primary objective of the Glen Canyon Environmental Studies is to determine how the resources of the Grand Canyon respond to the operations of Glen Canyon Dam. Two levels of analysis...

The Effect of Sedimentation on Hydro-Developments
This paper will discuss two major impacts which are the hydro construction on natural stream sedimentation and the sedimentation related problems during hydro operation. The two types...

Improving Design of Small Hydro Plants
One objective of this paper is to show why certain features of many small hydro plants have given poor operational performance or experienced expensive maintenance problems. A second objective...

Milltown Powerhouse Rehabilitation
The Milltown Powerhouse and dam are over 80 years old. The powerhouse and other structures were built in 1906 and are owned by the Montana Power Company. The plant is located on the Clark...

Determining Impacts of Sediment Using Cesium-137
Tecumseh Lake, in east-central Oklahoma, completed about 1934, has been identified by the Oklahoma Water Resource Board as a water supply critical to future development of the state. Aerial...

Stormwater Management in Virginia
In the 1986 budget bill, the Virginia General Assembly directed the Virginia Department of Conservation and Natural Resources, Division of Soil and Water Conservation, to conduct a review...

Pipe Geometry and Pipeline Bridge Wind Oscillation
Static and modal analyses of two pipeline suspension bridges owned by American Natural Resources - the Patterson Loop Aerial Crossing (PLAC) with a span of 850 feet (259 meters) and the...

Random Characteristics of Sediment-Laden Flows and the Techniques of Effective Sediment Exclusion on Dujiangyan Irrigation Project in China
The irrigation system is over 2,200 years old and discharges water at a rate of 340-740 m³/s from the Minjiang River. The average slope of the river...

Drainage Through Segara Anakan
The Lower Citanduy Irrigation Project in Central Java, Indonesia, drains through the estuary called Segara Anakan. Due to sediment accretion, the lagoon is filling. With erosion problems,...

Platte River Irrigation Development: Hydrologic Myths
Several proposed municipal and irrigation developments in Wyoming, Colorado and Nebraska could impact flows along the Platte River in central Nebraska. Opposition to these projects is...

Stable and Environmental Channel Design
The Wildcat and San Pablo Creeks Flood Control Project is located in Richmond, California. Both streams flow through a highly urbanized area, periodically overflowing their banks and causing...

Stable Channels with Loose Boundary
Recently, G. Parker suggested that the lateral transport of downstream momentum due to Reynolds stresses should be included in the momentum balance used to calculate the boundary shear...
