Landslide Dams
Processes, Risk, and Mitigation
Landslide dams have proved to be both interesting natural phenomena and significant hazards in many areas of the world. A few of these blockages attain heights and volumes that rival or...
Plugging into a Dam
Instruments are embedded into hundreds to dams around the world. But for instrumentation to be effective, the instruments must be read, and the data must be plotted and compared to predicted...
Rehabilitation of Blackfoot Dam In-Situ Testing and Analysis
The dam was constructed in 1909 and was recently found to require rehabilitation to enlarge the spillway and improve embankment stability against the large earthquake potential in the...
Vane Shear Testing for Staged Construction
Staged construction was used for the earthfill embankment of Birch Dam in order to compensate for low strength clays in the foundation. Sampling and testing of foundation soils verified...
New Approaches to Rehabbing Old Dams
The U.S. Bureau of Reclamation takes a look at several new ways of building old dams for maximum flooding. A labyrinth spillway was built at Ute Dam near Logan, N.M. to increase reservoir...
Controlling Sulfide Corrosion in Large Diameter Gravity Sewers (
The County Sanitation Districts of Los Angeles County undertook a major evaluation of sewer system ranging in size from 1. 22 to 3. 65 meters in diameter that transports peak wastewater...
Hydrodynamics of Earth Fill Dam Breach Erosion
An analytical model is suggested in this paper. The model is based on the continuity equation of water mass within the reservoir, a broad-crested weir discharge formula and a velocity...
Cherokee Nation Power Development at a Corps Lock and Dam
In an arrangement among the Cherokee Nation of Oklahoma, the U. S. Army Corps of Engineers and the Southwestern Power Administration, the Cherokee tribe will finance, design and construct...
Plunge Pool Energy Dissipators for Some Dams in Taiwan, ROC
This paper presents a brief description of the characteristics of the plunge pool type energy dissipators, including design considerations, hydraulic model tests, as well as the results...
Air Slot in Tunnel Spillways of Feitsui Dam
The tunnel spillway of the Feitsui Reservoir Project near Taipei has a head drop of more than 110 m, and maximum discharge of 1,500 cms. For prevention of cavitation in the tunnel, an...
Oxygenation of Releases from Richard B. Russell Dam
The oxygen injection system at the Richard B. Russell project has a continuous injection system located 1 mile upstream of the Russell damsite but also has supplemental injection capability...
A New Dam in California?Piece-of-Cake!
It initially appeared that a series of insurmountable roadblocks would prevent the City of Morro Bay from constructing a new dam and water supply reservoir on San Bernardo Creek near the...
Algorithms for Automatic Control of Diversion Dams
The application of local automatic control for the releases from a diversion dam that has intermittent river inflow is limited. For this case, it is better to install a remote monitoring...
Waterway is Public Works Landmark
The $2 billion, 234 mile Tennessee-Tombigbee Waterway connects the Tennessee River and the Gulf of Mexico at Mobile. The biggest Corps of Engineers civil-works project ever, it was created...
Record High Rise, Record Low Steel
The Bank of China, under construction in Hong Kong, will be the world's fifth tallest building. In spite of the extraordinary codes for that city�high winds, and high live...
Alternate Sewers�No Longer Alternate
The term alternate sewers means those used where neither conventional gravity sanitary sewers will suffice, nor will the septic tank/leach field system. In such situations, usually one...
Probabilistic Limit States Design of Moment-Resistant Frames Under Seismic Loading
This paper focuses on the development of a methodology for the optimal probabilistic limit states design of seismic-resistant steel frames. A mechanism for allowing the designer to include...
U.S. Bureau of Reclamation Use of Risk Analysis
The United States Bureau of Reclamation (USBR) has been using risk analysis techniques in assessments for management decisions. Before presenting USBR practice and experience, the paper...
Some Perspectives and Philosophies on Risk-Based Decision Making in Water Resources
The authors have selected four perspectives of the water resources decision problem that illustrate how formal risk-based approaches may be applied - an economic perspective, an environmental...
Impacts of Risk-Based Analysis on Current Design Practices
A summary of hydrologic design standards used by selected federal agencies for the safety evaluation of dams is presented. A computational procedure is outlined to develop hydrologic design...
