Instruments Detect Dam Movement During Construction
Recent attention has been given to retrofitting electrical generation facilities at existing dams. Maintaining a safe structure during construction, and accomplishing this within a budget...

Willow Creek Dam--To Be or Not To Be
In Heppner, Oregon, several alternatives for flood control were considered. A concrete gravity dam constructed using roller compaction methods was selected because of the greatly reduced...

Operation of Glen Canyon Dam Spillways--Summer 1983
Flood control at Glen Canyon Dam is provided by a 41-ft (12. 5-m) diameter tunnel spillway in each abutment. Each spillway is designed to pass 138,000 ft**3/sec (3907. 7 m**3/sec). The...

Modeling Aeration Devices for Glen Canyon Dam
The 41-ft (12. 5-m) diameter tunnel spillways at Glen Canyon Dam experienced major damage during the 1983 spring runoff. This damage was initiated by cavitation. Hydraulic model studies...

Aeration is the Solution for Sluice Cavitation Damage at Libby Dam, Montana
Cavitation has severely damaged two of the high-head flood control sluices. The damaged areas were immediately patched; however, these patches were not considered a solution to the problem....

Prediction of Dam Overtopping Due to Mudflows
The eruption of Mount St. Helens on May 18, 1980 resulted in a small mudflow into Swift reservoir, which is located immediately south of the mountain. An engineering/geologic study was...

Modeling Analysis for Management of Artificial Recharge
The objective of these groundwater and sediment modeling studies is to determine the net change in storage and potentiometric levels within the Bunker Hill Groundwater Basin resulting...

Bureau of Reclamation Hydraulic Laboratory
The Bureau of Reclamation used hydraulic models for the first time in 1930 in the laboratory of the Colorado Agriculture Experimental Station in Fort Collins, Colorado. In 1946 the Reclamation...

Superhydro
In 1986, when its six turbine/pump-generator/motor units will be in operation, the Bath County Pumped Storage Hydroelectric Project in Virginia will be the world's largest....

Itaipu, South America's Grande Dame
When fully operational, the Itaipu hydropower project, located along the Parana River between Brazil and Paraguay, will be the world's largest. In 1989, it is expected to...

Holland's Fight Against the Sea
The Netherlands have always been threatened by the sea, its Delta Region most of all. After the catastrophic floods of 1953, the Delta Plan for the strengthening of coastal defenses and...

Seismic Design of Embankments and Caverns
The papers included in this publication were presented at three symposia on seismicity and seismic design for embankment dams and underground openings. Primary topics for discussion include:...

Powerhouse
The Grand Coulee Third Powerplant Project, an extension of the Grand Coulee Dam in northeastern Washington State, has been given a 1983 ASCE OCEA Award of Merit. Located on the Columbia...

Accomplishments and Impacts of Reservoirs
Water resources have been developed by dams and diversion structures and utilized to meet the needs of civilization since ancient times. Today, water resources developments including multiple...

Earth Reinforced Dams: First in U.S.
Earth reinforcement has in recent years been applied in the restoration and construction of dams. Earth reinforcement has been used to raise dam heights, replace traditional earth embankments...

Journal of Geotechnical Engineering
Journal of Geotechnical Engineering covers the field of soil mechanics and foundations, with special emphasis on the relationship between the geologic environmental and man-made works. Computer applications...

World's First All-Rollcrete Dam
Willow Creek Dam in Oregon will be the world's first concrete gravity dam designed specifically for and exclusively by roller compaction methods. The average in-place cost...

Olmos Dam Modifications
(1981 OCEA Nominee.) The 55-year-old Olmos Dam, five and one-half miles northeast of San Antonio, Texas, required major modifications to avoid...

Recent Development in Geotechnical Engineering for Hydro Projects
Eleven of the papers presented at three sessions of the ASCE Geotechnical Engineering Division at the 1981 International Convention are included. The papers are divided into two subjects:...

Why Bother with Historic Preservation�
Two case histories are examined regarding old dams that were preserved because of their historic importance, as well as their practical use. One example concerns a dam that was exposed...
