The Impact of the October 17, 1989 Loma Prieta Earthquake on Coastal Bluffs and Implications for Land Use Planning
The October 17, 1989, Loma Prieta earthquake caused bluff failure along 100 miles of coastline between San Francisco and central Monterey Bay in a variety of rock types and slope conditions....
Foundations and Breakaway Walls of Small Coastal Buildings in Hurricane Hugo
After Hurricane Hugo a survey of damage to small, coastal buildings was conducted in North and South Carolina. The performance of elevated foundations, breakaway walls and foundation cross...
Geotechnical Failure of Revetments
A calculation method is developed to analyse the stability of a granular subsoil underneath a revetment under wave attack. This method leads to a minimum revetment weight per square meter...
Numerical Modelling of Lower Lias Rock Failures in the Coastal Cliffs of South Wales
A model has been developed to evaluate slope failure in the interbedded limestone and mudstone Lower Lias series which outcrop for some 30 km in coastal South Wales. Computer simulation...
Evaluation of an Eicher Fish Diversion Screen at Elwha Dam
In the spring of 1990, the Electric Power Research Institute (EPRI) initiated testing of an inclined fish screen installed in a 9-foot diameter penstock at the Elwha Hydroelectric Project...
Evaluation of Alternatives for Providing Minimum Flows Below TVA's South Holston Dam
TVA is in the initial phases of a project to provide minimum flows in the South Fork Holston River below South Holston Dam. The purposes of the minimum flows at South Holston are to enhance...
Harvest Facility Protects and Improves Fishery
By constructing a trap and transfer/harvest facility to control anadromous fish migration, the trout fishery on the Boardman River was protected and the salmon fishery was improved. The...
