Development and Evaluation of Remediation Strategies by Deformation Analysis
Deformation analysis is providing guidance for the most efficient and economical seismic remedial treatments for Mormon Island Auxiliary and Sardis dams. The computer program TARA-3FL...
Seismic Stabilization of St. Joe State Park Tailings Dams
Tailings dams constructed by the `upstream' method are known to be seismically vulnerable, but field experience indicates that their seismic stability usually improves following termination...
Seismic Rehabilitation of Echo Lake Dam
Echo Lake Dam is an existing dam raising a natural lake in the Sierra Nevada in California, along the western edge of the Tahoe Basin. The dam was an embankment built with steep, hand...
Liquefaction Potential of Gravelly Soils in Dams
Gravelly soils are common components of embankment dams and their foundations. When such soils have been placed or deposited in a loose condition and are saturated, they are potentially...
Liquefaction Evaluation by Seismic Potential Procedure
Empirical procedures in common use for liquefaction evaluation employ information from a variety of sources in order to evaluate whether or not a site will undergo liquefaction. The information...
Reduction of Liquefaction Potential by Compaction Grouting at Pinopolis West Dam, SC
A previous 1984 field study and subsequently published paper (Salley et.al., 1987) described the seismic design background and evaluated the potential success of compaction grouting to...
Prestwood Lake Dam Rehabilitation
The Prestwood Lake Dam located in Hartsville, South Carolina is owned by Sonoco Products Co. It originally was a wood structure built in 1895. That structure was washed out by a hurricane...
Improving Dam Safety Using a Fin Drain
Bloemhoek Dam is an embankment dam with a maximum height of 21 m, which leaked severely after first filling in 1978. This leakage resulted in the development of `boils' over a portion...
Graham Lake Dam Remedial Measures Project
Graham Lake Dam consists of a 550-foot long earth embankment and an 80-foot long concrete spillway. Several concerns were identified during project inspections including limited spillway...
Certified Safety Assessment of Zoccolo Dam
The paper reports one of the activities carried out in the framework of a so called `certified assessment of safety' program activated by ENEL SpA - Italian National Electric Board - in...
Software Applications for Monitoring Instrumentation Data
The initial program for reducing instrumentation data, used by the Geotechnical Branch of the Louisville District Corps of Engineers, was written in 1969. This program did not allow for...
Evaluation of Rehabilitation Needs for Hydraulic-Fill Dam
This paper describes the application of analytical methodologies developed for seismic stability analysis of dams in the western U.S. (particularly the Lower San Fernando Dam in Southern...
Twin Lakes Enlargement and Rehabilitation
The Twin Lakes Enlargement and Rehabilitation Project involves an enlarged embankment replacing a two-tiered reservoir system with a single, larger-volume reservoir and new appurtenances....
Economical Solution for Flood Overtopping Potential at Senator Wash Dam
A breach analysis of North Dike for overtopping with the crest modified to the lower elevation was required to ensure the breach discharge would be adequate to prevent overtopping of Senator...
The Douglas Dam Emergency Response and Rehabilitation
Through the timely response of the Owner, the potential failure of Douglas Dam was averted, and lives and property downstream were protected. The economic losses created by loss of irrigation...
Bureau of Reclamation Experience with Innovative Solutions to Increased Design Floods
Over the last several decades advances in the hydrologist's ability to estimate floods have resulted in increases to the design floods for many existing drainages. As with other dams throughout...
Remedial Grouting at Calero Dam
This paper describes the design and construction of a remedial grout curtain to resolve a long-standing seepage condition at Calero Dam, located at the south end of the highly-populated...
Ultrafine Cement Tests and Drilling Warm Springs Dam
Ultrafine cement was chosen by the Corps of Engineers for tertiary grouting the Warm Springs Dam because of its ultrafine particle size, low settlement, medium viscosity and longevity....
Experimental Evaluation of Reservoir Bottom Remediation Material
Open trenches developed through a compacted clay liner on the bottom of a reservoir. An experimental investigation has been conducted to evaluate the feasibility of using silt-sized, nonplastic...
Geotechnical Modifications at Meeks Cabin Dam
This paper presents a summary of the geologic and geotechnical evaluation of a potential piping deficiency identified at Meeks Cabin Dam as well as description of remedial measures and/or...
