Three-Dimensional Stability Analysis of Carpenter Dam
This paper describes the three-dimensional stability analysis of Carpenter Dam. The presence of keyed construction joints between dam monoliths at Carpenter Dam can significantly affect...
Risk Assessment: A Tool for Dam Rehabilitation Decisions
A phased approach to the dam rehabilitation decision problem is presented. The approach is based on viewing the newer dam safety evaluation approaches of incremental damage assessment...
Prediction of Embankment Dam Breaching for Hazard Assessment
Downstream hazard assessments for dams require prediction of 1) whether a breach could form, and 2) the hydraulic characteristics of the breach for use in calculations of discharge and...
Risk-Based Methodology for Seismic Rehabilitation of Earth Dams
A methodology for seismic risk analysis of earth dams is described. The procedure utilizes seismological and geotechnical inputs together with the associated uncertainties and provides...
Reliability Analysis of Navigation Structures
Methods for probabilistic stability analyses of concrete monoliths at hydraulic structures were developed and tested. Numerous analyses were performed using data from six actual structures...
Saylorville Spillway: Emergency to Service Spillway
The spillway for Saylorville Lake located on the Des Moines River, 12 miles north of the city of Des Moines, Iowa, a large metropolitan, was designed as an emergency spillway. Due to subsequent...
Some Considerations for Remedial Grouting for Seepage Control
The inadequate performance of grout curtains and the consequent need for remedial and supplementary grouting of dam foundations probably arises, in essentially all cases, from a combination...
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 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...
