Application of Digital Image Processing in Morphological Analysis of Geotextiles
Geotextile filters are rapidly replacing graded granular filters in dams, landfills, edge drains, and retaining walls. The design of these filters requires morphological information about...

Seismic Remediation for Earth Dams
Over the last 30 years or so, new analysis methods and case histories of dam performance in earthquakes have significantly changed our understanding of the severity of the earthquake hazard...
Coolidge Dam Abutment Stability and Stabilization
This paper focuses on left abutment stability assessments and stabilization measures at Coolidge Dam, Arizona. Initial assessment of abutment stability was based on limited rock strength...
The Coyote Dam Outlet Works Replacement Project: Hazard Reduction
The Santa Clara Valley Water District's Coyote Dam faced three major concerns: siltation of the existing outlet; a fault that crosses the existing outlet pipe; and the dam toe and the...
Future Urbanization Effects on Occoquan Dam PMF
The Fairfax County Water Authority's Occoquan dam, in northern Virginia, are being anchored at a cost of about $2 million. The reason is to increase stability due to an increased PMF estimate...
Embankment Dam Safety
Procedures for identification and evaluation of conditions which can lead to catastrophic dam failure through either piping or deep seated instability of the downstream surface are presented....
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...
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...
Seismic Stability Modification Requirements for Pineview Dam
Pineview Dam is located 8 km upstream from Ogden, Utah, and about 8 km from the Wasatch Fault Zone. Preconstruction information and construction records available at the outset of the...
Liquefaction Potential Leads to Dam Reconstruction
Results of a visual inspection of the Dundee Dam conducted in 1982 revealed the presence of seepage on the downstream toe of the left embankment. Subsequent subsurface explorations and...
Seismic Rehabilitation of Sardis Dam
Extensive subsurface investigation of the embankment dam revealed the existence of a weak layer of silt and soft clay in the original topstratum clay underlaying the upstream shell of...
Evaluation and Rehabilitation of Relief Wells
The U.S. Army Engineer District, Vicksburg has developed an expedient method of rehabilitating arrays of large numbers of gravity flowing relief wells located along the toe of dams using...
Design Considerations for Raising Existing Dams for Increased Storage
While a number of new dams have been constructed in the United States and other countries in recent years, much of the construction activity related to dams has involved the raising of...
The Dam Safety Process
A safe dam is one which performs its intended functions without imposing unacceptable risks to public safety, property, and welfare by its presence. Ensuring the safety of a dam requires...
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...
The Stabilization of Concrete Dams by Post-Tensioned Rock Anchorages: The State of American Practice
Permanent post-tensioned rock anchorages have been used for over twenty years in America to stabilize existing concrete dams and their appurtenant structures. This paper provides a state...
