A Current Review of Experience with Asphaltic Concrete Impervious Membranes on the Upstream Slope of Earth and Rockfill Dams
At some sites where an earth or earth-rock dam is being considered, studies may indicate that the most economical and satisfactory dam would be obtained with a pervious embankment of soil...
Earthquake Considerations in Earth Dam Design
In 1963, the writer was engaged by the State of California Department of Water Resources to make a study of the influence of the hazard of earthquakes on the design of embankment type...
Piping in Earth Dams of Dispersive Clay (Paper introduced by Norman L. Ryker)
In 1971 Jim Sherard was engaged to investigate the common failure of a group of Soil Conservation Service (SCS) floodwater retarding earthfill dams built between 1957 and 1970, eleven...
Embankment Dams
James L. Sherard Contributions
This volume is dedicated to the memory of Dr. James L. Sherard, who made many contributions to embankment dam engineering. Twenty-one of his papers related to this topic were selected...
RCC at 10
Tens years after the first roller-compacted concrete (RCC) dam in the U.S.�the 169 ft high Willow Creek Dam in Oregon�was completed, the method has gained wide acceptance around the world...
Computer-Monitored Grouting
With grouting operations going on at many locations around the clock on a typical large dam-foundation project, how do you make sure that the designed mix is always being used and as-built...
Public Involvement in the Safety Monitoring of Dams, Embankments and Slopes
New methods of safety monitoring of dams, embankments and slopes require automated data acquisition, data transmission and computer based data evaluation to provide immediate safety information...
Foundation Evaluation of Barkley Dam for Seismic Analysis
An in-situ site investigation was performed at Barkley Dam, KY to gather essential information on the stratigraphy and nature of the foundation soils. From this information the site was...
B.C. Hydro's Practice for Assessing the Foundations of Existing Dams on Rock
Since the early 1980's B.C. Hydro has carried out dam safety reviews which included 33 gravity and embankment dams founded on rock. The foundations include moderately jointed,...
Innovative Design for Diversion
A conventional diversion scheme to facilitate construction of the 120 m high rockfill dam for the Beni Haroun project in Algeria would have required three 10 m diameter diversion tunnels....
Cone Penetration Testing: Cost Effective Soil Exploration
On reviewing the 1987 Part 12 Dam Safety Inspection Reports for the Wisconsin River Power Company's Petenwell and Castle Rock Dams, the Federal Energy Regulatory Commission...
Raising of King Talal Dam
The King Talal Project is located on the Zarqa River, a Jordan River tributary, in Jordan. An existing embankment dam, 100 m high, built in the mid-seventies by the Jordan Valley Authority...
Rocky Mountain Project Conceptual Design of Upper Reservoir
The 9300 acre-foot upper reservoir for the Rocky Mountain Project will be formed by an 80-ft high ring dam with a crest length of 12,800 feet. Sandstone and shale of the Pottsville formation...
Through-Flow Analysis for Rockfill Dam Stability Evaluations
Existing rockfill dams may have spillways that are not adequate to pass the current probable maximum flood (PMF), having been designed prior to the publication of the latest Hydrometeorological...
Rehabilitation of Dams, Spillways, and Hydroplants
Many older dams are in need of rehabilitation as a result of aging, deterioration, and more stringent safety standards. Concerns include deterioration of original construction materials,...
Evaluation of Embankment Erosion at TVA's Chickamauga Project
Studies were made to evaluate the extent of erosion to be expected under probable maximum flood (PMF) conditions. The erosion studies were made using the EMBANK computer program. The results...
Stepped Spillway Design for Flow Over Embankments
Many embankment dams have been identified as unable to pass their design flows without failure due to overtopping. The U.S. Bureau of Reclamation (Reclamation) is currently at the forefront...
Overtopping Flow Spillway for Baldhill Dam, Sheyenne River, North Dakota
An existing gated spillway structure for Baldhill Dam and Reservoir (Lake Ashtabula, North Dakota) is not capable of passing floods up to the probable maximum flood (PMF) without overtopping...
Overtopping Protection for A. R. Bowman Dam
Arthur R. Bowman Dam is a 245-foot-high (74.7-m) central-core rockfill dam located on the Crooked River in central Oregon. The probable maximum flood (PMF) would overtop the dam by 20...
Design of High Capacity Spillways for Ritschard Dam, Colorado
A hydraulic model investigation was conducted by the Bureau of Reclamation to assist in designing the hydraulic structures associated with Ritschard Dam. Ritschard Dam will have a labyrinth...
