Uplift Pressures in Existing Concrete Dams
This paper is a brief summary of a report of the same title prepared for the Electric Power Research Institute (EPRI) as part of its program to study ways to economically improve dam safety....
Effect of Seepage in Cracks in Older Gravity Dams
One of the many problems encountered by dam designers is that of estimating uplift pressures in cracks within older concrete dams. As part of ongoing research, we are investigating this...
Concrete Lining the Coachella Canal in the Wet
The Use of Polyurethane Grouts and Grout Tubes
Most polyurethane grouts used for seepage control are one-component, and water activated. They are prepolymers of a polyisocyanate with a polyol. Some of the polyurethane grouts use an...
Design of Seepage Control Systems for RCC Dams
As the reservoirs of the first generation of roller compacted concrete (RCC) dams have been filled, several have exhibited significant amounts of seepage, a fact that has been of concern...
An Expert System for Diagnosis and Treatment of Dam Seepage Problems
Evaluation of Reservoir Seepage in Karst Topography
Areas where seepage is likely to occur in the karst environment of the proposed West County Reservoir, Roanoke County, Virginia have been indentified. Solutioning exists in the form of...
Heave of Shallow Excavations in Slickensided Clay
Modeling the Influence of Groundwater on Slope Stability
Dam Seepage Analysis Using Artificial Intelligence
The paper discusses an interactive advanced decision support system (ADSS) which is being applied to analyzing seepage from embankment dams. The development of a prototype knowledge base,...
Seepage Effects on Sedimentation of Fly Ash Slurry
The Disaster of Stava/Northern Italy
Stopping Seepage
The Navajo Dam in New Mexico has major seepage problems. The Bureau of Reclamation, which owns the Dam, conducted studies, verified by outside consultants, concluding that the combination...
An Uncertainty Analysis Methodology Applied to Sheetpile Cofferdam Design
The input data to numerical simulation models is often uncertain, and, consequently, model predictions may be uncertain. Such uncertainties are often treated by Monte Carlo techniques....
Factors Influencing Conveyance Efficiency
Losses from a water distribution system are inadequately defined by reference to only the gross conveyance efficiency (Ec) of the system. The various unavoidable and avoidable losses that...
Laboratory and Field Determined Seepage (
In order to obtain quick and reliable estimates of seepage, an attempt was made to establish a relationship between one or more of the properties of concrete canal lining and seepage....
Seepage/Drainage Investigation Colusa County California
High groundwater in the late winter months saturates the soil profile, causing damage to both crops and soil. Sustained water logging severely damages or destroys orchards. It has generally...
Design of Seepage Fields for Stormwater Disposal
Stricker Pond is a shallow twenty-acre kettle hole pond in south-central Wisconsin. The pond receives runoff from a closed watershed that is rapidly undergoing low density residential...
Seepage Studies Using Tracers and the Self Potential Test
Mill Creek Dam, a homogeneous silt structure resting on a conglomerate foundation, has experienced severe 'seepage since its construction in 1941. In 1981, a concrete cutoff...
Embankment Seepage Control Design and Construction
For seepage control features of embankment dams, design criteria and construction practice is reviewed as it is reflected in the experience of the U. S. Army Corps of Engineers. The generally...
