Seepage and Transport through Anaerobic Lagoon Liners
In this chapter, the seepage and transport characteristics of lagoon liners are addressed using the soils and hydrogeology of southwest Kansas as examples....
Evaluating Seepage Losses and Liner Performance at Animal Waste Lagoons using Water Balance Methods
This chapter discusses techniques for evaluating seepage losses from existing animal waste lagoons under field conditions....
A Better Barrier
Seepage problems have troubled the Walter F. George Lock and Dam, on the Chattahoochee River, for more than 40 years. Construction of a deep positive cutoff wall is nearing completion,...
Grouting to Great Depths
Logan Martin dam on the Coosa River in Alabama has been plagued by underseepage since its construction in 1964. The karst forming the dam's foundation allows water to flow...
Dredging in the Southern Sacramento-San Joaquin Delta
The California Department of Water Resources and the United States Bureau of Reclamation are jointly conducting an environmental study and are proposing to release a draft Environmental...
Pile Wall Cuts Off Seepage (Available only in Geo/Environmental Special Issue)
An unusual cutoff wall constructed by the secant pile method succeeded in drying up seepage through the permeable strata below a saddle dam at Beaver Dam in Arkansas, owned by the U.S....
Seepage Stoppers
After 65 years of continuous operation without any major rehabilitation, the Detroit-Windsor tunnel had sprung a few leaks. Engineers used elasticized grout to stop the seepage, a material...
Application of Fuzzy Logic in Civil Engineering in Japan
In various engineering fields, many applications of fuzzy logic have been attempted, some of which have been applied for practical use. In this paper, civil engineering applications of...
Seepage Control in Dam Rehabilitation
This paper is concerned with the control of seepage problems which develop in existing dams. It is prefaced with a discussion of attitudes and experiences that have evolved over the last...
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...
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...
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...
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...
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...
General Design and Construction Considerations for Remedial Seepage Control
All earth and rock-fill dams are subject to seepage through the embankment, foundation and abutments. Methods for remedial seepage control include storage restriction, grouting, upstream...
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...
Ecohydrological Processes in Almost Flat Wetlands
In spite of their modest relief almost flat wetlands are able to maintain definite topographically driven groundwater flow systems. Large seepage areas create ecohydrological gradients...
Evaporation Pond Hydrology
Drainwater evaporation ponds are impoundment facilities designed for drainwater disposal by evaporation. In California, these ponds are typically constructed on the clay soils of the western...
Lessons Learned from Elk Creek Dam
This is the third of a series of papers published on the design and construction of Elk Creek Dam. The first paper discussed design and construction concepts to provide water tightness...
