Glen Canyon Dam's Quick Fix
When the spiullways at Glen Canyon Dam were severely damaged from unexpected flooding in 1983, the Bureau of Reclamation had just 10 months to repair the tunnel spillway lining and build...
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...
Dam Pioneers Concrete Variant
The Willow Creek Dam in Oregon is the nation's first dam made entirely of roller compacted concrete. The design and construction of this dam are described and special problems...
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...
Earth Dam Seepage Control, SCS Experience
The U. S. Department of Agriculture's Soil Conservation Service (SCS) designs and administers construction of a large number of small- or medium-sized dams. SCS experience...
Seepage Control at Cochiti Dam, New Mexico
Significant design data, design assumptions and computations, and performance of the seepage control features provided at Cochiti Dam are summarized in this paper. The dam is a rolled...
Soldier Creek Dam Foundation Drainage
A possible mode of failure for Teton Dam, piping of erodible core material through unsealed foundation joints, was also concluded as being possible at Soldier Creek Dam, Utah. Evaluations...
The Use and Performance of Seepage Reduction Measures
The utilization and performance of various foundation seepage reduction measures from over 100 dams situated on pervious soils throughout the world has been reviewed. Summary discussions...
Designing and Monitoring for Seepage at Calamus Dam
Given the complex, pervious nature of the foundation for Calamus Dam, every effort has been made to incorporate design features that will reduce and control the anticipated large volumes...
Seepage in the Unsaturated Zone: A Review
This paper briefly reviews the procedures whereby the seepage rate, depth of penetration of nonreactive pollutants, and the depth of the wetting front can be calculated when the assumption...
Water Balance Approach to Prediction of Seepage from Mine Tailings Impoundments, Part I: General Water Balance Approach
The prediction of seepage from a tailings impoundment requires careful evaluation because the predictions can have significant economic impact upon designs, as well as permit stipulations...
Water Balance Approach to Prediction of Seepage From Mine Tailings Impoundments, Part II: Theoretical Aspects of Water Balance Approach to Seepage Modeling and Detailed Case History Results
Some of the most significant volumes and rates of interstitial tailings water discharge generally occurs during the initial portions of the primary consolidation process. During primary...
Seepage Control for Embankment Dams USBR Practice
The current Bureau of Reclamation approach to seepage assessment, analysis, and design for embankment dams is described. The advantages and appropriate applications for the analysis programs...
Evaluation of PVC Bottom Linear From an Existing Landfill Located in a Subtropical Climate
Remedial action to curtail leachate seepage on a sanitary landfill located in a subtropical climate included the attachment of new PVC liner to an existing 20 mil PVC liner which has been...
Underground Oil Lens Management at John F. Kennedy International Airport
Observation wells plumbed using a water surface detector and standard topographic interpolation techniques were used to establish the hydraulic gradient of the groundwater and the presence...
Seepage and Leakage from Dams and Impoundments
All major dams and impoundments are usually analyzed to determine the magnitude and location of seepage that can occur under, around or through the structure. More often than not, seepage...
Irrigation Canal Seepage and its Measurement
Reduction in seepage is one of the primary reasons used to justify investment in canal lining. Such justification depends greatly upon estimates of seepage through surface and subsurface...
Gains and Losses of Commingled Waters in a Stream
In a legal dispute in the State of Washington (Colville Confederated Tribes vs. Boyd Walton, Jr. , Farmer), it became necessary to determine the proportion of transmission losses sustained...
A Practical Means for Estimating Irrigation Canal Seepage Contribution to Agricultural Subsurface Drains
This paper describes a means for estimating canal seepage contribution to nearby agricultural subsurface drains. Canal seepage rate is influenced by a complex of many variables, but the...
Channels and Groundwater: The Hydraulic Connection
Hydraulic connection between surface and groundwater implies that surface water can seep into the ground (transmission losses from open channels, for example) and eventually become or...
