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...
Predicting Quality for Drainage Water Management
In 1982, 405 measurements of the subsurface drainage water quality parameter electrical conductivity (EC) in ds/m were collected. The data were obtained from 15 subsurface drains on 23...
Effect of Subsurface Drainage in the Lower Mississippi Valley on Surface Water Quality
Sediment and nutrient losses were measured from a subsurface drainage-runoff-erosion experiment for the years 1981 to 1984. The experiment, located near Baton Rouge, Louisiana, consisted...
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...
Ground-Water Drainage to Surface Mines Refined
Changes in seepage flux and hydraulic head (ground-water level) resulting from ground-water drainage into the first and subsequent cuts of a surface coal mine can be estimated by a technique...
Unique Considerations in the Detroit DPM Foundation Design
Foundation design for the guideway of Detroit's Downtown People Mover (DPM) was influenced by a variety of unique considerations. Severe loading conditions were created by...
Drain Maintenance in the Imperial Valley
Imperial Valley, located in the southeast corner of California is one of the most intensely irrigated areas in the world. Since Colorado River salinity is currently about 800 mg/l (1....
You Need More Than a Plumber's Helper
Maintenance of subsurface drains may be the least understood and most neglected of all maintenance activities carried out by irrigation districts. Few irrigation districts have a maintenance...
Geotechnical Innovations: Why Seldom Used in Highways?
Ground improvement methods introduced within the past decade to American geotechnical engineers offer cost savings, ease of construction and reduced construction time. Amont these innovations...
Application of Methods of Probabilistic Characterization of Soil Properties
The use of probabilistic methods to describe soil properties has many applications. One such application that has been developed is in the area of probabilistic slope stability analysis....
Grouting Rehabs Earth Dam
To accommodate increased storage needs the Pennsylvania Power & Light Company had to reactivate a fly ash basin and raise an adjacent embankment dam. However, seepage through the...
Decreases in Runoff and Sediment Yield by Drainage
Runoff and sediment yield from three small agricultural watersheds were measured during four winter rainfall seasons. Following two rainfall seasons of data collection, a subsurface drainage...
Journal of Urban Planning and Development
The Journal of Urban Planning and Development covers the application of civil engineering to such aspects of urban planning as area-wide transportation, the coordination of planning and programming of...
Joint Usage of Utility and Transportation Corridors
The problems and experiences of engineers working on transportation corridors are explored through 12 papers presented at a conference of the ASCE Pipeline Division. Corridors involve...
Water Management for Irrigation and Drainage
Proceedings of the ASCE Irrigation and Drainage Division Specialty Conference on Water Management for Irrigation and Damage, held in Reno, Nevada, July 20-22, 1977. Sponsored by the Irrigation...
Filter Fabrics: Growing Use in Road and Highway Construction
Filter fabrics are seeing increasing use in road and highway construction; and promise to see greatly expanded use in the near future. A rapidly growing use is in constructing longitudinal...
Subsurface Investigation for Design and Construction of Foundations of Buildings
This purpose of
Reinforced Earth Bridges Highway Sinkhole
Faced with an unusual sinkhole condition, the Pennsylvania Department of Transportation decided to utilize a two-way reinforced earth slab in conjunction with a subsurface grouting program...
Subsurface Exploration for Underground Excavation and Heavy Construction
Proceedings of a Specialty Conference held at New England College, Hanniker, New Hampshire, August 11-16, 1974. Sponsored by the Engineering Foundation; the Office of the Secretary, U.S....
