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...
Contained Dredged Material for Open Ocean Disposal
An intensive series of investigations were conducted on the sediments deposited in Craney Island, a 1012 hectare contained disposal facility in the Port of Hampton Roads, VA. Geographic...
Modeling Failure Probability of Underground Pipes
Factors influencing the performance of underground gas pipes are identified through a literature search and contacts with several utility companies. These factors are categorized as (i),...
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...
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...
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...
Urban Stormwater Investigations by the U.S. Geological Survey
Urban stormwater hydrology studies in the U. S. Geological Survey are currently focused on compilation of national data bases containing flood-peak and short time-interval rainfall, discharge...
