Saving Time and Money with Archaeology
In the past 20 years, archaeology has become a necessary part of many engineering projects. However, this aspect of a project is often regarded as an obstacle in terms of costs and time....
PCB Contamination of a Mass. Harbor: Technical Challenges for a Remedial Solution
The highest priority uncontrolled site in Massachusetts, the New Bedford Harbor Superfund site, is contaminated with high concentrations of PCBs. The magnitude and nature of contamination,...
Detection of Leakage Through Subsurface Barriers Using Guided Acoustic Waves
The primary method for preventing hazardous liquid and leachates from entering the groundwater is the use of a physical barrier. These barriers are susceptible to a number of mechanisms...
Health Hazard Assessment of Waterless Remote Site Waste Management Technologies
The United States Army Construction Engineering Research Laboratory (USA-CERL) has had an ongoing research program addressing remote site waste treatment technologies. The potential for...
On-Site Containment of PCB-Contaminated Soils
A remedial investigation/design project, with subsequent post-closure monitoring, was conducted for upland areas containing PCBs at an industrial site in New Bedford, Massachusetts. A...
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...
Dredge Material Evaluation Through Harbor Characterization in New England
The New England Division (NED) of the Corps has recently developed a broad based methodology for simultaneously evaluating dredging projects that are in close proximity and which would...
Ocean Dumping at the Philadelphia Site; A Case Study
This study reviews the results of eleven years of investigation of the impact of ocean disposal of sewage sludge at the Philadelphia dumpsite. The site, located on the continental shelf...
Multidisciplinary Barge Fleeting Site-Evaluation
The U. S. Maritime Administration, in cooperation with the State of Louisiana, recently (March 1985) released a major report on barge fleeting on the Lower Mississippi River. The study...
Monitoring Environmental Impacts from Waste Disposal in the Deep Ocean
Deep ocean sites are presently being considered for the permanent disposal of wastes. Their environmental acceptability can only be assessed by an efficient and effective monitoring plan....
Long Term Deflection of Buried Plastic Sewer Pipes
During the 70's and the early 80's a research program has been carried out in Sweden regarding the long term behaviour of buried plastic pipes. The program has...
Reservoir Operation Simulation on Micro Computers
A reservoir operations planning model for a potential reservoir site on the Karadj River in Iran was developed utilizing a personal computer and a commercial spreadsheet package. The model...
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...
A Microcomputer Based Real-Time Flood Warning System
A microcomputer based real-time flood warning system is being developed as an event monitoring and early warning system for local areas. The system consists of a micro computer based central...
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...
