Formulating a Coastal Plain Water Quality Project
In 1988, the Soil Conservation Service in Delaware helped local sponsors prepare a detailed preauthorization planning report for water quality improvement in Indian River Bay watershed,...

Managing Water Table Management Systems for Water Quality
The purpose of this paper is to briefly summarize the results of water quality studies related to water table management conducted in North Carolina over the past 15 years. Results of...

Development and Application of a Model for Urban Use of Reclaimed Water
Water for nonpotable uses can be obtained from lesser-quality sources, and reclaimed water represents a very valuable and relatively unusual source. The planning and design process for...

Attitudes and Health Effects of Water Reuse
This paper is concerned with public attitudes toward water reuse for irrigation and with the consequences of human contact with reclaimed wastewater. Initially, attitudes are considered...

Biological Methods Petroleum Hydrocarbons Cleanup
Cleanup of the ground water and soils from hydrocarbon spills has mainly focused on air stripping and activated carbon for ground-water treatment, and vapor extraction and excavation followed...

Erosion and Sedimentation Research in ARS
The paper presents a brief history of the growth of the erosion and sedimentation research program in the Agricultural Research Service of the U.S. Department of Agriculture. Subjects...

Settling Basin Model for the Personal Computer
The SETSIZE program, models sediment deposition in a settling basin. The program can be applied to determine the length of time until dredging or cleaning is necessary or solve for an...

Cold Regions Engineering
This volume contains papers that were presented at the 5th International Cold Regions Engineering Specialty Conference, sponsored by ASCE and held in St. Paul, Minnesota, February 6-8,...

The Battle Over Burning
Prendergast examined the strategy of integrated solid waste management as a potential solution to the U.S. garbage crisis, in particular the role of resource recovery. This strategy, which...

Groundwater Monitoring Network Design Using Coupled Monte Carlo Simulation and Optimization
This paper presents a method for the design, under uncertainty, of a groundwater well network for compliance monitoring at a waste disposal site. A numerical model of contaminant transport...

Application of Hydrodynamic and Water Quality Models at a Superfund Site in Montana
The water quality model applied to the site is the EPA-supported hydrodynamic and water quality model WASP4 with a modification to enable it to better simulate riverine systems. To provide...

Climate Change and U.S. Water Resources: Results from a Study by the American Association for Advancement of Science
The time horizon of the changes that might occur is similar to the time required for planning, approval, funding, construction and economic life of such major water facilities as dams,...

Geostatistics in Estimating Chemical Residuals at a Site
Kriging with generalized covariances is used to evaluate the effectiveness of remediation and cleaning of a contaminated site. The goal is to estimate: a) the amount of total volatile...

Two-Dimensional Inter-Rill Flow Model for the Analysis of Agricultural Runoff
This paper presents a model describing the flow field for the inter-rill component of agricultural runoff. Given rainfall intensity, surface roughness, rill spacing, and longitudinal and...

Jet Injection Model Studies for the City of Los Angeles
The Hypersion Treatment Plant for the City of Los Angeles is currently undergoing an expansion project. A major component of this system is a sludge recycling system. And it is essential...

Far-Field Numerical Model Studies for Boston's New Secondary Treatment Plant Outfall Siting
By the late 1900s, Boston is scheduled to have built a new secondary treatment plant that combines the waste streams from two existing plant, and discharges the resulting liquid effluent...

Hydraulic Design Aspects of the Boston Outfall
The diffuser outfall under design for Boston must have the ability to be purged of seawater upon commissioning or following an accidental flow stoppage. The criteria governing the flushing...

Siting the New Boston Outfall: Near-Field Considerations
This paper describes a procedure applied in near-field considerations for siting the new outfall to serve the Massachusetts Water Resources Authority's (MWRA) proposed regional...

Tailwater Management for Beneficial Uses
Tailwaters can provide significant benefits for recreation, fisheries, assimilative capacity for treated wastewaters, and water supply for municipalities and industries. Development and...

Clay Joints in the Foundation of Dkhila Dam
The stability analysis performed at the beginning of construction, taking into account the shear test results of the foundation claystone showed insufficient safety factors against sliding....
