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...
Implementing a Groundwater Control Board
Memphis, Tennessee, situated on the banks of the Mississippi river, has never utilized this vast resource for water supply. Instead, Artesian wells have supplied the Memphis, Tennessee...
World Bank's Role in Global Water and Related Environmental Issues
The World Bank provides loans and technical assistance to developing countries for improvement of the physical and economic well-being of the people. A major portion of its lending is...
Role of State Department in Environmental Issues
The Department of State plays a key role in resolving international environmental issues. This paper describes how the Department is organized to deal with environmental concerns, discusses...
Hydrologic Criteria: NPS Water Quality Assessment
This paper summarizes the authors deliberations and findings regarding selection of hydrologic conditions suitable for the evaluation of the water quality impacts of nonpoint sources (NPSs)...
Must the Courts Resolve All Our Conflicts?
In June 1981, the Maryland Office of Environmental Programs issued a draft 'nutrient control strategy' for the Patuxent River as a first step in preparing a regional...
Water Quality Management During Low-Flow Periods: A Systems Analysis Approach
Water quality objectives may require water managers to consider deviations from original project purposes to provide downstream water quality maintenance during low-flow periods. The decision...
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...
Modeling of Contaminant Transport in Rivers with Emphasis on the Interaction with Movable Boundaries
The transport of dissolved and absorbed pollutants is simulated by a one-dimensional convection-diffusion model which particularly accounts for the exchange processes at the river bed...
100 Years of Sedimentation Study by the USGS
On January 15, 1889, the U.S. Geological Survey began collecting sediment data on the Rio Grande at Embudo, New Mexico. During the past 100 years the U.S. Geological Survey's...
Water Resources Planning and Management
The proceedings of the 16th annual Water Resources Planning and Management Conference, which was held on May 22-24, Sacramento, CA, consists of four page extended abstracts for about 200...
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...
Top Projects for 1989
Transportation-related projects, most notably bridges, dominate the 1989 OCEA projects, but each of the 11 improved the quality of life of people in the community without harming the environment....
A Frictional Resistance Model for the Analysis of Non-Point Source Pollution Processes
This study experimentally investigated the effect of a permeable bed for steady, laminar and smooth turbulent free surface flow on the Darcy-Weisbach friction factor. Flow velocities and...
Effects on Reservoir Water Quality Caused by Changes in Inflow Plume Hydrodynamics
In this paper, the effects of environmental changes on the hydrodynamic behavior of the Las Vegas Wash inflow into Lake Mead are discussed from the view-point of water quality. It is hypothesized...
CORMIX1: Expert System for Mixing Zone Analysis of Pollutant Discharges Into the Water Environment
The Cornell Mixing Zone Expert System (CORMIX) is an integrated software package for the analysis, prediction, and design of aqueous toxic or conventional pollutant discharges into watercourses....
Water Quality Monitoring of Highway Construction
The primary objective of water quality monitoring, as it relates to highway construction, is to obtain quantitative information to ensure that runoff from the construction site does not...
Greenhouse Effect on Estuarine Saltwater Intrusion
A report by the British Department of the Environment calls for research into the effect of a rise in world temperatures on sea levels. Model studies should investigate changes in the...
Identifying Temporal Change in the Spatial Correlation of Regional Groundwater Contamination
An approach for estimating the semivariogram based on the jackknife method can be used in connection with standard confidence procedures to set closely approximate confidence limits on...
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...
