Monitoring Groundwater Quality in the Southwest
Monitoring groundwater quality near sources of pollution in the southwest commonly involves highly productive alluvial aquifers. Experience in monitoring in such a setting indicates that...
Irrigation and Groundwater Quality in the South
Impact of irrigation trend, water table fluctuations, crop management, and tillage systems on groundwater quantity and quality of the southeast (Alabama, Florida, Georgia, and South Carolina)...
Environmental Engineering
Over 80 of the papers presented at the 1986 National Convention on Environmental Engineering are included in this book. The major categories covered include air, noise, and radiation management,...
A Demonstration Expert System to Aid in Assessing Groundwater Contaminating Potential by Organic Chemicals
An expert systems approach to evaluating mobility and degradation of organics in soil systems is compared to conventional programming techniques. An expert system has been developed in...
Groundwater Modeling: Selection of Computing Systems
Results are presented for ten microcomputer systems evaluated with respect to system performance in solving a test case three-dimensional groundwater flow problem. The model used was the...
Global Water Issues
Five critical global water-related issues are discussed. First is the issue of climatic changes and drought. Unfortunately, the opportunities to construct major irrigation projects are...
Ground Freezing for Construction
For almost a century, freezing has been used successfully as an art to stabilize ground and control groundwater. First employed by the mining industry in Europe, it has since been widely...
Landslide Hazard Rating for the Oregon Coast Range
The landslide hazard rating system for shallow soils on steep terrain over hard sandstone has three components: ground water response to precipitation, soil shear strength (including root...
A Case History of Leakage from a Surface Impoundment
A manufacturing company constructed a 48-acre (19 hectare), unlined surface impoundment at a site in northern Texas to store wastewater. The site is underlain by unsaturated, alluvial...
Assessing Seepage at Uncontrolled Hazardous Waste Sites
This paper presents a conceptual framework for estimating the concentration of organic contaminants in a groundwater plume over time. The basis of this framework is the application of...
Municipal Refuse: Is Burning Best?
Communities are increasingly worried about polluting groundwater, and it is increasingly difficult to get permits to start new landfills. For these reasons, there is a trend back to municipal...
Mathematical Modeling of Ground Water Flow
Many numerical algorithms for ground water flow models have been published and are available in computer software packages. It is the job of the ground water specialist to select an appropriate...
Simulation of Groundwater Flows in Leaky Multi-Layered Aquifer
A newly developed computational methodology for simulating the groundwater flows in multi-layered aquifer is presented. The model is based on the finite element method following the Galerkin's...
Understanding Land and Water Resource Systems Aided by Graphics on Microcomputers
The inadequate appreciation of relations between causes of contamination and their occurrence applies to professional as well as lay individuals. Therefore, a great deal of effort is invested...
Modeling Contaminant Fate and Transport in Ground Water Systems
Determination of the fate and transport of contaminants in subsurface environments has been aided by recent advances in our understanding of ground water hydrodynamics and subsurface solute...
Two Dimensional Numerical Simulation of Subsurface Contamination by Organic Compounds - A Multiple Approach
In recent years, much attention has been focused on the migration of the soluble portion of an organic contaminant in groundwater systems. Little work, however, has been directed towards...
The National Ground Water Information Center Data Base
The Research Institute, Education Foundation and Publishing Company of the National Water Well Association have long been considered information central for the world's community of hydrogeologists....
Water Data Bank of the Hashemite Kingdom of Jordan
The Hashemite Kingdom of Jordan and the United States of America have jointly undertaken an investigation of the ground-water resources of Northern Jordan. An initial step in the investigation...
Conceptual Framework for Regression Modeling of Ground-Water Flow
The author examines the uses of ground-water flow models and which classes of use require treatment of stochastic components. He then compares traditional and stochastic procedures for...
Prior Information in the Geostatistical Approach
An overview of recent work on the geostatistical approach to the inverse problem of groundwater modeling is presented. A method which allows utilization of prior information about the...
