A Unified Optimization?Simulation Aquifer Management Model
The optimal management scenario for a groundwater production system represents a delicate balance between the water production operational schedule, which will result in the least demand...

An Optimal Parameter Estimation Model for Groundwater Resource Management
An optimal parameter estimation model is developed to identify the locations of wells, to determine pumping magnitude, and to calculate transmissivity coefficients in a confined aquifer...

Shifts in Solute Transport Direction Induced by Transient Flow
Traditionally, solute transport projections have focussed on the long-term, steady state conditions expected to prevail in a groundwater system. However, transient effects may often dominate...

Potential Role of GIS in Geotechnical Earthquake Engineering Studies at U.S. Army WES
The U.S. Army Corps of Engineers (USACE) was one of the original developers of Geographic Information Systems (GIS) and continues to be active in related research (U.S. Army Engineer Construction...

Engineering Hydrology
This proceedings, Engineering Hydrology, contains papers that were presented at the Symposium held in San Francisco, California, July 25-30,...

Dynamic Compaction of Nuclear Waste
When ponding, caused by settlement of the original soil cover over low-level nuclear waste buried at the Department of Energy's Savannah River Nuclear Plant near Aiken, S.C.,...

Cleaning Up Chromium
From 1956 to 1985, the United Chrome Products plant in Corvallis, Oregon, took a steady toll on the environment. Leaky plating tanks and the discharge of rinse water into a disposal pit...

Grouting Against Hazwaste
Grouting has only recently entered the hazardous-waste arena, mainly in the form of positive cutoff slurry walls. At an industrial landfill near Niagara Falls, N.Y., a three sided, single-line...

Predicting Effects of Subsidence on Landfill Caps
Groundwater protection at unlined, closed landfills relies upon limiting cover or cap infiltration. Depressions on closed landfills indicate infiltration from reduced runoff and loss of...

Tapping Shallow Groundwater with Horizontal Wells
In recent years, horizontal wells have become an economical water supply source alternative for many shallow water table areas in Florida. Horizontal wells typically utilize 15 to 20 cm...

Design of Transient and Steady State Drain Spacing
Drain spacings calculated by steady state or transient equations can be made equal by adjusting the design water table height used in the equations. The adjustments are not constant and...

Degradation of Ground Water by Tetrachloroethylene
Ground water from many municipal water wells in California has been degraded by tetrachloroethylene (PCE) at concentrations above the drinking water standard. Investigations conducted...

Wellfield Protection Program in Broward County, Florida
The Potable Water Wellfield Protection Program was initiated early in 1981. It examined land uses in the County, made an inventory of potential ground water pollution sources, compiled...

Case Study: Design of Groundwater Quality Monitoring Systems
This paper demonstrates the fundamental aspects of the design an implementation of state-of-the-art groundwater monitoring system, using conventional design principles. Based on experiences...

Use of D-C Resistivity to Map Saline Ground Water
It has been estimated in previous studies that 23 square miles of the Oxnard aquifer, a member of a multi-layered aquifer system beneath the Oxnard plain in Ventura County, California,...

Principles of Ground-Water Protection
Successful wellhead protection activities depend on a thorough knowledge of the ground-water flow system and an understanding of how contaminants migrate through geologic formations. Once...

Connecticut's Wellhead Protection Program
Connecticut's Wellhead Protection Program was the first in the country to receive EPA approval and remains one of the strongest programs in the nation. The program is based on comprehensive...

Oklahoma's Ground Water Protection Strategy
This report examines Oklahoma's developing ground water protection strategy in light of the national strategy. We look first at relevant federal legislation and what EPA expects of a state...

Groundwater Management in Southern Florida
A water supply plan was developed by the South Florida Water Management District (SFWMD) for Hendry County, Florida as part of the Lower West Coast Water Supply Plan. In the course of...

Ground Water Management in Arkansas
Arkansas has historically enjoyed plentiful water and has typically resolved water conflicts with case by case application of common law. As agricultural, industrial and domestic water...
