Optimization of a Municipal Ground Water Production System in North-Central Oklahoma
A management model is being developed to optimize the municipal groundwater production system which supplies drinking water for the City of Enid, Oklahoma. The system is comprised of one...

Conjunctive Use of Surface Water and Groundwater Management
A mathematical model is presented for conjunctive management of connected surface and groundwater systems. The groundwater module is based on the linear, two-dimensional, horizontal flow...

Groundwater Management in the Main Aquifer of High Aswaan Dam
The High Aswaan Dam reservoir replenishes a groundwater aquifer which extends on both sides of the dam lake with variable thickness. The groundwater of this aquifer is used to irrigate...

Overview and Objectives of the Macrodispersion Experiment
TVA is conducting large-scale field experiments to better define movement and dispersion of contaminants in groundwater. This will support groundwater protection by making possible more...

Second Natural-Gradient Tracer Experiment
The Tennessee Valley Authority (TVA) has begun a second large-scale groundwater field experiment at the Columbus Groundwater Research test site in Mississippi. This research is a continuation...

Measurement and Analysis of Hydraulic Conductivity Variability of a Heterogeneous Aquifer
The spatial variability of hydraulic conductivity of a shallow alluvial aquifer was investigated using borehole flowmeter measurements. The study was conducted at the site of a large-scale...

Groundwater Models and Aquifer Restoration: An Overview
In recent years, as the demand for water has increased, groundwater mining has intensified. Data on water use indicate that this trend will continue in the future, and competition is likely...

Monte Carlo Simulation of Transport from Reserve Pits
A mathematical modeling study was performed to evaluate potential health and environmental risks due to contaminant transport from exploration and production well freshwater drilling mud...

Prediction Method of Concentration Distribution of Groundwater Pollutants Using a Field Monitoring Network System
A method based on the extended Kalman filter is developed to identify the parameters of a two-dimensional stochastic convective-dispersion differential equation and to predict in real-time...

Simulation of Leachate Discharge from a Small Island into a Tidal Bay
A small island in a tidal bay was considered as a potential site for depositing large volumes of excavation material from a transportation project. The island is located in the inner part...

A Preliminary Evaluation of Model Uncertainty Given Parameter Sensitivity for Select Transport Codes
The ever-increasing use of mathematical models in groundwater management has raised concerns as to uncertainties associated with their abilities to simulate real-world pollution problems....

Risk Assessment and Management of an Oil Contaminated Aquifer: A Case History Study
This paper concerns the provision of the basic information needed for the decision-making process regarding the remedial measures leading to reutilization of an oil contaminated aquifer....

Application of Decision Analysis in Groundwater Remediation Design
The design of groundwater remediation systems involves selecting from a set of design alternatives under conditions of uncertainty. A risk-based decision analysis approach is presented...

Well and Formation Losses
For design projects in the groundwater area, a step-drawdown test is commonly used to investigate the properties of the well-aquifer systems. Higher well and formation losses are usually...

Application of Tracer Tests in Groundwater Remediation Design
Recent advances in the area of field testing for the quantification of hydraulic conductivity have resulted in improved site characterization of aquifer hydraulics and greater reliability...

Predicting Microbial Contamination of Ground Water
As a result of the drinking water standards for viruses established by the United States Environmental Protection Agency in 1985, mandatory groundwater disinfection requirements were recently...

Effects of Solute Transport Processes on In-Situ Denitrification for Nitrate Control in Ground Water
This paper discusses the effects of solute transport mechanisms on the effectiveness of biodenitrification in the subsurface environment. The only solute transport processes apparently...

The Potential Use of Genetically Engineered Microorganisms in the Remediation of Environmental Pollution
Naturally occurring microorganisms express a broad range of metabolic activities which are being successfully applied to the field of bioremediation. Genetic engineering will enhance such...

Transport Models to Simulate Nitrate Contamination
Computer models can be used to simulate groundwater flow and contaminant transport in the vadose zone, the results of which can be used as input to simulate flow and transport in the saturated...

Groundwater Modeling with GIS: An Example
The versatility and widespread usage of a geographic information system (GIS) as a hydrological modeling tool is only now showing up in the literature. In this regard, a research team...
