Forecasting Irrigation Water Supply Using a Computer Model and Remotely Sensed Snow Cover
Improved streamflow forecasting in the Sevier River Basin is one objective of the Sevier River Water Management Study. Short-term forecasts are needed for optimum operations of irrigation...

Enhanced Multi-Dimensional Modelling of Marshes and Wetlands
This paper summarizes the verification and application of a two-dimensional finite element model capable of simulating the complex circulation characteristics in marshes and wetlands for...

Testing a Method-of-Characteristics Model of Three-Dimensional Solute Transport in Ground Water
A new three-dimensional model of solute transport in groundwater that is based on a widely used two-dimensional method of characteristics model and is coupled to a modular finite-difference...

Predicting Incipient Fluidization of Fine Sands in Unbounded Domains
Fluidization systems in the coastal environment consist of a water pumping system and a source pipe buried in or near a tidal inlet to maintain a channel or to aid in sand bypassing. If...

Sensitivity Analysis of a Ground-Water-Flow Model
A sensitivity analysis was performed on 18 hydrological factors affecting steady-state groundwater flow in the Upper Floridan aquifer near Albany, southwestern Georgia. Computations were...

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...

Monthly Conjunctive Allocation of Water Resources for Eastern Arkansas
The objective is development and use of a conjunctive water resource model as part of a hierarchical approach. In this case, this program is developed to determine the monthly allocation...

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...

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...

Slug Test: Double-Porosity, Linear Boundary, and Variable Storage Effects
The intention of this paper is to focus on three aspects of the slug test that are not as familiar as the main analysis techniques: the effects of double-porosity formations, the effects...

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...

Agricultural Chemicals in Illinois' Rural Private Wells
A statewide sampling program was undertaken to define the extent of agricultural chemicals in rural, private drinking water wells in Illinois. A stratified random approach was taken for...

Soil-Pesticide Grouping for Water Quality Management
Pesticide and soil properties contribute to changes in runoff and groundwater quality. Because pesticides have been found in runoff and ground water, those managing water quality need...

Bed Forms of Nile River
In this paper, the observed bed forms for six different reaches of the Nile River in Egypt are described. The purpose of the study is to inquire whether or not the different available...

Evaluation of Embankment Erosion at TVA's Chickamauga Project
Studies were made to evaluate the extent of erosion to be expected under probable maximum flood (PMF) conditions. The erosion studies were made using the EMBANK computer program. The results...
