Pitfalls Associated with the Assumption of a Constant Partition Coefficient in Modeling Sorbing Solute Transport Through the Subsurface
This paper presents several case studies where the estimation of the adsorption coefficient, Kd, by means of the Koc-foc...
Modeling of Reactive Chemical Transport of Leachates from a Utility Fly-Ash Disposal Site
Fly ash from fossil-fuel power plants is commonly slurried and pumped to disposal sites. The utility industry is interested in finding out whether any hazardous constituents might leach...
2-D Groundwater Transport of Reactive Solutes with Competitive Adsorption
This paper presents a 2-D model, with applications, for the groundwater transport with competitive adsorption of a metal, a ligand and a complex. The model, called METLI, computes advection-dominated...
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...
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...
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...
Buoyant, Miscible Plume in Heterogeneous Aquifer
A three-dimensional, particle tracking scheme is used to compute the trajectory of and spread about the centroid of a mass slug added to steady flow through an infinite aquifer with an...
Sediment Transport Measurements in the Nile River at Bani Mazar
Measurements of sediment transport on the Nile River were conducted at Bani Mazar (200 km South of Cairo) during high and low water stages. Bed-load and suspended-load transport rates...
Application of Stable Channel Design Method
Systematic stable channel design methods are currently being developed by the US Army Engineer Waterways Experiment Station for use in the planning stages of local flood control projects....
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...
