Overview of the Ohio Management Systems Evaluation Area
The Ohio Buried Valley Aquifer Management System Evaluation Area (Ohio MSEA) project is part of a regional study developed to investigate the effects of farming systems on productivity,...

Phosphorus Transport from Delaware's Rural Watershed
Phosphorus loads were estimated for 62 watersheds. Major land uses in the watersheds were cropland and forestland. Annual phosphorus loads varied from 0.42 to 1.19 kg/ha. Watersheds with...

Tributary Pollutant Effects in the Urban Stream Network
With considering unsteady flow and backwater effects, a linear water quality model is developed based on the finite difference approximation. The model is composed to two components which...

Impact of Grid Orientation on Groundwater Contaminant Transport Modeling Using the U.S.G.S. MOC Model
The U.S.G.S. method of characteristics (MOC) model was enhanced to include the input of measured contaminant concentrations, the calculation of computed and measured contaminant plume...

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...

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...

An Overview of EPRI Hydrogeochemical Code FASTCHEM^TM
The capabilities of the flow and transport modules that make up FASTCHEM are described. The linkages among the various modules that are required to achieve a hydrogeochemical analysis...

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...

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...

An Energy Approach to the Analysis of Partially-Saturated Flow
When fluid passes into or out of an aquifer, work is done at the boundaries which is partly used to change the internal energy of the system and partly to overcome resistance to flow....

Improved HSPF Infiltration Calibration Procedure with a Linked GIS
A research project for the Florida Institute of Phosphate Research sought to develop an easy-to-apply integrated surface drainage model, HSPF, and groundwater model, MODFLOW, with a geographic...

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...

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...

Prematurely Terminated Slug Tests?A Field Application
Slug tests suffer problems of non-uniqueness to a greater extent than other well tests. Alternatively, a prematurely terminated slug test (PTST) or a systematized drillstem test is proposed,...

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....

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...

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...

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....
