Stochastic Modeling of Mean Areal Precipitation for Generating Synthetic Streamflows
Statistical precipitation models used as input to conceptual hydrologic models, offer an alternative mechanism for simulating streamflow. In sparsely gauged catchments, or areas where...
Stochastic Simulation of Streamflows
In order to provide a better method of generating synthetic streamflow data, a stochastic model of simulating long-term streamflows is developed. Basically, this method uses historical...
Mathematical Modeling of Ground Water Flow
Many numerical algorithms for ground water flow models have been published and are available in computer software packages. It is the job of the ground water specialist to select an appropriate...
Simulation of Groundwater Flows in Leaky Multi-Layered Aquifer
A newly developed computational methodology for simulating the groundwater flows in multi-layered aquifer is presented. The model is based on the finite element method following the Galerkin's...
Analysis of Unsaturated Flow Beneath a Landfill
Using the linearized theory of flow in unsaturated porous media, a mathematical model was developed to study the distribution and extent of unsaturated flow from a source of infiltration...
Software Authoring for the Rest of Us
Extensive use of high resolution graphics, form-oriented full screen data entry, and contextual help messages have proven to be an effective means of structuring the dialogue between the...
Accumulation of Streamflow in Complex Topography
A proposed synthetic watershed model which simulates the hydrologic process of both overland flow and interflow is presented in this paper. The synthetic model has features designed to...
Water Quantity Management for a River Regulating Agency
A river reservoir operations model (RROM) was developed to assist the Hudson River-Black River Regulating District manage flows in the Upper Hudson River Basin. The purpose of the RROM...
Modeling Contaminant Fate and Transport in Ground Water Systems
Determination of the fate and transport of contaminants in subsurface environments has been aided by recent advances in our understanding of ground water hydrodynamics and subsurface solute...
Two Dimensional Numerical Simulation of Subsurface Contamination by Organic Compounds - A Multiple Approach
In recent years, much attention has been focused on the migration of the soluble portion of an organic contaminant in groundwater systems. Little work, however, has been directed towards...
