Recent developments in micro-computers have enabled water resources engineers to utilize advanced computer methods and interactive color graphics for the analysis and planning of water...
Water Resources Applications of OCAP--Ohio's CNRIS
The Ohio Capability Analysis Program (OCAP) is a computer-based natural resources information system (CNRIS) operated since 1973 by the Ohio Department of Natural Resources. The three...
Geographic Information Systems: A Planning Tool
Geographic Information Systems provide an opportunity for water resource planners to examine potential impacts of proposed plans early in the study process. Conflicts can be identified...
Storage Projection for Reservoir Systems
Two methods are studied for determining the probability distribution of future levels of storage in a reservoir system: transient analysis and Gould's probability matrix method....
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...
Applications of Spreadsheets in Water Resources
This paper describes two applications of the spreadsheet MULTIPLAN to water resources problems. Applications include statistical analysis of water resources data and design of a stormwater...
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...
Groundwater Models: Converting Research Developments into Practical Applications
One method of bridging the gap between code developer and code applier is through separate user-friendly computer programs called preprocessors that prepare data before execution of the...
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...
Understanding Land and Water Resource Systems Aided by Graphics on Microcomputers
The inadequate appreciation of relations between causes of contamination and their occurrence applies to professional as well as lay individuals. Therefore, a great deal of effort is invested...
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...
Computer-Aided Drought Operations
A simulated drought operations exercise is conducted annually in the Washington, D. C. area. Local water supply utilities work with the Interstate Commission on the Potomac River Basin...
dBase III, Micros and Water Resource Management
The Brazos River authority is an agency of the State of Texas created to conserve and develop the surface waters of the Brazos River Basin. The Authority has initiated a project to introduce...
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...
Quantifying Social and Environmental Objectives
Over the past decade, there have been great improvements in economic and multiobjective techniques for quantifying social and environmental objectives in water resources planning. Nevertheless,...
Water Develoment Models for Contemporary Planning
A methodology for evaluating water planning alternatives was developed and applied to the Nebraska Platte River. The methodology involved a micro-computer based screening model and a multi-objective...
Getting Information Via Computer: Some Basics
