Computer Modeling of Distribution System Water Quality
The WADSY-Q computer program was developed as a tool to analyze water quality patterns in water distribution systems with multiple sources. The program calculates the concentrations of...
Water Data Bank of the Hashemite Kingdom of Jordan
The Hashemite Kingdom of Jordan and the United States of America have jointly undertaken an investigation of the ground-water resources of Northern Jordan. An initial step in the investigation...
Hydrological Database Management
Development of hydrological database management is investigated in this study. Lotus 1-2-3, a commercially available database, which makes use of spreadsheet has been used to solve a broad...
Automated Data Collection for Reservoir Regulation
Various regulation changes in the Lake Winnebago basin have been proposed regarding the protection of wetlands and assurance of adequate outflows for water quality. To implement these...
Optimal Operation of a System of Lakes for Quality and Quantity
A methodology is presented combining simulation and optimization techniques for determining operation strategies for a system of lakes in the presence of quality and quantity constraints....
Modeling Water Resources Systems for Water Quality
A reservoir system analysis computer model has been recently developed with the capability to simulate up to 10 reservoirs, 30 control points and 8 water quality parameters. With this...
Conceptual Framework for Regression Modeling of Ground-Water Flow
The author examines the uses of ground-water flow models and which classes of use require treatment of stochastic components. He then compares traditional and stochastic procedures for...
Prior Information in the Geostatistical Approach
An overview of recent work on the geostatistical approach to the inverse problem of groundwater modeling is presented. A method which allows utilization of prior information about the...
EPA Supported Wasteload Allocation Models
Modeling is increasingly becoming a part of the Wasteload Allocation Process. The US EPA provides guidance, technical training and computer software in support of this program. This paper...
Future Trends in Software Development
The Office of Water (OW) has set program goals of improving the productivity and technical quality of wasteload allocation modeling and water quality-based permitting in the States and...
Tampa Bay 205J Water Quality Impact Study
Tampa Bay was identified by the State of Florida Department of Environmental Regulation (FDER) as to the top priority for an impact study using federal 205(j) grant funding. The study...
Groundwater Modelling
The numerical simulation of groundwater flow and transport has evolved from a technical curiosity to an established method of hydrological analysis. In this brief review the progress that...
Numerical Modeling of Groundwater-Lake Systems
Groundwater inflows can have important effects on the chemistry and biology of a lake ecosystem. For example, studies of lakes in Northern Wisconsin documented localization of ferromanganese...
Utilization of Numerical Models in Groundwater
For many years numerical models have been used in groundwater hydrology. In a recent assessment of the availabilty and use of models, a number of problem areas were identified. Some of...
Risk Assessment for Groundwater Contamination: I
This paper constitutes Part I of a two-part article. Both parts focus on the risk assessment and management process in terms of the ever-present problem of groundwater contamination and...
Risk Assessment for Groundwater Contamination: II
This paper constitutes Part II of a two-part article. Both parts focus on the risk assessment and management process in terms of the ever-present problem of groundwater contamination and...
Deterministic and Statistical Water Quality Modeling
An integrated methodology is presented, based on a hierarchical package of computer models ranging from simple micro-computer programs to more complex mainframe simulation, to address...
Water Quality Modeling of Key Largo Coral Reef
A numerical model called CORALSIM has been developed for the Key Largo Coral Reef National Marine Sanctuary in the Florida Keys. The model was developed as a management tool to study the...
The Water Resources Models of the Instream Flow Group
The Instream Flow Group of the US Fish and Wildlife Service has five analytical systems designed to assist in the development of instream flow criteria for water resources projects. Models...
Digital Simulation of Flows in Hawaiian Soils
