Field-Scale Research at the TVA Columbus Groundwater Research Test Site
TVA has been conducting large-scale field experiments at their Columbus Groundwater Research test site at Columbus Air Force Base since 1983. This work has been performed in cooperation...
Global-Scale Assessment of Annual Usable Fresh Water
The quantity of fresh water on earth, although very large, is a limited quantity. A major portion of this water is the polar water that is practically unavailable for human uses. The annually...
Sophisticated Computer Tools for Water Management
Sophisticated new computer tools were applied to develop a water management plan for Nassau County, Long Island. A regional groundwater flow model and two 3-dimensional saltwater intrusion...
Design Flow Estimates for Catchments in El Dorado County, CA
A hydrologic model consisting of a rainfall-runoff model and a set of design storms is proposed for design flow calculation in El Dorado County, California. The rainfall-runoff model will...
Application of a Density-Dependent Flow and Transport Model to a Coastal Aquifer System
A three-dimensional density-dependent groundwater flow and solute transport model for a coastal region in east-central Florida is presented. The model covers an area of approximately 2900...
Verification Tests for Transport Modeling in Coastal Aquifers
The U.S. Geological Survey three dimensional Heat and Solute Transport (HST3D) model is used to simulate fate and transport of dissolved contaminant in coastal aquifers. The model originally...
Flow Augmentation in the Fenholloway River Basin
Methods to enhance water quality were examined in a north Florida river basin containing industrial wastewater effluent from a paper pulp mill. Streamflow augmentation was determined to...
Large Flood Plains Modeling by a Cell Scheme: Application to the Pantanal of Mato Grosso
The computational modeling of large flood plains presents difficulties related to the mathematical approach of the phenomenon and also to the discretization of the area under study. In...
Wastewater Treatment and Disposal System for a Vegetable Processing Facility
The authors describe the implementation of a wastewater management system designed to dispose of up to 2.1 million gallons of vegetable processing wastewater generated per day at Bellingham...
A GIS Based, Pilot Scale, Wellhead Protection Project for Southern New Mexico
The 1986 amendments to the Safe Drinking Water Act (SDWA) mandated that each state develop a wellhead protection program. Wellhead protection (WHP) means the protection of groundwater...
Strategies to Preserve Endangered Salmon in the Columbia River
The recent listing of some Snake River salmon stocks as threatened and endangered has forcefully brought Pacific Northwest resource interests together to seek solutions to preserve the...
Impact of Surge Irrigation on Furrow Water Advance
Surge irrigation was compared to continuous flow in Nebraska from 1983 - 1990. As a result of surge irrigation, advance inflow times were reduced an average of 20 percent compared to continuous...
Optimal Contaminant Plume Management with US/WELLS
A micro-computer based software package developed at Utah State University for computing optimal pumping strategies for well systems (US/WELLS) is demonstrated. US/WELLS is used to determine...
Sustained Yield of the Provo Groundwater Basin
The sustained yield of the Provo Groundwater Basin has been determined by a correlation analysis of the change in groundwater levels with the April-October stream flow at the mouth of...
Modeling the Distinction Between Regional Flow and Flow to Drains
Previous research at the Newlands Agricultural Research Center, in Fallon, Nevada, suggests that the quality of the water flowing to the 15 subsurface drain laterals in related to the...
Optimizing Conjunctive Water Use in a Dynamic Stream-Aquifer System with US/REMAX
Long-term water management planning models frequently use large time steps and must employ fairly crude assumptions (such as average climatic conditions, etc.). Managing stream aquifer...
Distribution of Stable Isotopes in Ground Water in the Rialto-Colton Basin, California
Since 1982, imported water originating in the Sierra Nevada has been used to recharge the Rialto-Colton ground-water basin, about 100 km east of Los Angeles. Stable isotopes of oxygen...
Computer Modeling Approach to Optimize Pumping for Containment of LNAPL Contamination in Unconfined Aquifers
This paper presents an approach to optimize pumping for immobilizing a floating contaminant consisting of a light non-aqueous phase liquid in an unconfined aquifer. The approach combines...
Ground Water Management in the Salt Lake Valley, Salt Lake County, Utah
The perfected and approved water right applications in Salt Lake Valley could potentially withdraw from the principal aquifer a quantity of water far greater than the annual recharge....
Ground Water Management for Wellhead Protection in a Confined to Semiconfined Aquifer, Salt Lake County, Utah
The 1986 Amendments to the Safe Drinking Water Act (SDWA) established the first nation-wide program to protect ground water resources used for public water supplies. The SDWA seeks to...
