Stormwater Infiltration Design Based on Rainfall Statistics and Soil Hydraulics
When comparing stormwater infiltration with other methods for stormwater drainage an appropriate design procedure is necessary. The method proposed for future Danish guidelines is based...

Fate/Transport Modeling of Immiscible LNAPL in Unsaturated Aquifers
In the past ten years since enacting CERCLA and SARA regulations there is a lack of model to adequately address the fate/transport of immiscible constituents in groundwater systems. This...

Simulation of Contaminant Migration Under Conditions of Declining Ground Water Levels
A ground water flow and transport model was developed to simulate the migration of contaminants originating from an industrial site. The development and calibration of the model were based...

Protection of a 700-GPM Municipal Well Field with a 10-GPM Barrier Well: An Update After 8 Years of Remediation
In December 1978, a municipal well field developed by the Town of Acton, Massachusetts was shut down because of contamination by 1,1-dichloroethylene. Chemicals and process wash water...

Pumping or Slurry Walls?Which Works Best for Groundwater Containment?
Results of a numerical optimization model capable of designing containment systems for sites with three-dimensional groundwater flow indicate that site hydrogeology and economic considerations...

Adjustment of Groundwater Quality Models
Groundwater quality models have been used lately in solving cases dealing with groundwater flow and pollutant transport problems. Finite element method is used in such problems and is...

Watershed-Wide Stormwater Management Planning Issues
Pennsylvania counties are responsible for basinwide stormwater management planning under the Stormwater Management Act of 1978. The predominant engineering technique employed within these...

Real-Time Dynamic Flood Routing with NWS FLDWAV Model Using Kalman Filter Updating
Dynamic flood routing model based on the four-point implicit finite-difference solution of the complete one-dimensional Saint-Venant equations of unsteady flow are inherently deterministic....

Verification of the Princeton Transport Code (PTC)
The Princeton Transport Code (PTC) is a quasi-three dimensional groundwater flow and transport code. PTC is implemented using a splitting algorithm that allows the three-dimensional solution...

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...

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...

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...

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...

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...
