Great Lakes Levels: Toward Systematic Decision Making
The International Joint Commission (IJC) has authority given by the governments of Canada and the United States to use existing works to regulate the lakes system according to agreed-to...
Leachate Flow Through Landfills
The problem of estimating the amount of leachate generated in a landfill site is of significance in the assessment of potential environmental impacts. Although there are a variety of regulations...
A Linear Dynamic Programming Model for the Optimal Allocation of Water in Groundwater Dependent Areas
The purpose of this paper is to describe an efficient computer-aided planning method using linear and dynamic programming together with a finite difference groundwater model to determine...
A Ground Water Modeling Effort to Simulate the Results of An Aquifer Restoration Scheme
A ground water model using the IBM PC version of the USGS MODFLOW code was constructed to simulate the ground water flow beneath an industrial site in the central Midwest. A detailed three-dimensional...
Application of a GIS to a Ground Water Classification System
New more effective methods of ground water management are being developed by the New Jersey Department of Environmental Protection (NJDEP) including an anticipatory conceptual State ground...
TRUMPET: A TR20plus Watershed Model?Version 1.04
The TRUMPET watershed model is a microcomputer application which expands upon the widely used SCS TR20 hydrology computer program by providing user-friendly, interactive input and file...
Comparison of Two Methods for Modeling Urban Runoff
The techniques currently available for modeling urban runoff can generally be grouped into discrete and lumped system approaches. The storm water management model (SWMM) provides procedures...
Daily Water Budget Model for Water Resources Management
A daily water budget model has been developed and tested for the Clinch and Powell watersheds located in SW Virginia and NE Tennessee. The model integrates available data and simulates...
Water Conservation and Floodplain Regulation at Barrett Dam?San Diego, CA
Barrett Dam is owned and operated by the City of San Diego, California. This paper describes the response of the dam to heavy storms that occurred in Southern California in 1980. Computer-generated...
Water Demand Forecast Uncertainty
This paper examines the effect of water demand forecast uncertainty on the operation of a city's water supply system. It is based on a number of years experience the author...
Use of Stormwater Models to Optimize the Performance of a Regional Stormwater Detention System
implications of stormwater models to develop a regional detention basin master plan for Fairfax County, Virginia are described. Following the selection of candidate sites and detention...
Underground Storage in Urban Stormwater Management
The use of underground pipe detention basins is discussed. These basins mitigate the frequency of localized flooding and sewer surcharging by effectively increasing the flow capacity of...
Resolving a Groundwater Conflict in Colorado
In 1985, the City of Lakewood, Colorado, submitted applications for permits to drill 20 wells in the Arapahoe Aquifer with the intent of appropriating 4300 acre-feet annually for eventual...
Administration of Water in the 21st Century in Accordance with the Appropriation Doctrine
In accordance with the appropriation doctrine it appears straightforward to distribute water during below-average supply, 'first in time of use, first in right of use'....
BMPs for Urban Stormwater Management in Virginia
This paper presents discussions on applying best management practices (BMPs) in Virginia as part of the Chesapeake Bay clean up program and future information needs....
Continuous Drainage System Modeling of Jones Run
A generalized package of hydrologic and hydraulic models has been developed for the quantitative analysis of watersheds and drainage networks. The package is called ODWAP (the Old Dominion...
Stormwater Management in Virginia
In the 1986 budget bill, the Virginia General Assembly directed the Virginia Department of Conservation and Natural Resources, Division of Soil and Water Conservation, to conduct a review...
GWPATH: Ground-Water Flow Path Analysis
GWPATH is an interactive software package for estimating horizontal fluid pathlines and travel time in fully saturated groundwater flow domains. GWPATH was developed for the IBM PC-AT...
A Vectorized Polynomial Preconditioned Conjugate Gradient Solver Package for the USGS 3-D Ground-Water Model
A vectorized polynomial preconditioned conjugate gradient (PPCG) numerical algorithm is presented as an additional solver package interfaced with the Modular Three-Dimensional Finite Difference...
Small Diameter Gravity and Pressure Sewers
In communities with low population density or physical features that make conventional gravity sewers inordinately expensive, alternative sewer technologies can be significantly lower...
