Modeling Contaminant Fate and Transport in Ground Water Systems
Determination of the fate and transport of contaminants in subsurface environments has been aided by recent advances in our understanding of ground water hydrodynamics and subsurface solute...
Modeling of Microbially Active Soil Columns
A soil-based microbial treatment process for on-site treatement of hazardous industrial wastewaters has been developed. The indigenous microflora of the soil are supplemented by the addition...
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...
Modeling a Water Distribution System
Problems encountered in modeling the water distribution system for the City of Norwich, NY are discussed and the procedures used to solve each problem are described. The interpretation...
A Case Study - Toms River Water Company, Toms River, New Jersey
Toms River Water Company provides water service to Dover Township, the Borough of South Toms River and portions of Berkeley Township, all in Ocean County, New Jersey. Existing supply facilities...
Complications in the Design and Analysis of Small Water Distribution Systems
The design and operation of small treatment and distribution networks can sometimes be more complicated than the design of large metropolitan systems. More often than not, the use of standard...
Water System Model Brought Improvements in System Performance
Analysis of the hydraulic conditions of a multi-pressure zone water system serving portions of two counties in a mountainous region of Southwest Virginia was performed using computerized...
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
Information is a most important resource for water resource professionals. The combination of the computer and the telephone has established a new avenue to acquire information. One directory...
Water Information Available from the U.S. Geological Survey
As a part of the Geological Survey's program of releasing water data to the public, two large-scale computerized systems are maintained. The National Water Data Storage and...
The National Ground Water Information Center Data Base
The Research Institute, Education Foundation and Publishing Company of the National Water Well Association have long been considered information central for the world's community of hydrogeologists....
Computer Applications for Real-Time Operation of Water Distribution Systems
This paper surveys the state-of-the-art in computer assisted real-time operation of water distribution systems. It first examines the reasons and justification for installing computer...
Time Series Analysis of Hourly Domestic Water Demand
Design flows for water supply and sanitary sewer systems are chosen by rules of thumb in the absence of actual data. This research develops two stochastic models of water demand by analyzing...
Water Use Forecasting and Evaluating the Effects of Conservation Measures
The City of Austin, Texas, instituted mandatory restrictions on water use during a summer drought in 1984 when water use levels beyond 150 million gallons per day stressed the city's...
Incorporating Graphics in Water Distribution Analysis
One area that has currently been receiving attention is the presentation of hydraulic analysis results utilizing computer graphics to display pipe network and pressure values in graphical...
Water Quality Modeling of Distribution Systems
Computer modeling of hydraulic conditions in distribution systems has been widely applied over the past decade for design and operation of systems. Conversely, little attention has been...
Adapting a Pipe Network Analysis Computer Program
The Metropolitan Water District of Southern California (Metropolitan) has developed a mathematical simulation model for a key portion of its distribution system. A representative portion...
Modelling Complex Water Distribution Systems
A program previously used for the analysis of hundreds of water distribution systems was successfully modified to provide the features needed for the extended simulation of large complex...
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...
