The ADP Problems of a River Basin Commission
The Susquehanna River Basin Commission is an independent governmental agency that recently acquired its first in-house minicomputer system. The staff usage of this system has created two...
The WSSC Integrated System Implementation Project
The software development effort conducted for the Washington Suburban Sanitary Commission began in October, 1981 and has been in process since that date. The goal of the effort is to produce...
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...
Computer Model for Wastewater Reclamation
This paper describes how an efficient computer model can be constructed and used to evaluate planning options for wastewater reclamation. The situation in the City of Scottsdale, Arizona,...
Personnel Policies for Operations Management in the Computer Age
The human factor is an essential ingredient and the key element in successful computer applications for water resources or any other field. Engineers in general, and engineering managers...
Basalt System Characterization: Inverse Technique
The Basalt Waste Isolation Project (BWIP) has been established to assess the feasibility of the Columbia River Basalt Group as a host medium for a high-level radioactive waste repository....
Digital Simulation of Flows in Hawaiian Soils
In attempting to numerically solve the nonlinear equation for flows in porous media, the Galerkin process, which bears a great similarity to direct methods of the calculus of variations,...
Risk-Cost Analysis and Spillway Design
The NRC's recent report on dam safety proposes risk cost analysis to help select among alternative spillway modifications for existing dams. This paper examines the sensitivity...
Reliability and Risk Assessment for Water Supply Systems
Analytical methods for computing the reliability of water supply systems are described and demonstrated. A case study serves to show how risk, which is the economic loss due to shortfalls,...
Reliability Analysis of Urban Water Supply
The high economic and environmental costs of large water supply projects are forcing engineers to consider not only alternative means of increasing system reliability, such as interconnections,...
Setup and Usage of Multitasking Microcomputers for Water Management Problem Solving
Software and hardware that were developed in the evolution of the microcomputer from the Altair to today's state of the art multitasking systems are discussed. The rationale...
Hydrologic Work Group System Using Distributed Task Processing
The notion behind work group systems is that a collection of co-workers, numbering from a few to a few tens of people, is the logical unit around which to build a centralized microcomputer...
Ground-Water Flow Model of Soda-Ash Waste Beds
A recent application by a steel manufacturing plant to obtain a permit for an industrial landfill located on top of abandoned soda-ash waste beds in the City of Syracuse, New York, resulted...
Groundwater Models in Choosing Water Treatment Methods
This paper presents an example of the use of groundwater models to identify the source of contamination and then design a treatment scheme. Included is a discussion of several different...
Simultaneous Withdrawal of Saline/Fresh Waters in a Stratified Aquifer
The objective of this study is to develop computational tools for simulating the flow behavior of an aquifer in response to simultaneous pumping of two stratified fluids from both sides...
Evaluating Water Policy Options by Simulation
Computer simulation models are used to predict the effects of three sample water policy decisions on selected conjunctive water use/sustained groundwater yield strategies for the Arkansas...
Dried Sludge for Fertilizer
Dried sewage sludge has been used as a fertilizer material for several decades in the United States. While sludge drying and fertilizer production is normally more costly than other municipal...
Manatee County Plans for Environmental Protection
Faced with a projected population increase of 53 percent by the year 2000, Manatee County, Florida, is protecting its water resources by developing a regional wastewater facilities program...
Development of a Demand Management Plan for Greater Boston
The Metropolitan District Commission (MDC) in Boston is preparing a long-term water supply plan for its present and potential service area. The MDC is committed to a program of water conservation...
