Forecasting Demand for Urban Water
The purpose of this study is to assess current water use forecasting practice in the US Army Corps of Engineers and to recommend additional approaches which best satisfy current requirements....
Practical Water Demand Forecasting
The authors describe their experience in designing, building, and applying a water demand forecasting model for the Denver metropolitan area. In the presence of incomplete and sometimes...
EPA Supported Wasteload Allocation Models
Modeling is increasingly becoming a part of the Wasteload Allocation Process. The US EPA provides guidance, technical training and computer software in support of this program. This paper...
Tampa Bay 205J Water Quality Impact Study
Tampa Bay was identified by the State of Florida Department of Environmental Regulation (FDER) as to the top priority for an impact study using federal 205(j) grant funding. The study...
Optimizing Nonpoint Source Pollution Reduction Costs
This study demonstrates diminishing marginal returns for spending to reduce nonpoint source pollution in Hampton, Virginia. A linear optimization program selected the best combination...
Solving a State Environmental Agency Computer Maze
This discussion relates the experiences of a state environmental agency in addressing a decade of inadequate attention to the importance of computers and automated data processing to the...
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...
Numerical Modeling of Groundwater-Lake Systems
Groundwater inflows can have important effects on the chemistry and biology of a lake ecosystem. For example, studies of lakes in Northern Wisconsin documented localization of ferromanganese...
Water Quality Modeling of Key Largo Coral Reef
A numerical model called CORALSIM has been developed for the Key Largo Coral Reef National Marine Sanctuary in the Florida Keys. The model was developed as a management tool to study the...
Micro-Computer Water Develoment Screening Models
A micro-computer screening model was developed to analyze the physical and economic efficiencies of a large number of alternative options associated with a given water development project....
The Water Resources Models of the Instream Flow Group
The Instream Flow Group of the US Fish and Wildlife Service has five analytical systems designed to assist in the development of instream flow criteria for water resources projects. Models...
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...
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,...
A Post-Audit of the Potomac Eutrophication Model
An unusual, unexpected, and unpredicted event - the Potomac Algae Bloom of 1983 - prompted a post-audit examination of the primary tool being used for guiding the continuing development...
Application of Phosphorus Models to New Mexico Reservoirs
Many empirical, mass-balance phosphorus models have been developed and tested on northern, temperature lakes and previously published. Fourteen of those published models were tested on...
Hydraulic Profile Computation Using CADD
The data preparation can also be performed by directly recording onto a computer tape the aerial survey cross section ground points and the field survey work. A computer program can then...
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...
