Microcomputer-Based Monthly Treatment Reporting
Massachusetts wastewater treatment plants must file monthly operating reports with the Massachusetts Division of Water Pollution Control. A microcomputer-based monthly reporting system...
Real-Time Reservoir Operations by Quadratic Programming
A quadratic programming model is developed for real-time reservoir operations. It is assumed that convex penalty functions that relates the deviations of storage levels and downstream...
Great Lakes Water Diversion: Legal Issues
This article deals with state/provincial, regional, federal and international legal issues involved with protecting Great Lakes water. First, the article describes the institutions and...
Multi-Objective Planning: Great Lakes Water Policy Issues
This paper reports upon the development of computer algorithms for multi-objective planning for Great Lakes water policy issues. Sample applications are presented for the control of phosphorus...
Legal Constraints on the Transport of Water
Legal constraints on water transport are based on legitimate concerns for protecting the future interests of the area of origin, but such constraints sometimes appear overly restrictive...
Conceptual Framework for Regression Modeling of Ground-Water Flow
The author examines the uses of ground-water flow models and which classes of use require treatment of stochastic components. He then compares traditional and stochastic procedures for...
Prior Information in the Geostatistical Approach
An overview of recent work on the geostatistical approach to the inverse problem of groundwater modeling is presented. A method which allows utilization of prior information about the...
Forecasting Water Use: A Tutorial
In spite of 4,000 years of public water supply system construction, designs have been customarily based on forecasts of future water use only during the last 100 years. Choices among available...
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...
Future Trends in Software Development
The Office of Water (OW) has set program goals of improving the productivity and technical quality of wasteload allocation modeling and water quality-based permitting in the States and...
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...
Optimization of Flood Control Projects
Project optimization analysis techniques have become indispensable tools for the design, management, and administration of flood control improvements. The increasing complexity of engineering...
Computer Usage in Obtaining Alternate Optimal Solutions for Water Resources Optimization Problems
In this paper, alternate optimal solutions of a few example linear programming problems are obtained by using a computer routine developed for the purpose. The routine is capable of generating...
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...
Optimization in Water Resources Planning
Recently developed optimization software represents significant first steps toward the application of the digital computer as a design and planning tool. This software has recently been...
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 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...
