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...
Groundwater Modelling
The numerical simulation of groundwater flow and transport has evolved from a technical curiosity to an established method of hydrological analysis. In this brief review the progress that...
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...
Utilization of Numerical Models in Groundwater
For many years numerical models have been used in groundwater hydrology. In a recent assessment of the availabilty and use of models, a number of problem areas were identified. Some of...
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...
Deterministic and Statistical Water Quality Modeling
An integrated methodology is presented, based on a hierarchical package of computer models ranging from simple micro-computer programs to more complex mainframe simulation, to address...
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...
