Program Monitoring by Database Management
Management of the water resources programs of the Army Corps of Engineers, with its 3 billion annual budget, 27,000 employees, and decentralized organizational structure, is obviously...
Integrated Operation of the Ottawa River System
Several years ago, an integrated operating process was developed in response to specific problems on the Ottawa River. The operating process involves several public-sector organizations...
Integrated Design Methodology for Urban Stormwater Detention Facilities
The objective of this paper is to present the core of a design methodology that avoids the pitfalls of the design storm concept by using a microcomputer algorithm to estimate the long-term...
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...
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...
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...
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...
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...
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,...
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...
A Riverine Toxic Spill Model
In the event of a spill of toxic material reaching the main stem of the Potomac River, predictive information regarding its location and concentration would aid in the minimization of...
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...
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...
Building Assessment Techniques for Indoor Air Quality Evaluations
Techniques for indoor air quality evaluations are presented and discussed. The techniques presented first focus on procedures to determine effective ventilation rates and pathways of air...
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...
Ground Water Quality Assessment Using Unsaturated and Saturated Zone Models
The modeling work described here provides an assessment of the migration and fate of the pesticide aldicarb in typical Florida citrus applications with emphasis on the potential for leaching...
Modeling Aromatic Compound Transport in Groundwater
Research results are presented from an ongoing study directed at obtaining a better understanding of the factors affecting the binding characteristics of organic chemicals to ground water...
Groundwater Studies for Land Treatment Facility
A wastewater treatment facility currently under construction in Falmouth, Massachusetts, features a dual disposal method for land application of effluent. As the effluent disposal site...
