An Expert Critiquing System to Assist in Operating a Water Supply Network
An expert 'critiquing' system is under development to assist in operating San Francisco's multi-reservoir water supply system. This computer application...
A Logical Variable Approach to Water Supply Reliability
The calculation of the reliability that water will be available at a demand point in a distribution network is complicated by the redundancy of paths from the source to the point. The...
A Water Information System for Decision Support in Design, Operation and Management of Distribution Systems
The design, operations and management of water supply and distribution systems require considerable amounts of data and data processing and analysis. What is not available to the water...
Managing Water Supply and Demand with Integrated Computer Models
Water resource planning and management has greatly benefited from the use of computer modeling. Numerous computer models have been developed to predict expected outcomes given a set of...
Optimizing Urban Ground Water Supply Systems
The cost of Pumping comprises a major part of total water operation and maintenance expenses. Most utilities attempt to keep these costs down. However, there are areas of study that may...
The State of Nevada Operational Seeding Program
Integration of the Nevada Operational Weather Modification Program into management of the region's water supply is a key element to meet the increasing demands placed on these...
Utility System Demand Forecasting Using Land Use Coefficients
In rapidly changing areas where several divergent paths of future growth are possible, there are advantages to forecasting future water demands and wastewater flows using the water and...
Public Involvement: Key to Stormwater Programs
The ultimate success of a stormwater program often depends upon the support of concerned citizens. Interaction between stormwater managers and the public is especially important in small...
Stormwater Management Policies for Two Urbanizing Communities in Western Suburban Cleveland
The cities of North Ridgeville and Avon Lake, Ohio are two western suburbs of Cleveland. The recent completion of the interstate highway, I-480, the resurgence of Lake Erie as a prime...
The Managemet of Storm Water Runoff Associated with Industrial Activity
