Stormwater/Wastewater Management: How an Application Can Drive a GIS
Decision makers are finding that a much-needed application may be the key that drives the creation of a city- or county-wide Geographic Information System (GIS). A start-up GIS developed...
Computer Modeling as a Tool for Selecting Appropriate Air Valves for Pipeline Surge Protection
Waterhammer in water or wastewater pipelines is caused by events such as a pump power failure and can have potentially damaging effects on the pipeline or pipeline hardware. In particular,...
Water Supply Network Modeling for Infrastructure Management
The concept of a graphics-based computer package for water supply network modeling and system management is discussed. Network model input and solution data are reported via color graphics...
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
