GIS Applications for Water Distribution Systems

Abstract

This chapter describes the geographic information system (GIS) applications for water distribution systems. The GIS applications that are covered include, development of hydraulic models, creation of thematic maps of the model output results, network simplification (skeletonization) for hydraulic modeling, estimation of node demands, estimation of node elevations, water main isolation (i.e., identifying the valves to be closed for repairing or replacing a broken water main), and delineation of pressure zones
