Comprehensive ArcGIS-Based Urban Drainage Modeling for Decision Support

Le résumé fourni par la source

Computer simulation models of urban drainage systems represent the most effective and viable means for evaluating system response to various management strategies.To be effective, these models require extensive spatial utility infrastructure data readily available from a Geographic Information System (GIS).Indeed, a utility's database contains the objects that make up the network and information about these objects.The GIS is used to link this information to the digital map.Used as a spatial database, GIS can greatly assist in various modeling and analysis applications through the development of automated tools for constructing and maintaining reliable network models of urban drainage systems.This chapter presents a comprehensive GIS-based decision support system that integrates several technologies for use in the effective management of urban stormwater collection systems.It explicitly integrates ESRI ArcGIS geospatial model with advanced hydrologic, hydraulic, and water quality simulation algorithms based on the USEPA SWMM5 urban drainage network solver, global optimization techniques based on fast messy genetic algorithms for calibration and design, automated dry weather flow generation and allocation, and automated subcatchment delineation and parameter extraction to address every facet of urban drainage infrastructure management.
