GIS Based Urban Drainage Modelling.
This chapter presents a Geographic Information System (GIS) based urban drainage hydraulic model. The model was used to solve the flooding and pollution problems associated with inadequate urban drainage for a drainage area in Huntington, West Virginia. The GIS analysis was conducted in PC ARC/INFO, a GIS software from Environmental Systems Research Institute (ESRI). Hydraulic modelling was done using the Storm Water Management Model (SWMM), a comprehensive rainfall-runoff simulation model from the U.S. Environmental Protection Agency (EPA). The benefits of using a graphical interface to facilitate the modelling are illustrated.
