Application of Storm Water Management Model to an Urban Catchment

Abstract

In the present study, Storm Water Management Model (SWMM) has been explored for the catchment of BITS Pilani-Hyderabad campus, India. The catchment has been divided into various sub-catchments and are modeled for 2006 rainfall event. The study deals with a flexible set of hydraulic modeling capabilities. In particular it is used to assess infiltration using Horton method and flow routing analysis using Dynamic wave method. The storm water network with system of pipes, channels, storage works, and diversion structures were also considered. Efforts are made to identify the critical locations of overflow. The results show that there are no nodes flooded and no overflow sections in the entire catchment. It is concluded that campus storm network system has been well planned and has sufficient carrying capacity to cater the simulated rainfall event.
