Summary:Abstract The rapid growth of villages and towns affecting natural drainage channels. Inundation of low-lying areas is a common phenomenon especially during rainy seasons in many localities of Narsapur town. Narsapur is considered a census town as well as a municipality situated in Medak district, Telangana State. With the increased demand for a proper drainage system, the Municipal Authorities decided to re-design the Stormwater Drainage System starting with mapping the existing road network and drains. The Narsapur town has 15 revenue wards. Considering the Topography of the town, the entire town was divided into six zones. In this study, the Central Zone of town covering 4 Wards (13, 14, 15, and 8 Partly) is considered for investigation and design of stormwater drainage systems. The entire zone is completely urbanized, and frequent inundation is observed during moderate to heavy rainfall events due to congested and improper drainage disposal system. The study is carried out in five phases viz. Mapping of Road Network, Obtaining Elevations, Mapping Drainage Network, Computation of Peak Discharge, and Design of Stormwater Drainage System. In this study, EPA-SWMM Software is used to build a Hydraulic and Hydrologic Model to analyze the existing drainage system and re-design the stormwater drains to safely discharge flood water without causing inundation in low-lying areas. To validate the results, Manning’s Flow Equation is used to compute the flow carrying capacity of drainage channels.
