Storm water Drainage Network Design and GIS mapping for emerging smart city of Gujarat-Dahod

Abstract

In the absence of proper stormwater drainage systems, the major issue that arise in the developed areas is the accumulation of high volume of stormwater resulting into flooding. Proper stormwater drainage is essential from environmental, economical, aesthetic and social aspect. Data has been collected for the city of Dahod. Rainfall data of the past 20 data has been collected from State Water Data Center along with Digital Elevation Model. The collected data have been analyzed using various techniques in Geographic Information Systems and is further utilized in giving a proposal for Stormwater drainage network using StormCAD for efficient disposal of Stormwater. The model created can be adopted in various different geographic locations to construct and design stormwater drainage network efficiently and economically due to the nature of QGIS and DEM.
