Urban Stormwater Management Policy- Linking of Urban lakes for West Part of Vadodara city

Abstract

Now days one of the most prominent activity focusing in Indian cities is the Up-gradation of the urban drainage system and utilization of Best Urban Stormwater Management Practices. Large amount of investment spent in construction of stormwater drains and adoption of Low Impact Development concepts in towns and cities to prevent flooding during heavy storms. Stormwater drains extend several kilometers across the town or city are expected to feed all the collected surface runoff into the nearest surface water body such as a lake or a river. Recently Vadodara city has declare as one of the smart cities of India but it has very big history of urban flooding due to heavy intense rainfall in short duration also flash floods takes place due to flah river Vishwamitri flowing in centre of the city. West part of the city has six lakes suffers serious issue of overflowing in monsoon season absorbing large runoff from its large impervious catchment area. Therefore, this study has been taken to interlink these lakes by Stormwater drainage system using Stormwater Management Modelling (SWMM) V5.1 software, which will reduce impact of flooding and inundation in nearby areas and will maintain sufficient water level in these lakes throughout season. This ultimately increased Stormwater absorbing capacity of lakes.
