Urban surface runoff management refers to the strategies and practices used to control and manage the flow of rainwater, reduce urban flooding, enhance groundwater recharge, disaster risk management, and urban sustainability. This study focuses on improving water management practices and reducing flooding risks in urban areas by optimizing the management of surface runoff using the SWAT (Soil and Water Assessment Tool) model with Geographic Information Systems (GIS). The primary objective is to analyze water management practices and water bodies in Villupuram Municipality, evaluate surface runoff under varying urban and environmental conditions, and identify areas prone to waterlogging and urban flooding, Villupuram Municipality has a population of 141,162 in the 2011 census and covers an area of 33.13 square kilometers, divided into 42 wards. While it has historically been viewed as having low vulnerability to natural disasters, recent severe flooding incidents have highlighted significant issues in its water management strategies. The municipality's transportation infrastructure, including the Chennai-Trichy highway and the railway system, Housing, agriculture, and physical infrastructures has suffered due to unexpected flooding, emphasizing the urgent need for effective surface runoff and water management strategies to bolster resilience and sustainability. By utilizing the SWAT model alongside GIS, surface runoff can be simulated, and spatial patterns can be visualized, offering essential insights for urban planners and decision-makers to develop effective mitigation strategies. Ultimately, this research aims to enhance the resilience of Villupuram Municipality's infrastructure and promote community sustainability by tackling the challenges associated with surface runoff and improving water management practices. |
