Abstract:

Urban flooding has become a significant concern in cities worldwide. Sri Ganganagar city, located in Rajasthan's semi-arid region, is also facing this problem. Despite being known for its low annual rainfall, the city has experienced more intense monsoons in recent years, which have led to flooding. This research identifies the causes and impacts of urban flooding in Sri Ganganagar city, particularly in areas like Purani Abadi, Block Areas, Gurunanak Basti, and Ravindra Path Road, which have seen recurring instances of waterlogging. One of the major issues is the inefficiency of the city's drainage system in zones like Sadbhavna Nagar, Idgah, and the Sugar Mill Sewage Treatment Plant (STP), which struggles to cope with heavy rainfall. Additionally, rapid urbanisation in the city has increased the number of impervious surfaces, which limits the natural absorption of water and exacerbates the flooding problem. The consequences of these floods are extensive, including property damage, agricultural losses, and health risks. Floods have led to the destruction of crops, especially in the farmlands on the outskirts of the city, and it affects the livelihood of farmers. This paper also explores various risk assessment and mitigation strategies, which include improving drainage infrastructure, promoting rainwater harvesting, and fostering community engagement. By adopting these solutions, Sri Ganganagar could significantly reduce the impact of urban flooding and improve its resilience to future extreme weather events.
