URBAN FLOOD DYNAMICS IN KOLKATA: EVALUATING FLOOD MAGNITUDE AND INTENSITY WITHIN THE KMC AREA

Abstract

Urban flooding has ended up a major challenge in lots of main cities around the world and Kolkata isn't an exception. The metropolis’s particular topography, coupled with rapid urbanization and negative drainage makes it especially liable to flooding. The objective of this study is to evaluate the importance and severity of city flooding in Kolkata with special attention to the jurisdiction of the Municipal Corporation. The predominant objective of this study is to better recognize flood dynamics by implementing advanced flood modelling. This study further did a comparative analysis of exclusive areas of the town. This study further offers a strategy for implementing powerful flood management by figuring out the main reasons for urban flooding. The approach uses hydraulic and GIS-based models to map flood situations below extraordinary eventualities. Data resources consist of ancient rainfall data as well as maps, and data on municipal drainage structures.The essential findings of the flood models screen great variation in the magnitude and intensity of flooding at special places in Kolkata. Research reveals areas of excessive flood threat. This also identifies crucial elements contributing to this risk which consists of insufficient drainage as well as excessive population density and low-lying geographical features. On the other hand, comparative evaluation performed on different flood control structures suggests exceptional efficiencies. Insights from this study are critical for city planners and makers of the policy. Targeted and effective flood control strategies may be developed with the help of expertise in the dynamics of urban flooding in Kolkata. The findings further emphasize the significance of improving drainage as well as implementing complete city planning and finally promoting community-based initiatives to improve the resilience of the flood. This study contributes to the improvement of broader city flood management. This study also provides valuable steering for other towns that are dealing with similar challenges. The suggestions supplied can form the basis for destiny efforts to lessen city flooding and defend vulnerable communities.
