Simulating Flood Exposure Due to Meteorological Extremes in GWMC
Hazard assessment and forecasting are vital for enhancing the resilience of a region. The current research communication integrates Synthetic Aperture Radar and Multispectral Remote Sensing Satellites to determine the extent and exposure of floods in Greater Warangal Municipal Corporation (GWMC). GWMC is located in the tropical semi-arid zone and is characterized by a hot and dry climate and witnesses an average annual rainfall of 863 mm. Warangal was considered under the smart city mission of India in 2015, in this process of transformation urban areas are expanding at the cost of agrarian landscapes. Assessment of land use between 2016 and 2022 in GWMC indicates the built-up spaces that have increased from 11.50% to over 20.25% promoting local climatic modifications. Changing global climate has led to meteorological extremes, in the last decade maximum intensity ~200 mm/day in August 2020 was observed in GWMC. Flood inundation ranging from 58.39 to 107.82 km2 was observed with discrete precipitation events such as ranging from 100 to 200 mm/day. Exposure maps show that 6.5 km2 to 11.4 km2 area under built-up spaces and about 50–95 km2 of cultivable landscapes are inundated due to floods. With the exiting trends in landscape and climate changes, hazard exposure tends to increase causing a negative impact on human livelihood. The analysis also aids in developing action plans, enabling appropriate policies to ensure the sustenance of society and the regional ecosystem.
