| Sumario: | Floods are one of the most common quasi-natural hazards in costal districts of West Bengal, India and thousands of people are affected every year. From the destruction of crop lands and buildings to the disruption of balance of the environment and the spreading of disease, floods can devastate entire regions. The risk of flood depends on the flood intensity, frequency, and duration, the vulnerability of the people, etc. The spatiality of flood risk is still insufficient at micro level study for the management of resource disasters. In consequence, the present study on ‘flood risk mapping’ is performed in Purba Medinipur (one of the coastal districts of West Bengal, India) by considering the flood frequency and vulnerability of the people as flood risk components. The frequency of floods from 2002 to 2019 is considered as a variable of assessment and twenty-five key indicators are employed to understand the vulnerability of the people of the region. From the analysis, Moyna emerges as the highest flood risk prone block and Contai-I is the least flood prone block of the district. The results can help to minimize the chances of death, injury, loss, or harm and establish a good disaster management plan against floods. |
