According to geographical data related to coastal flooding in Kerala, what is the approximate length of the state’s coastline along the Arabian Sea?

Kerala has an approximately 590-kilometre-long coastline along the Arabian Sea. The state has 9 out of its 14 districts located along this coastline, making it highly vulnerable to coastal hazards such as high-tide flooding and sea incursion. Because of the long coastal stretch and dense population living near the sea, a significant proportion of the state’s residents are exposed to coastal flooding risks. The long coastline, combined with tidal variations and coastal erosion, contributes to the occurrence of recurrent flooding in low-lying coastal areas.
