Abstract
Recent years, the rate of coastal erosion is considerably increased in India due to human interference and natural drivers. The coastline of the Western part of West Bengal is severely eroded. Months from June to October, as the monsoon wind affects the direction and magnitude of the waves affecting the coastline with intense erosion hotspots making zone vulnerable for the coastal community. Transportation gets open during monsoon induces erosion. Frontal beaches seaward of seawalls dissolves bringing wave breakers closer to seawalls. Abrasion at the base of seawalls accelerates slumping. In the monsoon season, overtopping of the landward of the seawall also causes high waves breaking very near to the seawalls. Many places in alongshore have been observed seawalls abruptly ended which is indicate the ‘end erosion hotspot’. The paper tries to access the drivers and processes conducting to erosion hotspots.
