ABSTRACT Shoreline change is regarded as a severe issue due to the changing nature of the oceans and its impact on people and land. The notion of "shoreline" refers to the rate at which the shore is eroded or accreted as a result of wave action, sea level rise, or any other risks or processes that influence the land. All natural processes are conserved in order to achieve equilibrium; the coast, as a physical feature, is always changing, and nature strives to maintain its balance. India's coastal regions are known for their diverse ecosystems, high production, and dense population, which have enhanced their importance. The present study has been conducted along the coastal areas of southern Kerala, especially Alappuzha district with the help of multi-temporal satellite images of the years 1973, 1988, 2002, 2018 and 2022. Alappuzha district which is located in the southern region of Kerala faces a significant amount of erosion leading to a greater coastal based vulnerability. The decadal changes in the shortline are evidence that the beaches are eroded at an alarming rate. The Digital Shoreline Analysis System (DSAS) technique is used for calculating the coastal erosion and accretion rates.
