Eastern coast of Sri Lanka faces periodic cyclones, storm surges and floods that cause realignment and consequent coastline changes in addition to the anthropogenic activities. This study was aimed in the entire coastal area of Batticaloa district (eastern coast) to look at the coastal morphology and its changes over a period of 12 years from January 2005. About 67% of the coastal belts were subjected to accretion and about 53% subjected to erosion. The 2004 tsunami made mega impact on the east-coast and changed the shapes and structures of the coasts in different ways at various scales: about 76% of the coastal belt has been damaged, 23% less damaged and 1% fully damaged. The Batticaloa coast subjected to many human activities and its morphology has been changed due to Casuarina plantation, man-made coastal openings between estuary and sea, tourism and related activities.
