چکیده
Abstract The shoreline of Kalutara, Sri Lanka has become more prone to erosion because environmental changes caused by natural and anthropogenic factors including climate change. study aimed assess map the physical social vulnerability coastal in between Kalu Bolgoda River mouths Southwest Lanka. This relied on secondary data sources such as topographic, digitized, satellite maps obtained from Survey Department website United States Geological (USGS). Coastal Vulnerability Index (CVI) was calculated using only five variables namely slope, geology, soil, change (End Point Rate), Land Use Cover (LULC). On other hand, for Social Vulnerable (SVI), several socioeconomic were examined. Kalutara North Thotupala have been identified having a higher risk Physical Vulnerability. research, therefore, revealed that zone along – Panadura is vulnerable both physically socially due accelerating rate erosion. Because potential effects rising sea levels, this scenario would pose serious threat environment communities foreseeable future.
