Its impact has adversely affects the livelihood of the coastal community. The coastal zone of India is experiencing a wide range of natural and anthropogenic pressure. This study was carried out along the Nagapattinam district of Tamil Nadu, India using multi-temporal satellite images from 1978 to 2013. The long-term coastal erosion and accretion rates have been calculated using Digital Shoreline Analysis System (DSAS). Linear regression rate (LRR) statistical method is applied to estimate the shoreline change rate. The results of the analysis shows that erosion is dominant in Sirkali, Tharangambadi, Karaikal (Puducherry State) and Nagapattinam taluks, while Thiruthuraipundi taluk is undergoing accretion. Both natural and anthropogenic processes along the coast control the erosion and accretion activities of the coastal zones. The present study demonstrates that combined use of satellite imagery and statistical methods can be a reliable method for shoreline change analysis.Read More
