Coastal erosion is a natural phenomenon affecting a large number of coastal areas. The coastal zone is an area with immense geological, geomorphological and ecological interest. Monitoring and mitigation of shoreline erosion along populated coastal areas is an important task and remains a difficult goal to achieve. The coast of Karnataka state extends from Talapadi in south to Sadashivgad in north covering a distance of about 280 km. In this study, an attempt has been made to investigate the shoreline transformation along the Karnataka coast. Fair weather satellite images of LANDSAT from 1991 to 2014 with an interval of eight years were used to delineate the shoreline. A Linear Regression Rate-of-change (LRR) and an End Point Rate (EPR) statistic was carried out using Digital Shoreline Analysis System (DSAS) computer software of United States Geological Survey (USGS). Highest EPR of about 15.96 m (1991-2014) was noticed in the Ankola taluk, whereas highest LRR was about 15.5 m in Karwar, both indicating accretion. Highest erosion was noticed in Honnavar with an LRR of 19.59 m respectively and EPR of 19.95 m.
