Changes in shoreline positions of the Cuddalore coast, India, are analyzed to determine the seasonal influences of shoreline movements at a regional specific scale. Using a Digital shoreline analysis system (DSAS) tool, 73 km shoreline stretch of Cuddalore is mapped on two monsoonal seasons from January, 1991 to October, 2015. These data show that the coastline responds differently to seasonal (meteorological) forcing along the coast. An estimated difference takes place especially in the rate of changes and in the time duration in which the shoreline moves into a different position. Here changes in shoreline position are examined with respect to statistical approach viz.; End point rate (EPR) and Linear regression rate (LRR). Statistical approach results indicate that variability in shoreline influence by seasonal changes. This study demonstrates the importance of understanding the drivers of shoreline changes at a regional scale and has applications in studies concerned with coastal engineering and shoreline response to climate change.
