Shoreline Change Monitoring of Karwar Coast of Karnataka, India, Using Sentinel-2 Satellite
Karnataka coastal area stretches across 320 km approximately. Karwar coast is found to be a famous tourist place and undisturbed beaches in Karnataka. Change in coastal conditions due to port activities, seasonally varying discharge and sediment transport from estuarine, and threat caused by different factors have revolved into the dynamic region; the primary aim of the study is to monitor the change in shoreline using the Sentinel-2 data for a period of 2016–2020. Sentinel-2 data is free to access and has a spatial resolution of 10 × 10 m. Multi-temporal shorelines are extracted using ArcGIS 10.4 tool and rate of change of shorelines are calculated using Digital Shoreline Analysis System tool which includes statistical approaches like linear regression rate, end point rate to identify erosion and accretion rates and comparisons are made. The results indicate that Rabindranath Tagore Beach has erosion of −17.87 m/ yr (highest value) and −0.03 m/yr (lowest value) and accretion of 3.11 m/yr (highest value) and 0.03 m/yr (lowest value). The average shoreline change rate of 6.00 m/yr (LRR) and 5.83 m/ yr (EPR). The results were found to be more precise because of the high-resolution Sentinel-2 data used.
