Abstract:
Shore line shifts landward or the seaward due to natural or anthropogenic factors thereby changing the coastal area. The changes occur mainly due to the forces that move the sand, wind, waves, and currents. The current study presented here analyzes the shoreline of Coastal Maharashtra, to assess the change in shorelines. Landsat MSS, TM, ETM and OLI band images taken from 1978 to 2017 at an interval of about 10 years and the monthly sea level change data collected from GLOSS were taken to determine the change in the shoreline. The satellite images were being used for the change assessment and were evaluated using the digital shoreline analysis system (DSAS). The rate of shoreline change was assessed using statistical method and end point rate method. It was found that sea level change near north coast of Maharashtra is changed severely, the southern part of the Maharashtra is having less changes and the middle of the coastal Maharashtra is slightly changed from the earlier. This method proves to be useful and this enhance the quality of the change detection map.
