Coastal erosion, Accretion, Remote Sensing, GIS, Management


Coastal studies is a wide field, which mainly indicates the changes in the earth surface easily and clearly due to the actions that take place in its surface and subsurface rapidly due to various parameters like wind, wave, tides, eruption, faulting etc. All these help in, identifying the proper changes that take place in the area frequently. In the present study, the erosion and depositional activities that happened along the coastline from Thoothukudi to Vembar was studied in detail with the help of Geology, Geomorphology and Bathymetry and the Digital Shoreline Change Analysis technique and the shoreline changes for a time period of 22 years in the study area. From the field study the area under high erosion was noted and the area that has undergone deposition was determined. The area where remedial measures has to be taken is been noted and the places where vegetation has to be raised were also identified. Remedial measures include beach nourishment and dune grass planting in the study are suitable for the reduction of the erosion in the place. From the study, it is been confirmed that erosion occurs at a higher rate when compared with accretion in the area.
