Shoreline Change study along the Coast of Cuddalore, Tamil Nadu, South India

In the present study, an attempt has been made to map shoreline changes of Cuddalore coast, Tamil Nadu, South India using remote sensing and GIS. The shoreline is rapidly changing land forms in the coastal area. In coastal GIS and its deliver the more evidence’s about on coastal land form dynamics. Therefore, accurate detection and continuous monitoring is very important to realize the coastal processes and dynamics of various coastal features. This study is to investigate the shoreline change along the coast of Cuddalore Tamil Nadu, South India, using ArcGIS and IRS and LANDSAT data. (2000 – 2012) are used to extract the shoreline and the data are handled by using the ERADAS IMAGE software and examined by ArcGIS 9.3 workstation. The study area reveals particular areas have been undergone erosion and accretion. Lesser changes could be noticed along the northern and southern part of the coast. Some necessary measures have been taken by the government for the coastal zone management. The ecological importance of the mangroves, afforestation of mangroves should be increased in the study area to reduce the wave height considerably during extreme events, such as major storms and tsunami and protect the coast from erosion. The coastal area erosion and deposition have been increased in some areas along the coast. The study proves that, geospatial science has got immersive applications of changes like this.
