A STUDY ON SHORELINE CHANGES IN PARTS OF PONDICHERRY AND TAMILNADU USING REMOTE SENSING AND GIS TECHNIQUES

Coastal areas, the place where the water of the sea meet the land are indeed unique places in our global geography. Coastal zones are dynamic interfaces between land and water and are common locations of high-density development. Monitoring shoreline changes help to identify the nature and processes that caused these changes in any specific area, to assess the human impact and to plan management strategies. Remote sensing data could be used effectively to monitor the changes along the coastal zone, including shoreline with reasonable accuracy it has been taken up. The study area is the district of Pondicherry, which is the first largest among the four regions ,and it has an area of 293 km2.The study area falls in the Survey of India Topographic Map nos. of 58M/13 and 58P/16 on 1:50,000 scale. Detailed geomorphological was done based on mapping has been done using IRS P5 (2011) data and Survey of India Topographic map. In the present study, detailed coastal geomorphologic landforms of fluvial, coastal and uplands were studied.
