Shoreline Change Analysis For Northern Part Of The Coromandel Coast

---

The shoreline is a more dynamic, and complex region of all geological features present, as it has a mixed results of tidal, Aeolian,tectonic, and sometimes riverine activity. The shoreline change has its impact, but which is not so visible. To observe this we need a long and continuous set of data. The following project is done for a shoreline length of approximately 112 km of the North of the Coramandal Coast, as a trial and error work covering the major settlements of Puducherry, Cuddalore, and Chidambaram. Data used are derived from 1972 (from SOI Toposheets), to TM data of 2013. To derive the Shoreline from the satellite data, band ratio of Red band to IR band is done. The shorelines are digitized and saved along with the appropriate MM/DD/YYYY added to the attribute table. Digital Shoreline Analysis System (DSAS) is an extension for the ArcGIS, developed by USGS. Using the extension, transects are laid for every 50 m. Then using LINEAR REGRESSION RATE (LRR), the change for every 50 meter is analysed and stored in a table. And using the table, the Erosion and Accretion, are analysed, and understood. Total area eroded is 12.93 sq. Km, and the length is of 99.36 Km. The area of Accretion is 1.73 Km2, in a length of 22 Km.
