Abstract

Coastal change detection is critical in coastal zone application. Occurrence of tsunami on December 2004 had a drastic impact on the Tamil Nadu coast leading to changes in coastal features. Therefore accurate detection and proper monitoring of the coast is very essential to understand the coastal process and dynamics of various coastal features which will be helpful in accessing the dynamic nature of coast .This study deals with the coastal change detection of the Chennai coast few years before and after occurrence of the Tsunami using satellite imagery for effective environmental monitoring and assessment. The use of satellite imagery is advantageous over aerial photography and field survey which was previously in use as the satellite imagery provides wide coverage and multi spectral information and is cost effective which is not possible with aerial photography and field survey. In this study, LANDSAT data between 2000 and 2012 were used and change detection was performed through image processing techniques and classification algorithms. Future predictions were made using CA_Markov analysis. Results of this study showed a significant effect of Tsunami in coastal changes.
