Abstract:

As a significance of variation in worldwide climate, an improvedoccurrence of natural vulnerabilitieslike storm flows, tsunamis and tornadoes, is projected to have intense effects on the coastal societies and ecosystems by asset of the destruction they cause during and after their occurrence. The main natural disasters that occurred recently such as the tsunami, the Thane cyclone and the Vardha cyclone were caused widespread human and financial losses along the coastal areas of Tamil Nadu. The study area is coastal zone of Chennai districts of the Tamil Nadu state, southeast coast of India. The destruction caused by these happeningsemphasized the need for susceptibility assessment to ensure better understanding of the featuresinstigating different threats and to accordinglyreduce the after- effects of the future actions. This paper determines asystematic hierarchical process based methodology to coastal vulnerability studies as adevelopment to the prevailingapproaches for susceptibility assessment. The final consequences of this study are in the practice of a coastal liability map which demonstrates the ecologically vulnerable zones. This record will give common idea about the prospect of an area to endure coastal threatsas a result of coastal destruction or sea level rise. Both predictable and remotely sensed data were used and evaluated through the exhibiting technique and with the benefit of the Remote Sensing and Geographic Information System (GIS) tools. Regions of vulnerability to littoral natural hazards of different level (high, medium, and low) are recognized.
