Mapping of Multi-Hazard Coastal Vulnerability

Earth System Science Organization (ESSO) - Indian National Centre for Ocean Information Services (INCOIS), Hyderabad and ESSO-Integrated Coastal and Marine Area Management (ICMAM), Chennai have carried out mapping and demarcating of multi-hazard coastal vulnerability for the states. The relative vulnerability of different coastal environments is essentially quantified at a regional to national scale using basic information on seven risk variables, viz. shoreline change rate, sea-level change rate, coastal slope, mean significant wave height, mean tidal range, coastal regional elevation and coastal geomorphology. Most of the above parameters are dynamic in nature and require a large amount of data from different sources to be acquired, analysed and processed, with an inbuilt updating mechanism.
