Coastal Vulnerability Index (CVI) prepared by INCOIS

Recently Indian National Center for Ocean Information Services (INCOIS) has prepared Coastal Vulnerability Index (CVI).

The Indian National Center for Ocean Information Services (INCOIS) has made a vulnerability assessment of the entire Indian coast at the state level. It aims to create an atlas consisting of 156 maps at 1:1, 00,000 scales for preparation of CVI.

Coastal vulnerability is a spatial concept. It identifies vulnerable individuals and locations at risk from coastal hazards.

Salient Features of Coastal Vulnerability Index (CVI):

These maps determine the coastal risks due to future sea level rise for the Indian coast. This determination is based on physical and geological parameters.

The following parameters have been used in the CVI :

  • Tidal range, wave height, coastal slope, coastal elevation, shoreline change rate, geomorphology and historically the rate of change in relative sea level.
  • In addition, a Coastal Multi-Vulnerability Vulnerability Mapping (MHVM) has also been conducted. The objective is to identify mixed hazard areas which may be submerged along with coastal areas due to extreme flood events.
