INCOIS carries out coastal vulnerability assessment

What is the news?

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

What is the Coastal Vulnerability Index (CVI)?

INCOIS has carried out a coastal vulnerability assessment for the entire Indian coast at States level. It has brought out an Atlas comprising 156 maps on 1:1,00,000 scales to prepare a Coastal Vulnerability Index (CVI).

The atlas determines the coastal risks due to future sea-level rise based on the physical and geological parameters for the Indian coast.

The parameters used are: a) Tidal range b) Wave height c) Coastal slope d) Coastal elevation e) Shoreline change rate f) Geomorphology and g) Historical rate of relative sea-level change.

This assessment can be useful information for coastal disaster management and building resilient coastal communities.

What is a Coastal Multi-Hazard Vulnerability Mapping?

A coastal Multi-Hazard Vulnerability Mapping (MHVM) was carried out using parameters like sea level change rate, shoreline change rate, high-resolution coastal elevation, extreme water level from tide gauges and their return periods.

The mapping was carried for the entire mainland of India on a 1:25000 scale.

The maps depict coastal low-lying areas exposed to the coastal inundation.
