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.
