How do you calculate coastal region elevation in coastal vulnerability index?

Answer 1

To calculate coastal region elevation in a Coastal Vulnerability Index (CVI), you typically use digital elevation models (DEMs) or topographic data to assess the height of the land above sea level. The elevation data is then categorized into different classes based on vulnerability levels, often considering factors like storm surge and sea level rise. This elevation information is integrated with other parameters, such as coastal slope and land use, to produce an overall vulnerability score for the region. The resulting index helps identify areas at higher risk of coastal hazards.
