New Approach to Assess Multi-Scale Coastal Landscape Vulnerability to Erosion in Tropical Storms in Vietnam

The increase of coastal erosion due to intense tropical storms and unsustainable urban development in Vietnam demands vulnerability assessments at different research scales. This study proposes (1) a new approach classify coastlines (2) suitable criteria evaluate index (CVI) national regional/local At the scale, Vietnamese coastline was separated into 72 cells from 8 coast types based on natural features, whereas Center region 495 41 both socio-economic features. were carried out by using 17 related local land use/cover, socio-economic, datasets. Some simplified variables for CVI calculation scale replaced quantitative scales, particularly geomorphology variables. As result, more than 20% Vietnam’s has high values, significantly 350 km coasts center part. landscapes with residential tourism lands close beaches without protection forests have been strongly affected storms’ erosion. is cost-effective data use processing ideal identifying evaluating
