Coastal erosion vulnerability assessment along the eastern coast of Bangladesh using geospatial techniques

Coastal zones are physically, socially, and economically important. However, many coastal zones are highly vulnerable to coastal erosion due to high population density, tourist attractions, developed economy, and lowland. Erosion vulnerability assessment with limited criteria and components cannot provide detailed and accurate results. Therefore, an integrated vulnerability assessment of coastal erosion is essential to produce detailed and accurate erosion vulnerability information to support mitigation strategies. This study aims to prepare an integrated coastal erosion vulnerability approach using geospatial techniques and examine the pattern of vulnerability to coastal erosion effects in the eastern coastal region of Bangladesh. Thirteen spatial criteria under two components of vulnerability, namely, physical and socio-economic vulnerability, were assessed. These criteria were weighted on the basis of the…
