Flood Vulnerability Assessments
Definition
Flood Vulnerability Assessments use GIS to evaluate how exposed, sensitive, and adaptive communities or assets are to flooding. They integrate hazard zones, population density, socio-economic data, and critical infrastructure.
Application
Urban planners identify at-risk groups. NGOs design flood adaptation programs. Governments prioritize investment in levees or shelters. GIS calculates vulnerability indices and produces maps for risk mitigation planning.
