Danang is a coastal city in the Central Region, VietNam which is considered as a sensitive area under the high risks of natural disasters and climate change. Located in downstream of Vu Gia - Thu Bon river system, Da Nang city is often inundated in flood season. Hoa Vang district is considered as the most flood damaged region in Danang City due to its location and topography. Assessing socio-economic vulnerability of floods is important in the management of natural disaster risks, from that developing solutions to mitigate the damage caused by floods. This study develops a flood vulnerability assessment method for the Hoa Vang district, Danang City based on the Geographic Information System (GIS). Through analyzing the inundation situation and local socio-economic conditions, the research has selected and developed a set of criteria to assess the flood vulnerability for the study area and presented in GIS environment. Based on the spatial analysis methods in GIS, the study has identified Flood Vulnerability Index (FVI) and generated the flood vulnerability map for Hoa Vang district, Danang city. The results from this study are important in order to propose the solutions for responding to flood hazard in Da Nang City.
