Abstract
Central Vietnam is highly vulnerable to flood disasters. Due to the trend of increased weather extremes, the vulnerability keeps to be further exacerbated causing high risk of casualties and damages. Also, the complication of the physical processes and socio-economic issues in this area is great challenge for practitioners and communities to have full understand flood pattern and associated risk. Therefore, this study selected Vu Gia . Thu Bon river basin, one of the largest system in Vietnam, to apply an integrated approach, including 1D flood simulation (using MIKE NAM and MIKE-11), Arc-GIS based mapping and conceptual DPSIR (Driver-Pressure-State-Impact-Response) framework to develop inundation maps of 10%, 5% and 1% frequencies and potential impacts in the study area. These results are considered as primary information to tailor effective flood disaster management plan in the long run.
