Abstract: Vietnam is located in the region of the Southeast Asia monsoon. Most of the population work in agriculture and inhabitants essentially concentrate at the coastal plain, Vietnam is one of the countries most heavily affected by the consequences of climate change. For these reasons, predicting the potential damages due to extreme flood events, especially under climate change impact is mighty necessary for the coastal area in this country. This paper will present the potential risk maps in Vu Gia Thu Bon catchment, a largest river system in Viet Nam central. These flood risk maps are built with tree GCMs under A2 scenario in the end of 21st century by overlapping the flood hazard and land use map in 30m resolution. The result is hoped to provide adequate scientific evidences to help local authority make suitable strategies for adapting with the variation of climate in the future.
