Climate change and sea level rise scenarios for Vietnam was published by the Ministry of Natural Resources and Environment in 2012. According to the scenarios, when sea level rise by 1m, over 20% of Ho Chi Minh City will become flood risk area affecting more than half million people (7% of the city’s population). This urgent problem affecting so many people like that but accessing to this information of the inhabitants is very limited. Therefore, the research Using the 3D technology to build flood model on WebGIS helps to show visually water level, flood position and the risk area affected in different water level. The research did not analyze the aspects of climate change, just used the results of the scenarios combining with 3D model technology on WebGIS to build an application. The result is not only the tool to help local people to access easily with the visual information about water level but also the reference for relating research and applications.
