Abstract: Sea level rise is causing a significant increase in the frequency and severity of coastal flooding, natural hazards for coastal populations, infrastructure, constructions or ecosystem. Climate change and weather anomalies are making the more rapid sea level changes. In Vietnam, meanwhile, development of coastal urban areas is a hot trend and of interest to investors. So, it is of necessary to identify the observed and future potential sea level changes. This paper analyses and represents the observed and projected sea level changes for Vietnam. More importantly, inundation mapping is implemented to fully interpret the potential effects of sea level change for urban areas of Vietnam. The data of 10 tide gauges in the whole country and satellite-based from 1986 to 2019 are used to analyse the observation sea level changes for coastal zones of Vietnam. The CMIP5 models are selected for projecting the sea level changes and GIS technology is applied to map for the coastal inundations. The results illustrate an increasing trend of observed sea level up to more than 10 mm per year. Regions affected by sea level rise are significantly large, especially in the Red River Delta to Danang province and Mekong Delta.
