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.
