Abstract: The rising sea water level due to climate change is a serious issue and has been interested, researched and proposed by the developed countries. In Vietnam, the evaluation of the impact of sea level rise due to climate change on a number of areas of economic and life has also been studied. However, to assess the impact of rising sea water level on port system in Vietnam has not been studied. In this article, the authors refer to the impact of rising sea water level on tide at the port areas in Vietnam. The authors also present a specific application for calculating tide in Da Nang port location with the sea level rise 0.5m and 1.0m. The method for calculating the wave tide in the sea port locations with the sea water level rise is used MIKE 21 software. For simulation, input data are bathymetry and tide for boundary conditions. Tidal data is measured on site. The authors present a specific application for calculating tide in Da Nang port location with the sea level rise 0.5m and 1.0m. Water level data used to verify the calculation results of the model are taken from measured data in Da Nang seaport locations with time from January 01,2012 to January 16,2012. Based on the comparison between measured water level data and model results, it can be seen that the similarity in amplitude and phase is very high. The results from model also show that when the sea water level rises of 0.5m, which lead to water sea level at Da Nang port position rise 0.4m. If the sea water level rises of 1.0m, water sea level at Da Nang port position adding 0.75m.
