The erosion and deposition are occurring more complex and unpredictable in the long coastline country like Vietnam. This study using numerical model method to investigate the erosion and deposition possibilities in Binh Thuan coastal areas, an area located in south-central of Vietnam. By utilizing MIKE 21/3 Coupled Model FM, we compared the current situation with the simulation of erosion and accretion under two extreme conditional scenarios: wave with 1% frequency, and sea level rise (SLR). The study simulated the semidiurnal tide, a featured characteristic of Binh Thuan coastal areas during the southwest (SW) and northeast (NE) monsoon, results seafloor changes overs 15 days. The first scenario shows that in SW monsoon, the coastal sediment in the southern part of Binh Thuan is being carried away, and deposit in the northern coastline, especially at Phan southern coastline. The SLR scenario results erosion in both monsoons at the rate of 8 − 15 mm−1 day−1 , but with higher erosion rate in SW. However, there is an exception where the information, can be used for management to protect the human-induced activities as well as preparation adaptation plan for upcoming climate change not only in Binh Thuan province but also in entire Vietnam.
