Abstract

Travinh’s coastline is located in the lower Mekong River which is strongly influenced by changes in sediment load from the Mekong River and in sea level rise due to the effects of climate change. This study uses the Mike 21C F/M model to calculate the hydrodynamic regime and sediment transport in the Tra Vinh coastal zone with 5 scenarios (current status, sea level rise by 2030, 2050 and decrease of sediment discharge from the Mekong 20% ​​- 30%). This article presents the results of the calculations based on the relationship between variation in the depositional layer and time, the decrease of sediment load in the Mekong River and the sea level rise.
