Using numerical models to test the effectiveness of accretion in Soc Trang and Ca Mau provinces

Abstract

The application of numerical models to simulate nearshore wave propagation process, wave interaction, flow and sediment transport is very popular nowadays. This paper proposed combining the two numerical models Swash and XBeach to calculate the efficiency of accretion for two sub-regions belonging to Soc Trang and Ca Mau. The calculation procedure began with the Swash model to calculate the wave transmission, and then the XBeach model was used to calculate sediment transport and sedimentation. The results showed that the average accretion rate was 30-35 cm/year, which is relatively accurate in the range of 30 m behind the bamboo fences.
