Abstract: Shoreline change rate has been used to discuss the distribution of sand input from the Thu Bon River in Central Vietnam. According to the rate of shoreline change, longshore sediment transport rate (LSTR) along the coasts of Thu Bon River delta were evaluated. In addition, the asymmetric distribution of sediment input from the river at the Cua Dai River mouth (Thu Bon River mouth), Vietnam was revealed. In which, nearly 85% of sediment supply from the Thu Bon River is being distributed to the right coastline. Transport of sediment to the north by wave-driven longshore currents together with asymmetric distribution of sand supplied from Thu Bon River is causing severe erosion on the left beach of the Cua Dai River mouth
