Coastal erosion is a natural phenomenon that occurs on the worldwide site of the coastal bank. The impact of natural forces such as wind and waves can change the formation of the shoreline and leads to coastal erosion. Eventually, this work is aimed to conduct a simulation of sediment erosion by using the Discrete Element Method-Discrete Particle Method (DEM-DPM). The simulation works reported that the number of particles changes as the time increase due to the generation of waves. Furthermore, the most critical division can be determined through this simulation as the number of particles starts to change from its initial state. It is also found that the lengthen of time would generally increase the number of particles erode and change the sand formation that will lead to erosion. In addition, the findings have been validated with the Smooth Particle Hydrodynamics method to investigate the effectiveness and accuracy of the numerical analysis of DEM-DPM. Based on the findings, Division A is the most critical division since the particle on that division is erode due to the behaviour of the waves.
