In this study, the effects of computing time and particle spacing on water surface fluctuations were investigated by coupling between DualSPHysics and SWASH model. As a result, it is found that the coupling model reduces the computing time even for a vertical 2D model. It was also found that the water level rise was different from the actual water level movement when the particle spacing was large. It is necessary to set an appropriate particle spacing for the target wave height.
