Many researches of the past about the analysis of large scale's deformation induced wave force assumed that the ground is continuum. But the property of construction between assumed ground and actual ground is significantly different. Recently, analyses about seabed deformation are accomplished using Distinct Element Method (DEM) for that problem. But these researches were simplified by to construct the ground with elements of one scale, to use few particles, to apply simplified cyclic water-pressure etc. for the stable computation. Therefore the results of analysis are difference as compared with the actual states. In this study, we tried to analyze about seabed deformation using the seabed which it is constructed by variable particles by DEM with VOF. As a result, although this study has some problems awaiting solution, the present model was able to reproduce of seabed deformation due to wave action.
