Progressive water waves can be severely damped over muddy beds. This damping is assigned to the bottom pressure of the wave deforming the viscous mud, creatinga wave on the interface between the water and the mud, defined as the lutocline. The movement of lutocline can cause mud migration through Stokes drift [1]. Forprediction of damping mechanism, several theoretical, experimental and numerical studies have been carried out. In this research, ALES-VOF method has beenimplemented in the WISE 2DV non-hydrostatic numerical model [2] for simulation of wave-mud interaction. For a more accurate simulation of water free surface andinterface of mud and water, advantages of ALES and VOF methods are integrated.
