Abstract

A 3D numerical model for the sea bed response under free surface water waves is constructed. Free surface is modeled by Volume of Fluid (VOF) method and water wave is generated by numerical wave maker boundary condition. An iterative numerical scheme is proposed to solve Biot consolidation equation using finite volume method (FVM). The coupling between water wave and sea bed is through pressure and stress condition on common boundaries. Numerical test shows good agreement with analytical solution. 3D application of sea bed response under waves with the presence of object is also carried out to investigate the liquefaction potential.
