ABSTRACT: The The evaluation of the wave-induced liquefaction potential is an important issue that must be considered in the design of foundation around coastal structures. Most previous studies have been limited to either two-dimensional cases or non-breaking waves. In this paper, an integrated model for the wave-induced seabed response in a porous seabed is estab-lished. In the model, both non-breaking and breaking conditions are considered. With the numerical model, the wave-induced liquefaction potential in Gold Coast region is calculated. Numerical results demonstrate the significant differences between non-breaking and breaking waves-induced liquefaction potential.
