A novel two phase flow surf zone model, which may account for the effect of entrained air under breaking wave, has been developed. A variation of conservative Level Set Method is used to capture the airwater interface. This method allows the model to run stably up to hundreds of waves without significant mass loss. Air-water interface is well controlled and maintained even after long time integrations. Therefore, this model could be potentially used to simulate scour which occurs over many wave cycles. In this presentation, we will introduce the detailed algorithm and our tests on the spilling breaking wave simulation. Although the computational results are strongly influenced by the numerical schemes, we have identified a scheme that can fairly accurately predict the phase averaged surface elevation, location of breaking point and undertow.
