Nonlinear wave interaction with a uniform current is described using numerical model, named CADMAS-SURF This model is based on the Navier-Stokes equations coupled with Volume of Fluid for tracking free surface deformation and developed for interaction of wave with structure. The CADMAS-SURF is extended to simulate nonlinear fluid dynamic motions on the wave-current coexisting field. The capability of Numerical Wave-Current Tank (NWCT) is validated by comparing with available experimental data for both wave-following and wave-opposing current. The numerical results are shown to be in good agreement with experimental data. In addition, this study investigated on the dynamic motions of the water velocity, surface elevation and vorticity within combined wave-current field in demonstrating complex nonlinear physical phenomena due to interaction. Furthermore, NWCT is applied to simulate a more complex wave-current-structure field for wave propagating over a submerged breakwater associated with current.
