A finite element model has been developed to study the effect of currents on the wave propagation in and around arbitrarily shaped harbours of variable depth. The model solves an elliptic mild-slope type of equation for time-harmonic waves, and thus circumvents the limitations of existing models for wave-current interaction in coastal areas, which apply a parabolic approximation. Numerical examples are presented, both for schematized cases, as the effect of "rip currents" on normal incident waves on a sloping beach, and for a realistic geometry.
