A Boussinesq-type wave model is used to investigate the interaction of waves with a non-uniform current field. The numerical model is first tested for wave propagation in a wave flume of uniform depth without current. It is then tested in a wave flume for a submerged bar. The validated numerical model is of higher accuracy than the fully-nonlinear fourth-order model, which is one of the best forms among the existing conventional Boussinesq models that do not incorporate breaking mechanism in one dimension. Comparison of model results with laboratory data shows the model is capable of representing wave-current interactions. The effect of current on wave is studied for different incident wave conditions, and the wave blocking is simulated successfully.
