A numerical model was proposed to analyse the combined effect of the pneumatic breakwater and the submerged breakwater for improving the wave damping performance, in which the Reynolds Averaged Navier-Stokes equations combined with the Shear Stress Transport (SST) k-ω turbulence model were adopted to investigate the flow field. A series of existing experiments were applied to validate the numerical model of the pneumatic breakwater and the submerged breakwater. The results indicated that the joint breakwater could dramatically enhance the wave dissipation capacity when the aerial barrier was located behind the submerged breakwater, and the transmission coefficient of the joint breakwater to the long waves could be decreased by 35% compared with the submerged breakwater working alone in some cases.
