When it is difficult to raise seawalls due to a building height restriction such as for airport facilities, wave-dissipating works with a notch are adopted between the wave-dissipating works and seawalls. Although studies on wave overtopping of wave-dissipating works with a large retarding pool have been carried out, there are few studies of stability and overtopping of wave-dissipating works with a notch at the rear end of the crown. Then, the hydraulic model experiments were conducted to clarify the stability and overtopping characteristics. It was clarified that the blocks at the shoulder area of the crown rear were susceptible to damage due to the effect of the water mass that had passed over the wave dissipating works from the experimental results and that the amount of overtopping with there was a notch increased compared to without notch.
