In the hydraulic experiments, the characteristics of the flow through the gap were clarified using the steady flow. The results indicated that the apparent gap was different between cylinders and pipes and was in propotion to the water level difference. Next, the evaluation method by using the numerical simulations were verified to apply to the ports with complex shape using a real-scale virtual water channel. According to the results, the protection performance was affected by the size of the port and the height of waves and could be estimated by the rough estimation
