In order to create a safe and pleasant hydrophilic coast, the coastal maintenance projects are under way in the concept of the marine park. However, a lot of accidents are happened because of the unpredictable climate change and the accidents are increased due to the lack of safety in the Coastal Zone. The number of the accidents that the overtopping waves on the breakwater have swept the peoples on the breakwater into the sea result in the many deads, have grown in the recent. And the damage of facilities caused by overtopping wave have increased in addition to the casualties. In this study, the experiments of overtopping wave force acting on the handrail on the breakwater have conducted to consider the safety design for the handrail. Through the several types of the experiments, the dangerous wave patterns are identified, Also, the appropriate design guidelines and material for handrail to prevent the pullout of the anchor bolt are proposed.
