Abstract 

    To maintain the calmness of the harbor, rubble mound breakwaters are one of the practical measures to protect sailing and mooring waters. This paper investigates the effect of relocated rubble mound breakwaters on tranquillity in Busan yacht range and the impact of bridge piers at the entrance of the yacht range based on physical hydraulic modeling using multi-directional random waves. It is obtained that the sufficient tranquillity can be due to securely moored yachts, owing to newly relocated rubble mound breakwaters away from piers. The experimental results also showed the distribution of the energy difference’ dependence on various wave directions. The experimental findings are valuable for the design of Busan yacht marina, and are of reference to other port projects.
