Wave Height Reduction Inside Pohang New Port, Korea, Due to the Construction of a Detached Breakwater

The effect of a detached breakwater, which was constructed to improve harbor tranquility inside Pohang New Port, examined through the comparison wave data measured before and after construction breakwater. observation showed that energy effectively reduced by although height outside breakwater higher its construction. in all wave-propagating directions, but it also observed became less effective protecting against northeastwaves than NNE waves. BOUSS-2D Boussinesq-type model employed analyze pattern propagation, showing that, breakwater’s construction, NE waves could directly enter port, increasing port. After simulations blocked approaching port from both heights extreme direction increased. Considering estimated probability failing preserve only 0.2–0.5% for these waves, concluded no secondary structures were necessary, existing sufficient protection
