WAVE PROPAGATION MODELING FOR PUSAN NEW HARBOR

Abstract

For the basic design of Pusan New Harbor that will be the third largest container hub-port in the world, extensive wave measurements and wave propagation modeling were made. They are mainly for estimating shallow-water design wave height and determining breakwater alignment to acquire harbor tranquility. The directionality of short crested waves is proved to be very important when they propagate through the waterway. Bounded long-period waves with a small amplification were observed in the shallow water area, which might cause horizontal motions of the container ship moored at a berth aligned to the south. Modified and extended numerical wave models are found to be reasonably good at simulating the measured wave propagation phenomena. Hybrid modeling was made to evaluate harbor tranquility combining numerical and physical modeling results.
