Harbor Tranquillity Analysis for Cheonha Harbor, Korea

摘要

Harbor tranquillity analysis is performed in order to suggest a counterplan to reduce the average wave height around the Quay-11 in Cheonha harbor, Korea, to less than 0.5m. For this analysis, a short period wave analysis program based on the Boussinesq equation is used. The shoaling, refraction, diffraction and partial reflection, of irregular finite-amplitude waves propagating over complex bathymetry are considered. From the results of numerical simulation, it is found that the effect of reclaimed land is almost not appeared. However, a new breakwater in front of the reclaimed land as the counterplan in this study makes the average wave heights on the sea area around the Quay-11 to be less than 0.45m. Therefore, it may guarantee the safety of vessels and improve the work efficiency.
