Abstract
This study have examined port expansions plan for fishery port in the east coast of Korea, accordance with permission conditions for coastal port such as limit for the cargo volume and passenger demands on coastal tourism belt formation. The site have been chosen as a municipal coastal port by attracting the new ocean industry and building waterfront zone to leap as a hub of new marine tourism.

The five major alternative plans are being discussed, which is expansion of present fishery port on east side, different shaped of breakwater with dredging and reclamation for formation of a new south port, and massive construction on eastern and southern part for the future port expansion. Additionally the characteristics of the target port have affected by the fishery port function, consideration on an artificial island(M-land) project which is a recent successful foreign fishery port had been applied to plan F-land in this study.

Both numerical and hydraulic experiment could be considered for harbor tranquility analysis on proposed expansion plan. However, due to experiment limitations, numerical simulation approach was adopted for various expansion alternatives. Five 50years return period of deepwater design waves were sampled and analyzed to use as input on the wave action balance equation model SWAN and the irregular wave model Bouss-2D based on the strong nonlinear Boussinesq equation.

Allowable mooring wave height and harbor tranquility were figured out with both nesting method and reproduction of the strong nonlinear irregular wave properties, and analyzed differently with each proposed expansion plan. Results have shown generally high responses from Bouss-2D model and this was due to more precise reproduction of waves under shoaling effect, diffraction, reflection and other factors than wave action balance equation model. Therefore, Bouss-2D model should be used for harbor tranquility analyzation.

The numerical experimental results showed the most suitable plan was ALT-1, with satisfied harbor tranquility and reasonable economical sense. The extension of east breakwater and enlarged turning basin of F-Land plan have brought generally more stable harbor tranquility than ALT-1. F-land plan is more attractive because of parking space for visitors and fish storage space for fishermen. Also those results of other proposed plans hopefully could be used for basic data for future harbor expansion.
