Harbor tranquality plays an important role in the appropriate disposition of harbor structures. However, it is not easy to get the accurate computational results because they are affected by many factors concerning with the wave transformation.
Recently, numerical model which are more economic and rapid than hydraulic model experiments are carried out for the purpose of analyzing wave height distribution.
Wave height distribution in the study area was numerically simulated for the optimum design. A deep-water design wave is estimated based on stochastic extreme wave analysis of wind data (Meteorological Administration, GeoJe), and it is applied to the boundary condition. Mild slope equation that includes effects of frequency dispersion and non-linearity is employed for the simulation. The porosity and sponge layer are adapted to depict partial reflection and complete absorption of waves.
The purpose of this study was to assess the degree of harbor tranquality in the Jang spit port and the design wave was determined using the wave action-balance equation and the mild slope equation. To evaluate the degree of harbor tranquality for each plan(PL 00,PL 01,PL 02,and PL 03),modeled wave height distribution.
