Abstract
Samchunpo(Sin Hyang) Harbor is located in the bay of Sa Chun, the central south coast of Korean peninsula The harbor and coastal boundaries have been protecting by natural coastal islands and shoals. Currently, The Sin Hyang harbor needs maintenance and renovation of the sheltered structures against the weather deterioration and typhoon damages. Consequently to support this, the calculation of accurate design wave through the typhoon wave attack is necessary. In this study, calculation of incident wave condition is simulated using steady state spectrum energy wave model (wide area wave model) from 50 years return wave condition And this simulation results in wide offshore area were used for the input of the extended mild slope wave model at the narrow coastal area Finally, the calculation of design wave at Sin Hyang harbor entrance was induced by Boussinesq wave model (detail area wave model) simulation The numerical model system was able to simulate wave transformations from generation scale to shoreline or harbor impact. We hope these results will be helpful to the engineers doing placement, design, orientation, and evaluation of a wide range of potential solutions in this area.
Key Words: Steady state spectrum energy wave model;Extended mild slope wave model;Boussinesq equation;Design wave condition
