영문 초록

  Copeland"s(1985) hyperbolic mild-slope equation including diffraction, refraction and reflection in the wave field is used as a governing equation in this study. Maruyama & Kajima"s(1985) result is used to calculate wave direction and Watanabe & Maruyama"s(1986) is used as a energy dissipation formula. Numerical solutions are obtained by Leap-Frog scheme and compared with Watanabe & Maruyama"s(1984) hydraulic experimental results and numerical simulation results for the detached breakwater. This wave model is applied to a detached breakwater and compared with Watanabe and Maruyama"s(1984) hydraulic model results to check the characteristics of reflected wave field around a detached breakwater. The distribution of wave height and wave phase in front of a detached breakwater is more accurate than the Watanabe and Maruyama"s numerical results. The results from our wave model show good agreements with the others and also show nonlinear effects around the detached breakwater. This model is applied to the Gamcheon harbor of Pusan region. The field observations were carried out at Pusan harbor wave station on 1986-1995 and the results were accepted as a design wave condition in this study. The wave height and wave period was measured by Dong-A university at one station in the Gamcheon harbor on 1996-1997 and used as a calibration criterion. The measured data were used as input data for numerical simulation and also compared with simulated results. The numerical simulation shows a farely good results which considering the effect of topographic characteristics and effect of narrow entrance due to two separated breakwaters in Gamcheon harbor. The wave distribution characteristics in the inside Gamcheon habor is farely different with the offshore wave direction and wave period.
