dc.description.abstract파랑 잉여응력의 영향이 자동적으로 고려되므로 파랑으로부터 발생되는 흐름을 수치모의할 수 있는 수평 점성 및 난류항이 포함된 Boussinesq 방정식 모형인 FUNWAVE를 이용하여, 다방향 불규칙파 조건으로 해운대 해안에서 발생하는 이안류를 수치모의하였다. 수치모의는 다방향 불규칙파의 전파양상과 지형에 의한 비선형 파랑변형을 잘 보여주고 있으며, 이러한 파랑변형과 해운대 지형특성이 반영되어 시간에 따라 발달하는 파랑유도 연안흐름 양상을 잘 보여준다. 수치모의 결과로 부터 이안류는 연안방향으로 상대적으로 수심이 깊은 곳에서 그리고 파고가 낮은 곳에서 이안류가 돌발적으로 발생 혹은 증폭될 수 있음을 확인하였다.-
dc.description.abstractThe rip current occurred at Haeundae beach was numerically investigated under directional random wave environment. The numerical simulation was performed using a fully nonlinear Boussinesq equation model, FUNWAVE which is capable of simulating nearshore circulation since it includes the effect of wave-induced momentum flux and horizontal turbulent mixing. The results of numerical simulation show the time-dependent evolution of the wave-induced nearshore circulation system (including rip current) that are caused by nonlinear transformation of directional irregular waves due to unique topography of Haeundae. From the results, it was found that rip current is well generated and developed where relatively lower wave height and relatively deeper water depth along the longshore direction, and sudden and strong events of rip current were observed.-
