Abstract

An approach using the nonlinear wave model in predicting wave-induced currents is presented. The model results were compared with those of the conventional model using phase-averaged radiation stress, and in addition with experimental data captured by a PIV system. As a result of comparison of wave-induced currents generated behind the surface-piercing breakwater and submerged breakwater, eddy patterns appeared to be similar each other but in general numerical solutions of both models were underestimated.

비선형 파랑 모형을 이용하여 해안류를 산정하는 모형이 소개되었다. 기존의 잉여응력을 이용한 수치모형 결과와 비교하였으며, 두 수치모형의 타당성 검토를 위하여 PIV 시스템으로 획득한 실험자료와도 비교하였다. 방파제 및 잠제 후면에서 형성되는 해안류에 대하여 서로 비교한 결과, 소용돌이 흐름의 형태는 유사하나 관측 결과와 비교하여 수치 모형 결과가 대체로 과소평가되고 있다.
