Abstract

In this study, a method that leads to make a simple decision on important parameters in analysis of wave field in permeable rubble-mound, block-mound breakwater, such as penetration velocity of incident waves and resistance coefficient, is introduced. A model that could analyze wave field of permeable breakwater in harbor, by applying these methods and arbitrary transmission coefficient boundary condition to a time-dependent mild-slope equation, was introduced. The verification of the model was done by carrying out 2-D physical model test on permeable breakwater, measuring the change in water surface elevation, comparing the computation result with time series, and comparing the result gained from the 3-D physical model test on permeable block-mound breakwater in an field harbor with the computation result in terms of regional wave height ratio in a harbor.

본 논문은 사석이나 소파블록 투과방파제로 이루어진 항만의 평면파랑장 해석모델에 있어서 중요한 변수인 구조물 내부의 투과파 속도와 저항계수를 수치모델에 사용하기 편리하도록 정의하고, 시간의존 완경사방정식 모델에 이들 방법과 임의투과율 경계조건을 사용하여 투과 사석방파제 주변의 평면파랑장을 해석할 수 있는 모델을 제시하였다. 모델의 검증은 조파수로 내에서 투과제에 대한 단면 수리모형실험을 실시하여 구조물 전$.$후 면의 수위변동을 측정하고 모델의 결과와 시계열로 비교하였으며, 현지 항만의 소파블록 투과제에 대한 3차원 수리모형실험 결과와 모델의 결과를 항내 구역파고비로 비교하여 이루어졌다. 본 모델은 검증을 통하여 수리모형의 실험결과에 대한 재현성이 매우 좋음을 확인할 수 있었다.
