투과 사석방파제 주변의 파랑장 해석

Abstract

In this study, a method that leads to make a simple decision on important parameters in analysis ofwave field in permeable rubble-mound, block-mound breakwater, such as penetration velocity of incident wavesand resistance coefficient, is introduced. A model that could analyze wave field of permeable breakwater inharbor, by aplying these methods and arbitrary transmision coefficient boundary condition to a time-dependentmild-slope equation, was introduced. The verification of the model was done by carying out 2-D physical modeltest on permeable breakwater, measuring the change in water surface elevation, comparing the computationresult 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 aharbor.
