INFLUENCE OF REFLECTED WAVES FROM HARBOR LAND BOUNDARIES ON WAVE LOADS ACTING ON A DETACHED BREAKWATER

Abstract

 In order to mitigate meandering damage of a detached breakwater in a harbor region, wave height distributions and resultant wave loads about an isolated and finite length breakwater located offshore side of a straight land boundary have been studied from the theoretical point of view. Especially influence of reflected waves from the straight land boundary on wave loads acting on the breakwater is extensively examined for various detached distances between the breakwater and land boundary. In the examinations, characteristics of wave heights and wave forces on both sides of the breakwater have been clarified to obtain the spatial distribution of resultant wave forces along the breakwater line.
