WAVE ABSORPTION AND WAVE FORCES ON A LOW-CRESTED DETACHED BREAKWATER COMPOSED OF SLIT WALLS AND FILLING

Abstract

 Characteristics of wave absorption and wave forces on a low-crested detached breakwater composed of slit walls and filling was studied by CADMAS-SURF. Four types of the breakwaters which have various slit walls were calculated. In the results, the largest wave energy loss was got by a type of all slit walls (three vertical walls and two horizontal walls). Wave forces on this structure were reduced and the reduction factors for horizontal and vertical wave forces were treated as modified Goda's formula. Moreover, designed cross section was practical for required safety factors of sliding and overturning.
