PERFORMANCE OF A DOUBLE-WALLED BREAKWATER WITH AN INCLINED PLATE ARRAY AS A FRONT WALL

In order to reduce secondary effects caused by high reflection waves from conventional curtain-walled breakwaters, a double-walled breakwater consisting of a permeable and impermeable walls was newly proposed. Inclined plate array with the same draft as a rear wall was used as the front wall. Effect of the inclination angle of the plate array on the wave transmission and reflection coefficients as well as energy dissipation ratios was extensively examined. It was confirmed that the front wall comprised of the plate array with downward inclination angle is more effective than the one with upward inclination angle.
