Development of New Seawalls of Low Crest Types

Abstract

Classified three types of seawalls, which are effective to decrease wave over-topping even with their lower crown heights, are newly developed. One type is with steps on the front face, second one is with a chamber behind slits on the front face and third one is with wide plane area between front and rear steps. The effect of these on the decrease of wave over-topping is verified by experiments.
