Abstract

From experiment data, the overtopping discharges were analyzed with 3 type of sea dike cross sections: (1) sloping dike, (2) sloping dike combined with vertical wall (3) sloping dike combined with perforated quarter circular breakwater on the top in case of the same crest elevation. The result shows that there is a equivalent of overtopping discharge between (1) and (2). Besides, the reflection coefficient of (3) (Kr =0.37-0.6), which is nearly same (2) (Kr=0.37-0.66) and better than (2) with Kr =0.52-0.71
