Abstract:Fifteen formulae of wave transmission coefficient for submerged breakwaters obtained during last 3 decades are presented, compared, and analyzed in this paper. The dimensionless parameters mainly involved in this discussion are the relative submerged depth R_c/h, relative wave height R_c/H_I, relative rubble size B/D_(50), relative breakwater width B/(H_I L_0~(1/2)) and wave breaker index ξ. It indicates that there exist notable differences among the computed results, which mainly originate from the limited experimental conditions and different analytical methods, even though the major tendency keeps similar. It is necessary to conduct more systematic studies to obtain better understanding about the mechanism of wave transmission over submerged breakwaters.
Keywords:submerged breakwaters  wave transmission formulae  discussion
