In this study, as a method of maintaining the performance of the wave-dissipating block sloping breakwater, the transmission coefficient with berm is examined by hydraulic model experiments and numerical calculations. As a result of the experiment, the transmission coefficient increases under the condition of the lower crest compared to the sloping breakwater of the basic shape, and it is improved by berm. By installing two layers of wave-dissipating blocks up to the still water surface, the transmission coefficient is equivalent to that of the basic sloping breakwater. As a result of the calculation, it is possible to reproduce the result of the experiment in general. When Rc/HI > 1, setting the characteristic value of the block further improves the accuracy with respect to the experimental results.
