This study deals with the influence of porosity and profile change of wave dissipating block layer on the wave overtopping and reflection by use of irregular waves. Two types of blocks with different porosity and the initial and deformed profile of block layer were used in the experiments and numerical computations. A model profile that consists of the depression of crest and the change of slope gradient was used as the deformed profile of the block layer. As a whole, the larger porosity of the block layer resulted in a smaller overtopping rate and reflection coefficient. Additionally, the overtopping rate increased and the reflection coefficient decreased by the deformed profile, then the difference of the overtopping rate by porosity of block layer became smaller than that in the initial profile.
