This study carried out experiments to investigate the behavior of overtopping flows in the vicinity of a caisson breakwater with dissipating blocks. Overtopping flows over a breakwater show horizontal momentum that causes significant damage to objects such as buildings, vehicles, or persons on the top. There is a need to understand overtopping flows on the top related to wave conditions to mitigate damage. This study measured front velocity and impinging distance of overtopping flows by monochromatic waves to examine flow behavior on the top and estimate overtopping flows over the rear slope of the breakwater model in varying wave conditions. Relationships among the parameters were also used to induce empirical equations through dimensionless analysis.
