An Experimental Study on Wave Forces of Composite Breakwater with Discontinuous Wave Dissipating Blocks

Goda's formula is standard expression for the wave forces of composite breakwater, but it underestimates on condition of the impact breaking waves. On the otherhand, Takahashi et al (1992) introduced the coefficient of impact breaking wave forces (ai) into Goda's formula. In this paper, we study on the characteristics of wave forces on the breakwater discontinuous wave dissipating blocks. On that condition we confirm that impact breaking wave forces work on, and show the introduction of ai with regard to estimation of wave forces.
