Title: Experimental Study on Stability of Armor Units of Rubble Mound Breakwater against Tsunamis

Water depth and velocity were measured on the rubble mound breakwater to discuss the applicability of an experimental formula. The water depth and velocity were also estimated applying 2D numerical simulation for complementing velocities which were not obtained by the experiments. Soliton fissions generated in short period tsunamis were also simulated. The present work has revealed that the mass of armor units is underestimated if the Isbash's formula is used for the rubble mound breakwater.Read More
