Analysis of rubble mound foundation failure of a caisson breakwater subjected to tsunami attack

Abstract

Presently, there is no methodology to evaluate the deformation that the rubble mound of a caisson breakwater would suffer if it was attacked by a tsunami. The present paper proposes a methodology to evaluate this deformation based on the method of Esteban and Shibayama (2006), which originally was developed for wind waves. The method was verified by carrying out laboratory experiments using solitary waves and comparing the results to those obtained using the new methodology.
