It originates in generating of the serious tsunami damage which is caused by the Tohoku-Pacific Ocean Earthquake. Need for the research and examination about several tsunami dameges is increasing.
Although there are many researches about stability of wave absorbing blocks which are causing little action of them under wave conditions, there is few researchs about the great migration of the block groups and the usability of wave absorbing blocks after great migrations under tsunami condition.
In this study, hydraulic model experiments remaking the groups of wave dissipation blocks which are set in front of the revetments facing the outer sea have been done. This paper aims to acquire the fundamental knowledge on the forms and mechanisms of extensive sufferings of the blocks due to the over-designed tsunami forces and influence on the vicinity.
