Many breakwaters were damaged by the March 11, 2011 Tohoku Earthquake off the Pacific coast. The majority of the breakwaters were destroyed or deformed under tsunami overflow; however, the failure mechanism under tsunami overflow is not clear. It is supposed that caissons slid from the mound under tsunami overflow from video analysis of Kamaishi breakwaters, of which about half were damaged. Therefore, with the main objective of this report being to clarify the stability of breakwaters under tsunami overflow, hydraulic model experiments and numerical simulations were conducted with Kamaishi Bay breakwaters as the subject, and disaster mechanisms of the trunk of the breakwaters were examined.
