Abstract
After clarifying high-speed flow, pressure change, and scouring using model experiments when tsunamis overflow coastal dikes, the damage to coastal dikes caused during the Great East Japan Earthquake is summarized and the mechanism of categorized damage patterns of coastal dikes is discussed. Multiple logistic regression analysis is performed using external force acting affecting damaged coastal dikes and structure specifications, and overflow depth and armor width of landward toes are extracted as elements influencing such damage. Based on these results, structure innovation that persistently exerts effects during tsunami overflow is clarified for coastal dikes.
