Abstract

Rikuzentakata City suffered great loss due to the tsunami caused by the Great East Japan Earthquake and it was found that many video or photo materials could be used for the observation of tsunami process in this area. Therefore, both the video analysis and the numerical analysis based on the non-linear long wave theory were conducted to describe and simulate the tsunami process. Besides, in the numerical analysis, the height of coastal dike model was set as the parameter to study the prevention effect of coastal dike on tsunami process. As a result, the outflow mechanism of Kesen Bridge in Rikuzentakata City was explained and the prevention effect of coastal dike on tsunami process was investigated.
