| Research Abstract |
The trapping mechanism of floating objects during tsunami due to align trees was investigated through field survey and hydraulic experiments. From the field survey on The 2011 Tohoku-oki earthquake tsunami ; it was observed that when floating objects flow as a group, it is possible for them to be trapped even if their representative length is narrower than the interval length of trees, from the hydraulic experiments; it was possible to find the associated physical factors, and finally propose a simple formula to evaluate the trapping mechanism.
