| Outline of Final Research Achievements |
The Great East Japan Tsunami destroyed the coastal embankments because of local scouring behind embankment induced by tsunami overflow. For tsunami mitigation, suitable arrangement of multiple tsunami measure structures is very important. The objective of this study is to estimate effect of a combined position of coastal forest and embankment on tsunami flow pattern, fluid force acting on tree and scouring behind coastal embankment by the hydraulic model experiments. Moreover, tsunami mitigation effect by local scouring is estimated by the numerical simulations.
