Abstract: Coastal forest in the Tohoku and Kanto districts of Japan were destroyed by the Great East Japan tsunami on2011. However, coastal forest had some ability to reduce the damage by a tsunami even when they were broken. In this study, the effects of coastal forests on scouring behind coastal embankment induced by tsunami overflow have been investigated by the hydraulic model experiments with erodible-bed. The scouring length and souring width at landward toe of embankment becomes small with arrangement of coastal forest. Moreover, the energy reduction in erodible-bed with arrangement of coastal forest was larger than fixed-bed conditions.
