Short summary

A huge tsunami in Southeast Asia in 2004 has stimulated a debate about the role played by coastal ecosystems in protecting coastal area. Previous approaches assumed that vegetation is stationary and neglected the plant motion with wave. This may lead to overestimation of the effectiveness of coastal vegetation on tsunami damping. We present a coupled wave–vegetation simulation and conclude that the tsunami wave height damping may be overestimated if vegetation motion with wave is neglected.
