Abstract

The significance of coastal forests as a protection barrier against tsunami waves has been of particular interest following recent tsunami events. Coastal forests have been shown to attenuate tsunami-induced inundation and are believed to be capable of reducing the propagation of tsunami-borne debris onshore. The current paper aims to examine the suitability of using a Smoothed Particle Hydrodynamics (SPH) model to (1) simulate debris impact forces acting on a structure and (2) to determine if it is possible for a small coastal forest to attenuate tsunami-borne debris. The results of this study indicate that the SPH model utilized was able to reasonably replicate the hydrodynamic forces acting on structures and the water surface elevation, but was not able to reproduce the large debris impact forces observed in an experimental test program. However, the authors concluded that coastal forests can potentially provide protection against floating debris.
