Abstract

Tsunami attenuation ability of coastal forests is attributed to the fluid resistance of their elements; such as a trunk, branches and leaves. In order to evaluate the fluid resistance precisely, quantitative relationships among these elements and the characteristics of their forms should be clarified. This study applies findings in the tree morphology to the modeling for coastal forests. The tree crown region is herein modeled as a three dimensional porous structure. Based on the mathematical model developed here, effects of wave and forest properties on the tsunami attenuation rates are discussed.
