浅野俊之、藤宫佑介、伊藤丹等人认为沿海森林的海啸衰减能力是由其元素的流体阻力决定的；如树干、树枝和树叶。为了准确地评价流体阻力，必须明确这些因素之间的定量关系及其形式特征。本研究将树木形态学的发现应用于沿海森林的建模。本文将树冠区域建模为三维多孔结构。在此基础上，讨论了波浪和森林特性对海啸衰减率的影响。
Toshiyuki ASANO, Yusuke FUJIMIYA and Dan ITOH 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.
