Outline of Final Research Achievements

Unexplained mechanisms of interaction between fluids and solids often causes unpredictable and extensive damages into human lives as well as structures. In this study, focusing our attention to tide-protection forests against tsunami energies, we propose a method of multiscale numerical experiments for evaluating their disaster-reduction characteristics. For that purpose, we introduced a hierarchical way, a tide-protection forest is stratified into three spatial scales; branch-scale, tree-scale and forest-scale. A tide-protection forest is assumed to be porous media and we identify its porous term as reduction characteristics. Several cases of lower-scale analyses are carried out with different initial and boundary conditions to construct a response surface of the overall resistances at the upper-scale. Thus, with this information about the porous medium's characteristics, a whole costal region can be a analysis target to make a risk assessment for structures behind the forest.
