Outline of Final Research Achievements |
For greater efficiency, disaster prevention forests should maintain high resistance against fluid force caused by phenomena such as tsunamis and strong winds. In this study, the relation between fluid force and the resistance of trees against it was investigated and the effective structure of a disaster prevention forest was revealed. The result indicated that it is important to decrease the stand density to improve the resistance against fluid force, but it suggested that the resistance did not improve against tsunamis even if the stand density was low when the inundation was higher than the tree height.
