| Outline of Final Research Achievements |
It aimed at the construction of the slope failure risk estimation method of the mountainous forested basin using the distributed runoff. The distributed runoff moderl has the two step tank model that can separete the overland flow.The model was applied to the Saba river and the Tomita river. The horizontal, perpendicular distribution of underground water, and the place and the form of the slope failure were quantitatively discussed. It was confirmed to be able to presume the small watershed where the slope failure was generated easily and the form of the slope failure by using this runoff model. Because the same deal had been obtained in all basins including Nakagawa that had been applied before this research, the generality of this method was shown.
