| Outline of Final Research Achievements |
A heavy rainfall on September 11, 2015 resulted in flooding and landslides in Miyagi Prefecture of Tohoku Region, Japan. Especially, flood inundation damages caused in the Shibui River, one of the tributary of Naruse River, was severe. In this study a rainfall runoff and flood inundation model was applied to the Shibui River in order to reproduce the flood situation in the river. In addition, probable maximum flood and hydrodynamic force of flood inundation were evaluated based on numerical experiments under the several scenarios.
Numerical simulation results showed that the probable maximum hydrodynamic forces of flood inundation at the target area were not so larger as to result in sever damages of around houses under the considered conditions in the study. However, maximum inundation depths larger than 2.4 m were computed in some areas, and those areas are need to be considered as high risk zones.
