| Outline of Final Research Achievements |
To enable a large-scale river planning considered connections of whole river basin, we developed novel numerical and mathematical tools, and checked their validity by applying them to flood events with different temporal and spatial scales. The tools are composed of flood physics model, flood economic model and flood evacuation model. The flood physics model is the most fundamental part for the river planning, and is divided into 4 components, the large-scale inundation model, inner-outer inundation connected model, flood induced local flow model and tsunami model. Those tools were tested through the applications to past flood events with different scales, and the results were compared with observations. Such calibration process showed that the river planning aided by the proposed new tools are quite useful and practical. Some components of the results were assembled as free-software on an open-source platform to enable everyone in the world can use our result without limitations.
