Outline of Final Research Achievements

It is very difficult to cope with long term　changes in runoff characteristic, and also hard to estimate drainage ability which will change in various related conditions. A lack of knowledge about this type of flooding will delay the countermeasures used to address the disasters.A simple model to estimate this type of flood is proposed, which is composed of three steps. As a result, the difference is the roughly estimated drainage ability for the basin, which must be an important factor to address the flood disaster itself as a next step. Furthermore, the field observations on a series of flooding phenomena that occurred in June of 2016　were achieved. The inland flooding simulations based on the results of fieldwork have been created using a geographic information system.
