| Outline of Final Research Achievements |
Since 1950s, the large number of flood control facilities such as dam, levee, and flood storage basin has been constructed in Japan. These infrastructures reduced the frequency of flood, and it made population and property accumulate in the flood area. Since such area is still vulnerable for flood, the potential of economic loss may increase. Then, it is assumed that socioeconomic risk structure changes to low-frequency and catastrophe type. This is a paradox of flood control. In this paper, spatial land use patterns are observed before/after construction of flood control facilities, and the dynamic changes of flood risk curves are empirically analyzed to confirm this paradox. Then, the need for integrated flood risk management is proposed and the effectiveness of land use regulation for flood area is tested.
