Abstract
Flood control administration is facing the turning point of policy. The new directions are the following: 1)a shift towards policies that "reduce dependency on dams," 2)addressing issues associated with climate change, including excess flooding from localized torrential downpours, 3)proper maintenance, intensive use and improvement of existing infrastructure, 4)advanced flood control using advanced technologies from various fields, and 5)alteration of zoning toward creating a region that permits flooding in cooperation with the administration in charge of land use. In this study, I comprehensively analyze the history of flood control administration in Japan toward proposing permanent flood control measures, including those that provide for altering the land use of floodplains. The study aims to support the development of flood control principles for next-generation.
