A STUDY ON THE EFFECTS OF URBANIZATION ON FLOOD INUNDATION IN THE KUROSE RIVER BASIN

In recent years, flood inundation due to urbanization and decreasing population have become problems. In response to these issues, it is necessary to consider land use from the perspective of flood control, and for this purpose, it is necessary to understand the impact of urbanization on flood inundation. In this study, two scenarios were developed for the Kurose River basin, and the effects of urbanization on flood inundation were assessed using DioVISTA/Flood. The results showed that urbanization increases flood inundation, especially in the upstream and downstream areas, and that some areas are prone to inundation due to topographical factors.
