Planning for just and sustainable urban regions, Paris, 8-12th July 2024In response to the impacts of climate change, the increasing risk of flooding has traditionally been addressed by identifying flood-prone areas using floodplain maps to regulate land development. However, the interconnected dynamics of runoff in the river basin and levee effect have highlighted the potential threats posed by residual flood risk. Consequently, this paper integrates residual risks and flood source areas into flood risk management within the river basin. Utilising the SOBEK model, this study simulates three flood scenarios—without levees, with existing levees, and with failed levees—to conduct flood hazard analysis and flood source-to-impact analysis. Based on these findings, this paper proposes land use management strategies aimed at enhancing water resilience through strategic spatial planning in the face of climate change.
