Flood-adaptive green infrastructure planning for urban resilience

Abstract

Urban flooding in South Korea continues to affect the lives of people. In this study, we propose flood-adaptive green infrastructure planning to enhance urban flood resilience. Specifically, a strategy for responding to flooding was established based upon the "4Rs" in the concept of resilience: robustness, rapidity, redundancy, and resourcefulness. The effects of reduced stormwater runoff were then simulated for Gangnam-gu, Seoul, via the application of green infrastructure. Finally, a design matrix was established based on the flood-adaptive design strategy and simulation results. By presenting a resilience- and green infrastructure-based planning strategy, this study may be useful for urban flood resilience measurement and adaptation as well as sustainable urban design and planning.
