Previous studies have overlooked the impact of events beyond the design limits of CI, underscoring the need to identify operable infrastructure. The study examines the impact of CI, including electricity, water resources, and road systems, on flood resilience. It specifically distinguishes areas with mild flooding from those with severe flooding based on the Flood Resilience Index (FRI) impact. Focusing on a transitional area with diverse land uses, the study reveals that serious damage to CI during flooding events reduces FRI. Urban areas experience more significant impacts despite having a higher density of CI. Conversely, in rural regions, the FRI leans heavily on Exposure, whereas in urban settings, both Exposure and Sensitivity hold significant influence. The findings emphasize the role of CI in enhancing FRI and the necessity for timely interventions in fortifying resilience efforts.critical infrastructure (CI)disaster risk managementdynamic risk mapFlood Resilience Index (FRI)transitional area[SDGs]SDG9[SDGs]SDG11conference paper10.1201/9781003475378-142
