Impact of Flood Risks on Service Disruptions of Critical Infrastructures by the Example of the Euskirchen County, Germany

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT The increasing severity of flood events poses growing risks to critical infrastructures (CI), with failures often triggering cascading effects across sectors. Despite this, flood risk management (FRM) frequently overlooks service disruptions of CI and systemic interdependencies between infrastructure sectors because of its place‐based approach.
