Overview

Spatial risk assessment modeling reveals pronounced flood vulnerability along coasts and dense centers, highlighting critical lifeline infrastructure robustness for systemic disaster mitigation.

Key Points

To establish an integrated urban waterlogging risk assessment framework that captures systemic vulnerabilities by embedding critical lifeline systems into traditional hazard and exposure dimensions.
Integrated urban safety lifeline systems across hazard, exposure, and vulnerability dimensions to model systemic flood risks.
Combined the analytic hierarchy process (AHP), entropy weighting, and game theory to balance expert knowledge and objective data within a geographic information system (GIS) environment.
Applied the framework to municipal spatial data from Suqian City, China, alongside sensitivity analyses of infrastructure parameters.
Identified significant spatial heterogeneity in flood hazard, with the highest risk zones concentrated along lake coasts and in densely populated urban centers.
Sensitivity analysis revealed that the robustness of urban lifeline systems is a primary determinant in buffering systemic disaster propagation.
