Abstract

This study addresses the challenge of modeling flood propagation and cascading failures in geographically interdependent transportation and stormwater systems, filling a critical gap in the literature by effectively capturing the temporal progression and spatial distribution of failures in interdependent systems. We developed a contagion-based Susceptible-Exposed-Flooded-Recovered (SEFR) model to monitor flood propagation dynamics within these interconnected systems. We established a spatial interdependency threshold for transportation and stormwater systems using a multilayer network representation and incorporated the state-of-the-art Hydrologic Engineering Center's River Analysis System (HEC-RAS) to generate reliable flood data. The SEFR model combines the topological characteristics of the multilayer network with simulated flood data to accurately model the propagation of flood damage and cascading failures. Focusing on Norman, Oklahoma, we calibrated the SEFR model using the HEC-RAS 2D flood simulation data for a major precipitation event on July 27, 2021. Results demonstrate the SEFR model's ability to identify the spatiotemporal variations in flood propagation, highlighting critical infrastructure components at risk, including specific road segments and stormwater system elements vulnerable to cascading failures during flooding events. The findings provide new insights into interdependent system resilience and inform intervention strategies to mitigate adverse flooding impacts, enhancing the robustness of critical infrastructure against natural disasters.

期刊介绍: The International Journal of Critical Infrastructure Protection (IJCIP) was launched in 2008, with the primary aim of publishing scholarly papers of the highest quality in all areas of critical infrastructure protection. Of particular interest are articles that weave science, technology, law and policy to craft sophisticated yet practical solutions for securing assets in the various critical infrastructure sectors. These critical infrastructure sectors include: information technology, telecommunications, energy, banking and finance, transportation systems, chemicals, critical manufacturing, agriculture and food, defense industrial base, public health and health care, national monuments and icons, drinking water and water treatment systems, commercial facilities, dams, emergency services, nuclear reactors, materials and waste, postal and shipping, and government facilities. Protecting and ensuring the continuity of operation of critical infrastructure assets are vital to national security, public health and safety, economic vitality, and societal wellbeing. The scope of the journal includes, but is not limited to: 1. Analysis of security challenges that are unique or common to the various infrastructure sectors. 2. Identification of core security principles and techniques that can be applied to critical infrastructure protection. 3. Elucidation of the dependencies and interdependencies existing between infrastructure sectors and techniques for mitigating the devastating effects of cascading failures. 4. Creation of sophisticated, yet practical, solutions, for critical infrastructure protection that involve mathematical, scientific and engineering techniques, economic and social science methods, and/or legal and public policy constructs.
