Structure of System-Specific Hazard Modeling for Physical Infrastructures in a Climate Change Context

arXiv:2607.26629v1 Announce Type: new Abstract: This paper addresses the definition and modeling of hazards in the context of physical systems, particularly infrastructures, that are affected by climate change. The paper highlights that hazards are system-dependent, meaning what constitutes a hazard for one system (e.g., humans) may not be the same for another (e.g., infrastructures). The paper also highlights that extreme intensity distribution may evolve in a region without necessarily constituting a hazard for a specific system. These distinctions are crucial for risk assessment and adaptation strategies in a changing climate. The paper implements a simple threshold-based hazard model -Boolean Hazard Model with Probability -to focus exclusively on system-specific hazard definition in climatechange context. Use cases illustrate how this approach adapts to different systems and hazard types. The model produces time-evolving hazard maps, delivering hazard data tailored to both hazard type and infrastructure characteristics. The model provides hazard data tailored to specific hazard types and physical systems, with a focus on infrastructure. The use cases demonstrate their practical value and potential for broader application in multi-infrastructure and multi-hazard exposure modeling.
