Coastal storms generate compound hazards that simultaneously impact transportation, power systems,
buildings, and coastal protection infrastructure. DM2L develops integrated frameworks that connect
coastal hazard simulation with lifeline disruption and recovery trajectories
to support planning, mitigation, and investment decisions.

Core Research Focus

• Coupled coastal hazard exposure (wind–wave–surge–flood)
• Transportation accessibility and service disruption modeling
• Lifeline performance metrics linking damage to functionality
• Scenario-based recovery trajectory simulation
• Decision support for mitigation, prioritization, and resilience investment

What Has Been Done

• Developed physics-based vulnerability models for coastal infrastructure and communities
• Quantified compound hazard effects on infrastructure performance and disruption risk
• Advanced approaches that translate hazards into actionable system-level metrics

What We Are Doing Now

• Integrating coastal hazard fields with transportation and power network models
• Quantifying accessibility loss and critical-path disruption under multi-hazard scenarios
• Developing scalable tools for lifeline digital twins and resilience dashboards

Strategic Plan

1. Develop coastal lifeline digital twin workflows for disruption and recovery analysis
2. Enable probabilistic disruption mapping and scenario planning for agencies
3. Couple lifeline performance with interdependency and cascading risk models
4. Support mitigation strategy evaluation and long-term adaptation planning

How This Connects

This thrust bridges multi-hazard mechanics and lifeline resilience, providing inputs to
interdependency/cascading modeling and community resilience decision frameworks.
