This project aims to develop and implement an Extreme Weather Events Assessment Framework for evaluating the vulnerability of environmental restoration sites to natural hazard-related challenges. This framework seeks to assess and mitigate the impacts of extreme weather events, such as surface flooding, erosion, rising groundwater tables, and transport of chemicals of concern on remediation and constituent chemical efforts. By providing advanced tools for both immediate and long-term assessments, the project seeks to enhance the resilience and protectiveness of sites in the face of extreme hydrodynamic variability.

The technology consists of a dual-framework approach, combining short-term and long-term assessment methodologies. The short-term framework will utilize existing site data and computer models to provide forward-looking resilience assessments by evaluating possible impacts, identifying exposure pathways that may emerge from these impacts, and explicitly describing vulnerabilities and preventive measures associated with new exposure pathways. The long-term framework will focus on systematic data collection and validation to refine vulnerability assessments over time. This innovative approach will integrate advanced predictive modeling of surface water, groundwater, erosion, geochemical processes, and extreme weather impacts. Unlike current methods, the present framework incorporates dynamic data integration with real-time monitoring and predictive analytics, specifically targeting high-impact extreme weather events. The project will demonstrate the application of both frameworks at two Department of War (DoW) installations, with success determined by improved predictive accuracy, enhanced decision-making capabilities, positive return on investment, and stakeholder acceptance.

The Extreme Weather Events Assessment Framework will provide significant cost and performance benefits to the DoW compared to current practices. By enabling proactive identification and mitigation of natural hazard-related vulnerabilities, the framework is expected to result in substantial long-term cost savings through the prevention of weather-related damage and the optimization of resource allocation. Performance benefits include more accurate and dynamic vulnerability assessments than traditional periodic evaluations and implementation of timely and targeted interventions. The framework's dual approach is agile and offers immediate actionable insights while continuously refining assessments. This enhanced capability is expected to improve the DoW's ability to maintain environmental compliance, protect communities and the environment, and ensure the long-term effectiveness of restoration efforts in the face of extreme weather-related hazards.
