Climate Impacts, Adaptations, and Resilience

This research examines rapid changes in climate and land use and their influences on flood hazards and associated risks with the goal of developing policy-relevant frameworks for building community resilience. The work focuses on developing risk-based approaches to assess both conventional and innovative mitigation strategies within changing anthropogenic conditions. It also informs watershed-scale flood risk management policies by analyzing the socio-economic benefits and environmental impacts of different adaptation approaches, as well as identifies land use or flood mitigation decisions that may be maladaptive over the long-term. As aging U.S. infrastructure faces increasing climate pressures, this work provides critical insights for resilient flood risk management strategies that can adapt to evolving conditions and support sustainable community development over decadal timescales. 

Financial Risk &
Climate Vulnerability

 

We examine how long-term flood exposure threatens the financial vulnerability of households under a changing climate.​

Land Use &
Policy Adaptation

We evaluates how local land use decisions, floodplain policies, and development trends can unintentionally compound risk to support reduction in community vulnerability.

Watershed Resilience & Infrastructure Adaptation 

We model flood risk across changing urban landscapes and watersheds, supporting resilient infrastructure planning in the face of shifting floodplains and long-term climate pressures.
