Assessing the economic impacts of compound risk at Glynn County

Coastal Georgia is vulnerable to compound risks from coastal inundation and environmental contamination by hazardous materials. These risks are not borne evenly by its population but instead disproportionately threaten underserved communities. Using Glynn County, GA, as a case study, this project proposes to quantify the compound risks of coastal inundation and contamination, and to estimate…

Towards an Operational Compound Flood Model for the St. Johns River 

UGA has partnered with the NOAA Southeast River Forecast Center and its chief hydrologist, John Schmidt, to develop a real-time compound flood forecast model for the St. John River watershed in Florida. The project will involve developing state-of-the-art numerical models that could simulate coastal and hydrologic processes in real time. This model is urgently needed…

EPA Region 4 Environmental Justice Thriving Communities Technical Assistance Center

The EPA Region 4 Environmental Justice  (EJ) Thriving Communities Technical Assistance Center (TCTAC), housed at RTI International, serves all the states within the EPA Region 4 (Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, and Tennessee). UGA is the lead institution in Georgia, and our team includes community-based organizations such as ECO-action and VCI (Vulnerable…

Integrating Coastal and Riverine Natural Infrastructure to Reduce Multi-Flood Hazards

As the world moves towards resilient and safe solutions against natural disasters and climate change, numerical modeling of Natural and Nature-based Features (NNBF) has been a beneficial approach in recent years. However, when it comes to estuarine regions, it is vital to analyze these features as a holistic system to understand and even predict their…

About the CITRA Lab

The Compound Inundation Team for Resilient Applications (CITRA) research group bridges the gap between academic research and practical application. Our team uses the latest technology to solve complex water resources problems covering inland and underground regions to coastal and estuarine locations. An essential component of any project is the dissemination of the results, thus CITRA engages the community and stakeholders by simplifying complex concepts into simple analogies.
