This project will investigate the critical issue of saltwater intrusion in Delaware's complex coastal environment. Saltwater intrusion, the movement of seawater into freshwater resources, poses significant threats to the state's drinking water supplies, agriculture, natural ecosystems, and infrastructure. This project aims to advance understanding of the processes driving saltwater intrusion and develop strategies to mitigate its impacts. The research team, consisting of faculty, staff, and students from Delaware State University, Delaware Technical Community College, Goldey-Beacom College, Wilmington University, and University of Delaware, will collaborate with partners across the state to address this pressing challenge. They will collect field data, conduct experiments, and develop computer models to study how various factors affect saltwater intrusion in urban, suburban, rural, and natural areas. The project will also explore innovative solutions, such as developing salinity-resistant crops, facilitating marsh migration, and promoting wetland-based carbon removal. By engaging partners throughout the State and training the next generation of social and natural scientists and engineers, the project aims to enhance regional resilience and promote long-term economic well-being. Ultimately, the project will provide vital information to support sustainable water management, protect Delaware's valuable water resources, and ensure a resilient future for coastal communities in
