This $449,973 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund research at Virginia Polytechnic Institute and State University from March 1, 2023 to February 28, 2026. The university will study the physical processes controlling the amount of fine sediment in streambeds. Researchers will analyze EPA data to predict fine sediment accumulation across stream networks from flow conditions. They will also measure temporal variability in fine sediment through field measurements and quantify relationships between flow conditions and accumulation under different sediment scenarios through laboratory experiments. Broader impacts include engaging the public at Virginia Tech's Science Festival and with local fifth graders to discuss stream habitats and increasing awareness of diverse scientists. The goal is to improve understanding and management of aquatic ecosystems and basin-scale geomorphology.
