The National Science Foundation (NSF) has awarded a Project Grant under the Geosciences program (CFDA 47.050) to Virginia Polytechnic Institute & State University (Virginia Tech) for $439,620. The award, effective September 1, 2025, supports a collaborative research project titled "Flocculation Dynamics in Estuarine Boundary Layers - Advancing New Understanding through an Integrated Field, Laboratory, and Computational Study." The objective of this 3-year project is to advance the general understanding and predictive capability of coupled flocculation dynamics and sediment transport in estuarine and coastal zones. The research will integrate field observations, laboratory experiments, and computational modeling to address key knowledge gaps related to the control of floc size, settling velocity, and their relationship to bottom shear stress and sediment suspension/deposition. The project aims to inform the development of flocculation models that can be effectively coupled with existing open-source coastal models, with potential impacts on broader research communities in biogeochemistry, carbon cycling, ecosystems, and water quality.
