  3. New NSF project “Improved Observation, Analysis and Modeling of Fine Sediment Dynamics in Turbid, Biologically Active Coastal Environments” Understanding fine sediment transport is critical to managing coastal water quality and ecological health, and to understanding coastal ecology, chemical fluxes and the geological record. Bed erodibility and suspended particle settling velocity are the two largest unknowns limiting accurate prediction of sediment transport in muddy coastal environments. Erodibility and settling velocity are difficult to predict because physical and biological effects fundamentally impact them over short scales and feedback on each other. Primary motivations (Work by L. Schaffner, VIMS) Higher energy, sediment transport disturbs benthos Lower energy, sediment biologically processed York River – Chesapeake Bay:

In the upper York River estuary, disturbance by sediment transport reduces macrobenthic activity and sediment layering is often preserved. In the lower York, layering is more often destroyed by bioturbation.
