Primary motivations
New NSF project Improved Observation, Analysis
and Modeling of Fine Sediment Dynamics in Turbid,
Biologically Active Coastal Environments Underst
anding 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.

Lower energy, sediment biologically processed
Higher energy, sediment transport disturbs benthos

Map showing real-time observing sites along with
example x-radiographs (from L. Schaffner). 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.
