Objectives: 1. To use our process-based parameterization of surficial seabed disaggregated inorganic grain size (DIGS) distributions to infer the extent of flocculation during deposition on energetic tidal flats. 2. To use time series of in situ suspended sediment properties, waves, and currents. to improve understanding of how turbulence, sediment concentration, and cohesion affect the size-dependent depositional flux of sediment to the seabed on energetic tidal flats. 3. To improve understanding of how sediment texture, cohesion, and sorting in the seabed affect the size-dependent erosional flux from the seabed on energetic tidal flats.
