Processes Affecting Exchange of Mud between Tidal Channels and Flats

The goal of our Tidal Flats research is to expand our understanding of the erosional and depositional processes that lead to exchange of mud between tidal channels and tidal flats. We also investigate the effect of sediment texture on sediment strength. Our research on Tidal Flats DRI had three primary objectives: 1. Improve understanding of how turbulence and sediment concentration affect the size-dependent depositional flux of sediment to the seabed on tidal flats. Based on our observations during the project, this objective has been broadened to include the effect of rainfall and runoff. 2. Improve understanding of how sediment texture and sorting in the seabed affect the size dependent erosional flux from the seabed on tidal flats. 3. Link our understanding of erosional and depositional sorting to spatial and temporal patterns of grain size on tidal flats.
