Abstract : - To quantify the relationships between resuspension of fine material in the shelf by wind waves, tidal channels hydrodynamics, and sediment supply to coastal marshes. - To develop predictive, high-resolution models for the hydrodynamics and sediment dynamics of tidal channels in muddy coastal environments - To develop methods to predict the long-term evolution of tidal channels in muddy coastlines as a function of sediment availability, hydrodynamics, and climate change. OBJECTIVES To determine the feedbacks between waves, tidal fluxes and tidal channels in muddy coastlines To link the geotechnical properties of sediment substrates to the spatial and hydrodynamic characteristics of tidal channels To develop new morphological indicators of tidal flat morphodynamics that can be easily derived from remote sensing images. To link these indicators to mechanical properties of tidal flat substrates To compare the results of the MURI project Mechanisms of Fluid Mud Interactions under Waves to wave measurements at the shoreline. To integrate high resolution hydrodynamic measurements within ongoing research activities at the Willapa Bay Tidal Flats DRI location.
