Predicting the Evolution of Tidal Channels in Muddy Coastlines
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. Measure the supply of sediments to a Louisiana salt marsh as a function of wind waves. Determine the hydrodynamics of the tidal channels dissecting the mud flats of Willapa Bay, WA. Apply, test, and validate a high resolution hydrodynamic-sediment transport model in tidal channels and determine the short-term evolution of the channels and the supply of sediments from the shelf. Integrate the short-term results of high resolution numerical models in long-term models of tidal channels and mudflat evolution. Link the transport of sediments to salt marshes via tidal channels to the resuspension of fine sediments in the adjacent shelf. Compare the results of the MURI project "Mechanisms of Fluid Mud Interactions under Waves" to measurements of sediment concentration in a nearby marsh channel. Integrate high resolution hydrodynamic measurements in tidal channels with ongoing research activities at the Willapa Bay "Tidal Flats" DRI location.
