Predicting the Evolution of Tidal Channels in Muddy Coastlines
Abstract
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. To develop predictive, high-resolution models for the hydrodynamics and sediment dynamics of tidal channels in muddy coastal environments To quantify the relationships between sediment supply to tidal channels, resuspension of fine material in the shelf by wind waves, and sediment input from major rivers. Measure the supply of sediments to a Louisiana salt marsh and the short-term sediment deposition on the marsh surface. Apply, test, and validate a high resolution hydrodynamic-sediment transport model in a Louisiana marsh and determine the short-term evolution of the tidal channels and the erosion deposition patterns on the marsh platform. Integrate the short-term results of the high resolution numerical model in already developed longterm models of tidal channel 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. Share and merge the model and results with those of the MURI Research Group.
