Abstract:

The long term goal is to develop a model which will predict local sand transport and bathymetric change due to waves and currents under time-varying conditions. Accomplishment of the long-term goal will require significant improvement of our understanding of the relationships between hydrodynamics and sediment motion near the seabed, as well as the development of models derived from our understanding of the relevant physical processes. An accurate prediction of local bedforms is necessary in order to describe the mixing processes which effect both the hydrodynamics and the sediment motion. A related objective is to characterize and predict the suspended sediment concentration in terms of the reference concentration and a vertical distribution function. This requires coupling between hydrodynamic forcing, bedform response and feedback, bedload sediment transport response, and the suspended sediment response.
