Large Eddy Simulation of Sediment Transport in the Presence of Surface Gravity Waves, Currents and Complex Bedforms

Abstract

Our long-term goal is to develop numerical simulation techniques for generating accurate predictions of sediment transport in the coastal zone. Our current main focus is building upon earlier work that produced quantitatively accurate hydrodynamics and producing a tool for sediment transport modeling. Our tool is a large-eddy simulation [LES] in three dimensions and time, at scales on the order of meters, and in the presence of waves and a current. Our numerical analysis objectives include accurate representation of the flow near rough boundaries, creation of improved models for the unresolved or sub-filter scale [SFS] motions and sediment transport, and optimization of the computer code for multiprocessor computer systems.
