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

Abstract

Our long term goal was to develop numerical simulation techniques for generating accurate predictions of sediment transport and bed evolution in the coastal zone at horizontal scales of 10s of meters or less. Our objective for this year was to lay the groundwork for simulation of flow over buried objects using the Numerical Wave Tank model of Grilli to drive the Navier-Stokes LES code of Zedler and Street.
