Mud and Sand Suspension
Wave- and current-supported gravity flows (WCSGFs) are one of the chief participants in shaping the marine geomorphology. The focus of present study is to investigate the role of alongshore currents on the dynamics of WCSGFs, considering the change in sediment availability through sediment mass exchange. A direct numerical simulation (DNS) study is conducted for a steady, turbulent, particle laden channel flow with a gentle transverse slope. Our objective is to get a clear interpretation of the flow structure of CSGFs and to evaluate the coupling between current induced BL turbulence and suspended sediments for a various bed erodibility parameters.
