Abstract: In this study, the dynamic behavior of bed-load sediments under unsteady flow conditions is experimentally investigated and discussed. A series of experiments were conducted in a 6-m-long laboratory flume with naturally ...

Abstract: Natural channels are seldom straight and commonly take sinuous patterns with turbulent and strongly three-dimensional (3D) flows in the bends. A 3D hydrodynamic model [Reynolds-averaged Navier-Stokes (RANS)] with major 3D ...
