Previous research has mainly focus... WebIn the model, the vertical flow structure, which plays an important role in the formation and evolution of sand waves, is resolved by solving three dimensional (3D) Reynolds-averaged Navier-Stokes (RANS) equations with a k-ε turbulence closure. The bed slope effect on the bedload transport is considered in the model.
