Figure 7.

Spatially-averaged of flow parameters changing immediately behind the models. (a) Viscous shear stress changes with distance from the bed normalized by the boundary layer thickness ($\mathrm{\delta }$). (b) Variations of Reynolds shear stress normalized by shear velocity ($U_{\tau }$). (c) Reynolds stress variations from the bed. It was observed that the total shear stress was constant across the layer and equal to the wall shear stress (${\tau }_w$).
