Abstract: A probability density function (PDF) of the instantaneous bed shear stress in a turbulent flow is derived in this paper. It is argued that the shape of the PDF is similar to the PDF of the instantaneous drag forces on bed ...

Abstract: Bed protections are usually characterized by low-mobility transport conditions and nonequilibrium turbulence profiles. As the present knowledge of the influence of turbulence on stability of cover layer units is minimal, ...

Abstract: Data collected from measurements in a two‐dimensional (2D) wave flume with a trapezoidal bar on a horizontal bottom are used to test the numerical model previously developed by the writers. The experiments were performed ...

Abstract: Transverse exchange of momentum between the channel and the floodplain in straight uniform compound channel flow is considered in this paper. This process results in the so-called “kinematic effect,” a lowering of the total ...
