In this paper we study Exner system and introduce a modified general definition for bedload transport flux. The new formulation has the advantage of taking into account the thickness of the sediment layer which avoids mass conservation problems in certain situations. Moreover, it reduces to a classical solid transport discharge formula in the case of quasi-uniform regime. And as a particular ca...

Many formulas available in the literature for computing sediment transport rates are often expressed in terms of time-mean variables such as time-mean bed shear stress or flow velocity, while effects of turbulence intensity, e.g., bed shear stress fluctuation, on sediment transport were seldom considered. This may be due to the fact that turbulence fluctuation is relatively limited in laborator...

Vegetation provides habitat and nature-based solutions to coastal flooding erosion, drawing significant interest in its restoration, which requires an understanding of sediment transport retention. Laboratory experiments examined the influence stem diameter arrangement on bedload by considering arrays different mixed diameters. Bedload rate was observed depend turbulent kinetic energy, with no ...
