Vertical Transfer in Open Channel Flow

Aeolian and subaqueous bedforms in shear flows

“…Both the sediment flux and the saturation length are much larger than that of bed-load, by a factor D/d. It has been measured [38][39][40][41] and shown to scale as L sat ∝ u * D/V fall [42]. Bed-load is the dominant mode of transport when ripples form.…”

Suspended Sediment‐Induced Stratification Inferred From Concentration and Velocity Profile Measurements in the Lower Yellow River, China

“…The effect of sediment diffusivity may be separated from density stratification by pairwise comparison of concomitant velocity and concentration profiles. The value of sediment diffusivity β is frequently debated (Murray, 1970;Coleman, 1970;Jobson, 1970;…”

Vertical sediment concentration distribution revisited with shear-induced diffusivity: An explicit series solution based on homotopy analysis method

“…Graf and Cellino [23] experimentally determined β < 1 without bedform and β > 1 with bedform over an erodible sediment bed. However, experimental results revealed that β ≈ 1 for finer sediment particles only, and β < 1 for coarse sediment particles [41,49,50]. Thus, the assumption β ≈ 1 may not be physically reasonable; so in our model, we assume that β 1.…”
