“…A proper selection of the particle diffusivity coefficient D in the mean model equations (19) allows us to predict the anti-dune transition (solid line in Fig. 3) in the wide range of relative roughness 10 −3 ≤ δ 2 ≤ 0.5 in agreement with numerous experiments, see [19,20,39,51,67] and references there in. The linear stability analysis by Vesipa et al [76] originally reproduced the anti-dune convective-absolute transition with Fr ≥ 1 and δ 2 ≤ 3.5 × 10 −3 .…”

“…In this section we show that particle diffusion is a necessary physical process in the developments of anti-dunes with critical Froude [39,51] and references in [19,20,62,67]. UMA and DMA denote two-dimensional upstream and three-dimensional downstream migrating anti-dunes, respectively, and TRAN corresponds with transition bed forms (mostly standing waves).…”

“…The full non-linear numerical simulations are in excellent agreement with the theoretical solutions. We conclude highlighting that the proposed depth-averaged formulation explains the developments of upstream migrating anti-dunes in straight flumes since the seminar experiments by Gilbert (1914). …”

The doctoral research of Albert Frank Shields on sediment movement conducted in Technischen Hochshcule Berlin becomes a legend that is most often referred by many authors and has initiated a sizable number of researches over last seven decades. The Shields diagram is famous due to its application in ascertaining the threshold of sediment motion that is an essential prerequisite for the estimation of sediment transport in an alluvial stream. Since his pioneering work, numerous attempts have so far been made to study the sediment threshold both experimentally and theoretically. This paper presents a comprehensive state-of-the-art review of the important laboratory experimental and theoretical investigations on sediment threshold under steady stream flow highlighting the empirical concepts, hydrodynamic background and the mathematical treatment of the problem. The role of the turbulent bursting on sediment threshold is also discussed.

“…Investigation of sediment transport started from the sediment transport flume experiments carried out by Gilbert [1] , and then a large amount of investigation results have been presented by many scholars [2,3] . In terms of the researches on sediment transport capacity, there exist three stages: (1) The first one is the preliminary stage, when some qualitative exploration and experienced analysis were performed before the 1950s.…”

As one of the most important components of river mechanics, sediment transport capacity of sediment-laden flows has attracted much attention from many researchers working on river mechanics and hydraulic engineering. Based on the time-averaged equation for a turbulent energy equilibrium in solid and liquid two-phase flow, an expression for the efficiency coefficient of suspended load movement was derived for the two-dimensional, steady, uniform, fully-developed turbulent flow. A new structural expression of sediment transport capacity was achieved. Using 115 runs of flume experimental data, which were obtained through two kinds of sediment transport experiments in the state of equilibrium, in combination with the basic rheological and sediment transporting characteristics of hyperconcentrated flow, the main parameters in the structural expression of sediment transport capacity were calibrated, and a new formula of sediment transport capacity for hyperconcentrated flow was developed. A large amount of field data from the Yellow River, Wuding River, and Yangtze River, etc. were adopted to verify the new formula and good agreement was obtained. These results above contribute to an improved theoretical system of river mechanics and a reliable tool for management of rivers carrying high concentration of sediments. hyperconcentrated flow, turbulent energy equilibrium, efficiency coefficient, sediment transport capacityIn the Yellow River, hyperconcentrated flood occurs frequently during the rainy seasons. Both the historical maximum concentration of 1600 kg/m 3 and the mean annual amount for sediment transport of 1600 million tons are the highest values worldwide. According to the statistical results coming from the sedimentation bulletin of Chinese Rivers and the Yellow River 1)2) , and the analysis of the field data from Tongguan, Huayuankou, and Lijin Hydrological Stations along the
