ORGANIZED HORIZONTAL VORTICES AND LATERAL SEDIMENT TRANSPORT IN COMPOUND OPEN CHANNEL FLOWS

Direct Numerical Simulation of Sediment Transport in a Horizontal Channel

Analysis of Velocity Lag in Sediment-laden Open Channel Flows

Laboratory experiments have recently confirmed that the streamwise particle velocity is largely less than that of the fluid in sediment-laden flows. This velocity lag is investigated analytically in the present study based on the drag force exerting on a particle in the presence of other neighbors. The normalized drag force or the hindrance coefficient is found generally dependent on the partic...

The Effect of Convergence and Divergence on Flow Pattern and Sediment Transport in Lateral Intakes

Water supply at a desired rate at any time to meet the water requirements regardless of river discharge must be considered in the general design of intakes provided that the needs do not exceed the river flow. Due to the lack of necessary information in this field and the importance of sediment transport to the lateral intakes at river bends, this study aimed at understanding the mechanism of t...

one-dimensional numerical model of cohesive sediment transport in open channel flow

cohesive sediment transport remains a complicated subject that hydraulic engineers are frequently faced with in water-related engineering problems. this is primarily affected by the macroscopic aspects of water-sediment system characteristics. in this paper a 1-d mathematical model was developed to be employed in predicting the cohesive sediment transport under simultaneous conditions of erosio...

Electrical Resistance Tomography for Suspended Sediment Measurements in Open Channel Flows Using a Novel Sensor Design

Electrical Resistance tomography (ERT) has been previously employed to measure sediment concentrations in liquids (Bolton et al. [1], James et al. [2], Qiu et al. [3]), and linear sensors were the first type of sensor employed in previous tomographic applications (Qiu et al. [4]). However, ERT has mostly been used in cylindrical vessels or pipes with a circular sensor around the area of interes...
