Sediment Pick‐Up Functions
Publication: Journal of Hydraulic Engineering
Volume 110, Issue 10
Abstract
Experimental research has been performed to determine the sediment pick-up by a uniform flow without initial sediment load. A sediment lift was designed by which the sediment particles were moved upwards at a constant rate through a circular opening in the flume bottom. Five types of bed material (sand) have been used with D50-values in the range 130-1500μm. The mean flow velocities were in the range 9.5-1.0 m/s. The experimental results have been used to derive an empirical pick-up function. The results have also been used to evaluate several existing pick-up functions. Finally, the proposed empirical pick-up function has been applied to predict the bed-load and suspended load transport. In the latter application the proposed function has been used as a bed-boundary condition in a mathematical model for suspended sediment transport.
