摘要:
An analytical approach to the description of the radial bed topographies in a steady state, fully developed alluvial channel bend with uniform bed material with different sediment concentrations is presented. The approach is based on the conservation of moment of momentum and the modified velocity profile due to sediment suspension. Bed topography simulation is verified by laboratory data. Sensitivity analyses were also performed to study the effects of sediment concentration on transverse bed profiles.
