Simulation of suspended sediment transport in vegetated open channel flows with a k-ε turbulence model

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

A k-ε turbulence model is employed, coupled with special boundary conditions for dissipation at the free surface, to numerically simulate uniform open-channel flows through vegetation. For the calibration of some parameters involved in the model, predicted vertical profiles of spatially averaged mean velocities, standard deviations of the velocity components, and eddy viscosities are compared with experimental observations. The computed velocity and turbulence fields are then used to solve the vertical sediment diffusion equation and hence compute the equilibrium vertical distribution of suspended sediment. Numerical integration of suspended sediment and velocity profiles allows for the estimation of sediment transport rates, and thus sediment transport capacities under different flow conditions and vegetation characteristics. Numerical results are compared against computations for non-vegetated channels.
