Abstract

This paper presents a depth-averaged model for the numerical simulations of flow and sediment transport in open-channel flows with submerged vegetation. Since the flow structure and the concentration profile in the open-channel with submerged vegetation are different from those in the plain open-channel, the conventional methods of estimating the friction coefficient and sediment load should be modified. The vertical structure model with k-ε turbulence closure is used to adjust the relevant parameters in the depth-averaged model. The impacts of model modifications are provided and discussed. Using the developed model, flow and suspended sediment transport through submerged vegetation are simulated, and predicted results are compared with experimental data.
