Abstract

3D numerical computations are performed to simulate the shallow water flow through an array of non-submerged cylinders occupying a circular area in the middle of the domain. A hydrodynamic model capable of capturing the free surface positions is developed with the SST (shear strain transport) k-ω turbulence closure. The model is first verified and validated against experimental data available in the literature. It is demonstrated that the present model can predict both the average velocity and turbulence structure well. In addition, both cylinder-scale flow as well as patch-scale flow can be well reproduced. The velocity field and distribution of bed stress are then analyzed to study the flow patterns and sediment deposition with different solid volume fractions and water depths.

Keyphrases: hydrodynamic, non submerged vegetation, shallow water flow, turbulence model
