Abstract: The hydrodynamic response of turbulent flow in an open channel to the bed and bank roughness heterogeneity was demonstrated. Roughness‐induced secondary currents were numerically simulated in the presence of the vortex ...

Abstract: Steps leading to the numerical study of the hydrodynamic behavior of a compound open channel are described. The method uses an algebraic stress model imbedded, together with an energy‐dissipation model, in a parabolic ...

Abstract: The hydrodynamic response of the turbulent flow in a compound rectangular open channel to the flood‐plain depth, roughness, and symmetry, and to the channel Reynolds number is demonstrated. The flow in the four basic ...

Abstract: Unstable patterns are identified in the results of numerical simulations of two cases of partly vegetated open channels, at the free unobstructed flow side of the shear layer that separates the unobstructed channel from ...

Abstract: The hydrodynamic response of turbulent flow in a compound wide rectangular open channel with a vegetated domain at the channel bank, in a channel corner and in a floodplain, to the vegetation density and diameter is ...
