Abstract

This paper investigates the impact of floodplain vegetation on the shear layer in the one-dimensional (1D) apparent shear stress model for compound openchannel flows. To obtain the mean flow and turbulence structures of the compound channel flows, the three-dimensional (3D) Reynolds stress model is used. The friction slope and interfacial eddy viscosity due to interfacial shear are evaluated and compared with values suggested previously. The impact of proposed interfacial eddy viscosity on the backwater profiles for compound channel flows with and without vegetation on the floodplains are also discussed.
