Description	Other Turbulent structures are investigated experimentally in compound open channel flows with roughness on the flood plain. The main-channel velocity is significantly decelerated and the secondary currents in the main channel are developed due to the roughness on the flood-plain. An increased velocity gradient results in a remarkable increase of the bed shear stress near the flood-plain edge. The apparent shear stress on the junction interface and the turbulence intensity in the main channel. These features are well predicted by the numerical calculation of the depth-averaged momentum equation.
