Abstract

For uniform bounded flow conditions, much of the hydraulic resistance may be attributed to grain roughness and flow characteristics with further accounting for other forces. The resistance to flow by the channel boundary is manifested in the form of distribution of boundary shear along the periphery. In the present work, the validated equations of shear stress distributions across the boundary of main channel and roughened flood plain are analyzed and tested for compound channel having high width ratio of 15.75 and their flow conditions using fresh lab data recorded for this purpose as well as for FCF data for a better comparison. Keywords: open channel, compound channel, boundary shear, roughness, overbank flow.
