Boundary shear stress analysis in smooth rectangular channels

This study reports on experiments concerning the boundary shear stress and boundary shear force distributions in a smooth rectangular flume. Nonlinear regression-based equations are derived from experimental analysis to give the percentage of the total shear force carried by the walls and mean wall and bed shear stresses around the wetted perimeter as functions of the ratio of channel width to perimeter as functions of the ratio of channel width to channel depth. © 2006 NRC Canada
