Laboratory experiments were conducted in smooth trapezoidal channel with side slope 1:1 to measure boundary force and shear stress. Preston tube is used to estimate contribution of wall and bed shear stresses. Available formulas for estimation of boundary shear were evaluated and new formulas were presented. The effect of aspect ratio on wall and bed shear stresses was determined. Results showed that ratio of wall shear force to total shear force decreases as aspect ratio increases.
