Abstract

The shear stress distributions in open-channel flows with favorable pressure gradients are predicted by making use of the equation of motion and continuity equation under the assumption that the ratio of the friction velocity U to the maximum velocity U_max is almost constant in the streamwise direction. The values of the predected shear stress are smaller than those of uniform open-channel flows and also decrease with a decrease of the normalized pressure gradient parameter. The predected shear stress distributions are in a good agreement with the experimental values.
