Abstract

The effect of wind shear stress on the flow in an open channel is investigated for the case where wind and water move in the same direction. The investigation is based on experimental data obtained with a unique wind water tunnel. A method is developed by which it is possible to separate water surface shear stress and bottom shear stress. . The difference between bottom shear stress calculated by this technique and water surface shear stress agrees well with the shear stress predicted from the velocity distribution in the water. A method is given by which the water surface shear stress may be calculated. The shear stress coefficient of the water surface is significantly lower than that for the case of initially standing water. The experimentally determined surface stress agrees with that calculated from the air velocity distribution.
