Velocity data from a large test channel were used to determine the distribution of depth-averaged velocity and shear stress on the side slope of both straight and curved channels. From the side slope velocity and shear stress distributions, riprap size was determined from the toe of the slope to the water surface. The location where the maximum riprap size is required varied from the toe of the slope in straight channels to the side slope in curved channels.
