Smooth rectangular open channel flow is a benchmark for studying river hydraulics and sediment transport.Such a flow is more complicated than the classic boundary layer flow at least in two ways: (i) the maximum velocity occurs below the water surface, which is called the velocity-dip phenomenon;and (ii) the velocity distribution is affected not only by the channel bottom but also by the side-walls and the free surface.
