Abstract

Flow in an open channel is understood to be flow of a liquid with a free surface. Flow is uniform if no change in depth takes place; the depth occurring at uniform flow is referred to as the normal depth. In a rectangular channel with a free overfall the flow far upstream from the overfall is uniform. As the free overfall occurs, the depth of flow decreases until a minimum depth occurs at the overfall itself.
