Abstract: The paper explores the use of the proposed compound channel Froude number in problems of water surface profile computation. It can be used not only to determine critical depth and to identify the flow regime in overbank flow but can also be substituted directly into the equation of gradually-varied flow. Two example problems are presented. The first involves water surface profile computation in a prismatic, laboratory channel with a flood plain while the second investigates water surface profile computations in a laboratory model of an alluvial river.
