Time of travel of elementary waves in prismatic channels with gradually varied flow is expressed by two parametric equations. The first of these equations gives the travel time over a reach. The second equation, which is analogous to Bakhmeteff's backwater function, gives the appropriate flow parameters of the reach. Parameters are the actual and normal Froude numbers. The simultaneous solution of the two equations furnishes the initial conditions for flood routing computations using the method of characteristics.
