Abstract:

A computer-oriented procedure is described to develop rating tables for side channel spillways. The procedure includes three sets of computations which have to be performed iteratively for each reservoir water surface elevation. The first set of computations determines the discharge per unit length over a submerged spillway; the second uses the singular point method to locate the control section for a given pattern of spatially varied flow in an open channel of given shape, roughness, and bed slope; and the third computes the water surface profile in the given channel for spatially varied flow. A simple illustrative example is presented to demonstrate the application of the proposed methodology.
