Downstream - hydraulic geometry relations for stable sections and the regime theory equations, represent an inductive approach to stable channel design. This approach essentially duplicates the successful designs and forms a useful and popular method. The equilibrium - state experimental data from fourteen stable study reaches on five ACOP canals from Winter 1974 to Summer 1977 has been analyzed. The analysis includes screening of data to exclude non-uniform flow runs and derivation of at-station hydraulic geometry relations for water surface width, hydraulic depth, average velocity, energy gradient, Manning and Froude number as power functions of discharge. These relations are then used to extrapolate the values of these variables for the design discharge. Downstream - hydraulic geometry relations for the variables are developed from the extrapolated values. The downstream relations represent stable channel design equations applicable to the range of data analyzed.
