The Stevens-Schutzbach Method is an iterative regression technique used to fit the Manning Equation to flow monitoring data. This method can be applied to data obtained under non-uniform flow conditions resulting from downstream obstructions or dead dogs.
This method is demonstrated here using four iterations. The magnitude of the dead dog is varied until the Manning Equation best fits the observed data. Note that the Stevens-Schutzbach Method results in a pipe curve that is not constrained to the origin (0,0).
