Equations Developed by Chezy and Manning The first recognized and most lasting “resistance” formula for steady state, open-channel flow is credited to Antoine Chezy.

The chapter on flow through open channels, for example, gives the Chezy formula with Bazin's values for the coefficient, but takes no note of the elaborate, and more generally recognised ...

To determine the flow in pipes and channels the author adheres to the old Chezy formula and gives tables of values of the coefficient C.
