WebThe Irish engineer Robert Manning presented an empirical formula for the mean velocity of a uniform, gravity-driven, fully developed, turbulent ow in rough open channels based on experimental data (Chow, 1959). Manning's formula is given by v = 1 n R 2=3 S 1=2 (assuming SI units) where n is the Manning roughness coe cient (s m 1=3). Values of ...

Iwagaki (Chow, 1959) found from experimental data that the coefficients 12.2 and 5.2 actually vary with the Froude number. He reasoned that as the Froude number increases, the stability of the free surface ...
