WebManning’s Formula. 1. Bazin Formula. This formula is developed in MKS units. The Basin formula is given by: K = Bazin’s Constant; m = Hydraulic mean depth or hydraulic radius. The bazin’s constant is dependent on the roughness of the channel surface. More the roughness of the surface, higher is the value of Bazin’s Constant. Web1. Chezy’s Formula. French engineer Antoine Chezy derived Chezy’s formula in the 1760s to study the flow behavior. The formula is given by: V = C. R ½ S ½ (Eq.1) Where C= …
