Quick Reference

An equation for calculating the average velocity of water flowing in an open channel, proposed in 1897 by H. E. Bazin (1829–1917). It relates the Chezy discharge coefficient (C) to the hydraulic radius (r) and a channel roughness coefficient (k1) by the formula: C = 157.6/[1 + (k1/r1/2)]. Other more complex formulae have also been proposed. See Chezy's formula.
