Hazen william c factor
A result of adjusting the exponents is that the value of C appears more like a constant over a wide range of the other parameters. The conversion factor k was chosen so that the values for C were the same as in the Chézy formula for the typical hydraulic slope of S=0.001. The value of k is 0.001 −0.04.
