Chezy’s equation is rarely used directly, but it is the basis for several other methods, including Manning’s equation. Chezy’s equation is:
| |
Q |
= |
Discharge in the section (m 3 /s, cfs) |
| |
C |
= |
Chezy’s roughness coefficient (m 1/2 /s, ft. 1/2 /sec.) |
| |
A |
= |
Flow area (m 2 , ft. 2 ) |
| |
R |
= |
Hydraulic radius (m, ft.) |
| |
S |
= |
Friction slope (m/m, ft./ft.) |
