Flow (Q) in an open channel, such as a swale, may be calculated using Manning's equation:
Where:
Where:
- Q = the flow in the swale (m3/s)
- A = the cross sectional area of the swale (m2)
- P = the wetted perimeter of the swale (m)
- S = the longitudinal slope (m/m)
- n = Manning's coefficient (dimensionless)
