Q = K/n * A * R^(2/3) * S^(1/2)

Q = discharge (m^3/s or ft^3/s)
K = 1.486 for USCS units, 1.0 for SI units
A = Cross-sectional area of flow (m^2 or ft^2)
R = hydraulic radius = A/P (m or ft)
P = wetted perimeter (m or ft)
S = slope of hydraulic surface (m/m or ft/ft)
n = Manning's roughness coefficient
