Calculate Channel Velocity (V) for Any Channel

Hydraulic radius of channel (R=A/WP)

Slope of energy grade line, rise/run,(S)

Manning's Roughness Coefficient (n)

Channel Velocity, V

mps

R=A/WP - Hydraulic radius of channel
S - Slope of energy grade line, rise/run
n - Manning's Roughness Coefficient
V - Channel Velocity
