V-Notch weirs are defined in StormCAD
by the following equation:
|
Q |
= |
flow (cfs, cms) |
|
C |
= |
coefficient of discharge (US, SI forms) |
|
g |
= |
gravitational constant |
|
è |
= |
angle of notch (degrees) |
|
H |
= |
head above the bottom of the notch (ft, m) |
H is measured from the water level to the bottom crest of the weir.
