This weir type is provided as a convenience. It is a broad crested weir with side slopes applied to each end.
The effect of varying the side slope is to vary the weir coefficient. Flow is computed based on:
Where:
|
Q |
Discharge in cfs |
|
c |
0.6 |
|
L |
crest length (ft) |
|
H |
Stage above crest (ft) |
|
tan(theta) |
side slope xH:1V |
