Overflow
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 |
