Wet detention pond - Channel protection / water quality outlet configuration
Link to this table
| Design methodology | ||||
|---|---|---|---|---|
| 1-yr 24-hr Instantaneous volume | 1-yr 24-hr routed (R124) | 1/2 Pre-development 2-yr 24-hr peak Instantaneous volume | 1/2 Pre-development 2-yr 24-hr peak routed (R224) | |
| Orifice diameter (inches) | 10.5 | 6.9 | 10.0 | 11.6 |
| Oriface elevation (ft) | 105.0 | 105.0 | 105.0 | 105.0 |
| Surface area at orifice elevation (ac) | 0.6 | 0.6 | 0.6 | 0.6 |
| Peak discharge per design event (cfs) | 6.4 | 2.1 | 5.8 | 5.8 |
| Peak water elevation per design event (ft) | 107.9 | 108.2 | 108.7 | 108.5 |
Note that the routed method for the 1-year design (R124) is much less than the Instantaneous volume due to the more constricted orifice.
