Artificial Turf- Runoff Calculation
Artificial Turf- Runoff Calculation
(OP)
My client wants to install artificial turf by eliminating existing natural grass. I was requested to calculate and proove new development will not increase the runoff from the site.
Turf has a impermeable bed with a perforated treches connected to a catch basin.
Please help if some one has experience in this cal.
Thanks a lot!

RE: Artificial Turf- Runoff Calculation
Estimating the Tc is more complex. This will depend on the travel time through the turf, bed, and trench system. Depending on the exact design, you may be able to model this as a sub-surface "pond".

RE: Artificial Turf- Runoff Calculation
The peak flow will depend on how quickly this volume is released. If you have enough storage available in the base, you can control the peak discharge by deliberately restricting the outlet. In effect, the sub-surface storage becomes a detention pond.
Of course, this will effect the peak timing, which will effect how your discharge combines with adjacent flows to the same drainage system.

And don't, don't, don't use the area under the field as the detention facility. This may cause the field to float during rainfall events. You want the facility to quickly and effectively drain to another area for stormwater control.
