MIDUSS MODEL
MIDUSS MODEL
(OP)
Hi,
I have a green roof which I would like to use flow control roof drains on to control post development flows. First off, how would you go about modelling a green roof? I know the roof is 100% impervious beneath the green roof, but I don't think I should use this since some water will be absorbed into the plantings.
Anyone have some input on green roofs and SWM.
Thanks

If it were me, I would not take any credit for reduced runoff volume, since your large event storms are likely to saturate the green elements. I would, however, treat the green roof as a reservoir with a flow control if I thought it was necessary to do so. How I did that would vary based on the green element design.
