IDF Curves
IDF Curves
(OP)
Say you have a catchment and you know the maximum flow that can go through the pipes. Which IDF value would you state as the event that can flow through this network? I.e. say the intensity is 30mm/hr this could correspond to a 2 year 10min storm or a 100year 1 hr storm:

If there is no guidance on the storm frequency to use, pick what storm event you are comfortprable with.

If you're trying to back your way in to determine what the capacity storm is for your culvert, then solve for flow using Manning's or whatever, check inlet/outlet control, and plug that into the Rational Equation to determine capacity intensity. Then determine your Tc and read up on your idf curve to determine the capacity storm.
