I'm using Modified Rational and I have created IDF curves based on my local Hydrology Manual.
I want to run a 50-year, 24 hour storm event, calculating the peak Q based on a calc'd Tc
Under Project Options - I set the Modified Rational Method Storm Duration" to 1440
under analysis options, I set the analysis duration to 1 day
when I run the model, I find that the program returns a reasonable Tc, but instead of calcing the peak flow from that Tc, it returns a rainfall intensity and resulting Q of the 24-hr average
