Might be an easy one (yes or no) :
When seeking a volume from the Modified Rational Method,the calculation is performed at multiple durations with corresponding intensities to produce a series of trapezoidal hydrographs.
Once the allowable discharge is subtracted the hydrograph with the greatest volume is then your critical storm duration for that analysis.
But do you check for duration < time of concentration (e.g. duration of 5 min while the tc is 15 minutes) ?
