HydroCAD Modified Rational Method


Does anyone know if HydroCAD will create a hydrograph using the modified rational method and if so can it be created using typical storm durations Tc, 1.5Tc, 2Tc, etc?


RE: HydroCAD Modified Rational Method

Yes it can. But so can you using pencil and paper or a spreadsheet.

RE: HydroCAD Modified Rational Method

You can set the rise and fall rate (as a factor of Tc) on the Calculation Settings screen.

For details please see www.hydrocad.net/rational.htm
