Manual creation of IDF curves

Currently the Rainfall Manager only allows to create IDF curves by entering the coefficients for the Montana or Shermann method. The support of the manual definition of the IDF curve ( intensity/duration) would be a nice feature!

Hi,
I am wondering of the best way to retrieve the intensity once the curve is entered manually. To have an intensity from a duration, it is necessary to perform an interpolation between two points. In that case, what is the best.

• linear interpolation ?
• using Montana to perform the interpolation.

If using Montana could be the best, I think the solution could be to add the capabilities to import the curve by calculating the Montana coefficient for all intervals from intensity/duration pair.

I think both options would useful, especially the capability to import the curve by calculating the Montana coefficient for all intervals from intensity/duration pairs.
