Rainfall -to- I-D-F Curve procedure needs checking 1

[hardycrossfan]

I'm trying to convert NWS 24-hr rainfall data (east coast) into I-D-F curves. The application I'm using is asking for values rainfall depths for the 5, 15 and 60 min intervals.

Let me ask, should I be dividing the 24-hr rainfall depth (from NWS Hydro35 maps) BY 24x60x60...and then mulitplying the result BY either 5, 15, 60.. to get the required depths?

Careful!

Is it possible you are confusing rainfall depth, in inches, with rainfall intensity, in inches per hour ?

good luck
