Hydrological Theory

User Defined Storms

The user defined Mass Rainfall Distribution function is defined in exactly the same way as for the Huff storm but with the difference that the number of points is not limited to 51 to define the curve.  Since the initial and final points must have values of 0.00 and 1.00 respectively this means that there can be up to (Npts-1) equally spaced segments in the definition of the Mass Rainfall curve.

A number of popular rainfall distributions are described in *.mrd files which are included with MIDUSS.  These include the various SCS 24-hour and 6-hour storms and regulatory storms such as Hurricane Hazel (Southern Ontario, Canada) and the Timmins storm for more northerly parts of Ontario.  These files are simple text files and can be printed out to show the values used.
