Is there away to run hydroCAD to adjust for greater runoff volume when comparing to Green-Ampt method of predicting runoff?

When using the SCS/NRCS method in HydroCAD, runoff volume is determined by the CN value, the antecedent moisture condition (AMC), and the Ia/S ratio. In theory, any of these could be adjusted for specific purposes, but the default values are generally recommended.

Note: Other parameters will effect the peak flow, but these are on the only ones that effect the volume.
