I am trying to use HEC-GeoHMS to build a model for HEC-HMS. The method I will be using for loss is SCS CN method. I already have the CN grid for the site. But I could not find a place in HEC-GeoHMS to provide the CN grid. I have been trying to figure out this since long time, but was not successful. I am using HEC-GeoHMS for 10.2.2 ArcMap.
I would really appreciate any help on this.
I tried with this but was not helpful. No place to assign CN Grid.
