Hi @DGowtham ,
I was able to find this resource for the HYSOGs250m raster:
https://daac.ornl.gov/SOILS/guides/Global_Hydrologic_Soil_Group.html
In this document they have a table for what the values relate to:
From this, I think that our guidance from the UG can be used.
There’s also this post from @swolny about converting soil groups for the Seasonal Water Yield model: Urban Flood Risk Mitigation model - converting dual soil-groups (e.g., A/D) to 1-4
Cheers,
Doug
