The Hydrologic Soil Group is the number one interpretation / property requested on WSS. This has consistently been the case for many years. In order to determine the hydrologic soil group from modeled soil maps, the following soil properties would need to be predicted:
Ksat RV of the least transmissive horizon in the 0-100 cm depth range
Top depth RV of the first water impermeable restriction (fragipan; duripan; petrocalcic; ortstein; petrogypsic; cemented horizon; densic material; placic; bedrock, paralithic; bedrock, lithic; bedrock, densic; or permafrost)
Minimum top depth RV of the water table for all months (wet state in the Component Soil Moisture table)
