Description
The SCS (U.S. Soil Conservation Service) Curve Number (CN) is invalid for soil with ID <>. The CN must be between 0 and 100.

Suggestions
The model infiltration method and its parameters are defined in the TUFLOW soils file (.tsoilf). When using the SCS infiltration method, in the .tsoilf, each soil ID must have a corresponding CN and SCS initial abstraction ratio. Ensure that soil ID <> has an CN between 0 and 100.
Please refer to the TUFLOW Manual for more information on the SCS infiltration method.
