Allow SOIL values < 0.15
The Rural Runoff estimate tool in MDSUDS does not allow values of SOIL below 0.15.
The UKSUDS greenfield runoff tool defaults to a value of SOIL=0.1 where SoilType=1
This produces a significant difference in results. This difference results from using values of SOIL from FSR vs Wallingford Procedure and FSSR7
It would be better if the MDSUDS tool allowed values of SOIL down to 0.1 for compatibility, and if the default values were standardised across the industry.
