Clarification on Manning's Values in landcover_mannings.txt for Head Loss Downscaling

[dharanidharatdd]

Hi,

In the landcover_mannings.txt file used for head loss downscaling in the example case, the Manning's values differ from the standard (e.g., water is usually 0.035 but listed as 10). Are these values Manning's constants (n) or some other derived parameter? If they are derived, could you guide me on how to calculate them?

Thanks!
