    Hi Mattias -

    Any time we get a "key error" in the terrestrial models, it usually means that there is a mismatch between values in your land use raster and the values in your biophysical table. Is there an LULC raster class with a value of 12 that there is not an entry for in your biophysical table? In this case, the model is trying to build a Curve Number raster and appears not to find CN values for lucode 12 in the biophysical table.

  • Hi,
    the problem was with Hydrological group map. there was a HSG class coded with 12. After reclassifing it, the model works correctly.
    thanks for your help
  • Thank you Mattias & swolny changing in HSG class coded works for key error encountered:12.
