Hi @felipebenra -
Ok, so you’ve checked that there is not a value of 34 in your land cover raster that is not included in the biophysical table. Since this is the curve number, which is linked to the hydrologic soil group raster, also check that there is not a value of 34 in your soil group raster. The values of soil group for this model can only be 1,2,3 and 4, but sometimes there are other values assigned to soil groups. If this is what’s happening, you’ll need to reassign the soil group raster values of 34 to one of the allowed classes of 1-4. If this isn’t what’s happening, then please do provide your data and I’ll check it out.
