Hi everyone, I’m encountering an error in QSWAT when running water delineation. The error says:

“Soil name TX047 (and perhaps others) not defined in usersoil table in database QSWATRef2012.mdb.”

I’m using a soil map from the FAO World Soil Map, and it seems that some soil classifications are not defined or linked in the usersoil table.

Has anyone experienced this issue before? Can you please send me the steps on how to create or update the usersoil table for this case? Any help would be greatly appreciated. Thank you!soil issue.png

After many attempts I decided to use the QSWAT+ instead of QSWAT, now i have successfully run my QSWAT+ without any error. there are youtube tutorials about it
