Good day!

I’m having an issue with my land use data between QGIS and the SWAT+ Editor. The land use class “WATR” that I assigned during HRU creation is automatically transformed into “WETW”, which uses different parameters.

I already tried adding a WATR entry in the SQLite database, but it didn’t work. I also tried modifying the WETW parameters, but the problem still persists.

Moreover, my BSVG land use is also gone in SWAT+ Editor but it is in my QGIS Report. Areas too are not matching in my calculate geometry in QGIS. Why is that so? 

I’m not sure how to resolve this, as I’m still new to the software. I want to learn more about SWAT+, but self-learning is difficult when I can’t find answers to these issues. I hope someone can help. Thank you.

Dear QSWAT+ experts,
I am experiencing the same issue that Lanz reported. The land-use code “WATR” is being changed to “WETW,” and “BARR” is being converted to “Slice.” I would greatly appreciate your assistance and look forward to any guidance you can provide.
