I have been running SWY models for 10 watershed in Ethiopia. Only one watershed was successfully run. For rest of watersheds, I got different errors.
The inputs difference among different watersheds are biophysical table and DEM.
Thanks for sharing these logs. Please let us know if you have the same issues when all the files are stored locally on your machine. It could be something similar to post I found, which talks about how some Cloud Storage only allows sequential writing and that TIFF writing requires random writing.
