Dear Chris George and SWAT+ User Group,

I have completed the simulation work using QSWAT+ for my case study. The basin in my study area consists of approximately 21 sub-basins.

For further analysis, I am trying to obtain runoff component outputs (SURQ, LATQ, GWQ, and water yield) at the sub-basin level, similar to what is available in ArcSWAT. However, I currently only have water balance outputs at the HRU and LSU levels.

Could you help me, please?

SWAT+ does not use subbasins in any serious sense. You need to identify
the LSU which is the most downstream in each subbasin, and the outputs
from that LSU will be what you want.
