Parts of Watershed Missing in QSWAT+ Delineation

[Daff gul]

Hello everyone,

I’m using QSWAT+ and noticed that after I drew the outlets during the watershed delineation stage, some parts of my watershed are not included in any of the subbasins. What could be causing this problem? I think one reason might be that the DEM (Digital Elevation Model) data near the ocean show lower elevation variability compared to inland regions, which might affect the delineation process.

Please let me know if you have any suggestions for how to solve this issue.

I’ve attached the screenshot.

Thank you!
