Good and consice information. It was easy to understand even for a beginner. A slight problem are the different QGIS Version, since neither Saga/Saga next gen nor PCRaster work with every version, so it would be nice if you could name the last Qgis version you used for the PlugIns without. Problem. Have a nice day. Cheers.
@@HansvanderKwast thank you, yeah it seems to be depending on a stroke of luck, if a plugin works... but its still one of the best/easiest to use open source GIS software.
In the workflows that I use the catchments are determined by all contributing pixels. So there's no option to use less than all. However, if you use the approaches to derive all catchments or subcatchments, you can then add a condition with thresholds.

Good point. In my recent videos, I've added the version of QGIS used in the video to the description.

Thx for this explanation !!
Excellent video, thank you very much!
How can we set a threshold value for the maximum catchment area so that we avoid having too large catchments?
In the workflows that I use the catchments are determined by all contributing pixels. So there's no option to use less than all. However, if you use the approaches to derive all catchments or subcatchments, you can then add a condition with thresholds.
Could you provide details of stream and catchment Delineation for flat area?
If the area is too flat, you probably need to do it manually, based on expert judgement.
Can you make a video to delineate urban watershed.
