This is one of the best tutorial videos about QGIS I have ever seen. Thank you for your effort.

I watched this tutorial during my final year at varsity in 2019 for a design project we had. 5 years later and I return to this tutorial for a big project in Africa. Hans, thanks for this brilliant and elaborate video, appreciate it dearly.

Hi Hans, everyone seems to have doubts and we are used to be in a kind of a rush, but I just wanted to let you know that we deeply appreciate the work that you have been doing. This video was exceptional; the language you used was concise, clear and it worked flawlessly for me. Thank you so much!

Super helpful video. Just starting out my GIS journey. This will save me heaps of time trying to manually delineate catchments and produce maps! Thank you!

[LewisRobertson-kl]

Thank you so much for uploading so many useful videos, I've been trying to generate catchments for a long time and this is the first time I've managed to get it to work! Thanks again!

Amazing tutorial, I am learning a lot from your expertise. took me a few hours to do it but finally completed all. Now I will apply this to a different catchment.
