My Strahler and channel data shows unreastially very high number streams. Adjustment in field values before the operation doesnt seem to work properly either
Thank you for your videos. I am looking to devide the catchment (like in the video) in several subcatchment. For example in arcmap we could insert several pourpoints and after that we can create the subcatchments. In qgis there is any possibility to derive the subchatment from the catchment?
Hello.. Thank you for the video.Iit is so useful.I have a questions regarding of delineating the catchtment. Inside the catchment i want to derive several subcatchments. Is it possible? For example in arcmap we can insert several pourpoints and after that we can delineate the subcatchment for those pourpoints. I want to do it in qgis but i cant figure out how to do. I tried to add a shape file With multipoints and adding the pourpoints in the strahler order and use the upslope area but it requires the coordinates for only one point. Also tried to run as a batch process, where i added the coordinates, but is doesnt worked. Please can you help me how to operate? Thank you!
Have you launched Grass also? Do not use the WGS coordinate system. Try with QGIS 3.15.5 and Grass 7.8.5. Feel free to comment if you still face the problem. We are happy to help.
Depends upon the unit you have set. You can check the unit system your QGIS is running. In default, generally we have meters as unit. Hope this works. Thanks
ruclips.net/video/DamLMz2icPY/видео.html please follow this link. Here you can easily change the unit to your preferred one. Hope this will help you. Happy learning!
great tutorial. I use QGIS 3.24 and Saga Next Gen 7.8.2 and got the same error like you in 7:07 SAGA Version: 7.8.2 (64 bit)
Error: tool needs graphical user interface [Upslope Area] And Loading resulting layers The following layers were not correctly generated. Despite your layers were created. mine werent 😅
I have encountered same issue and came to conclusion that there is a bug which is not yet solved (something with python plugin and qgis and python version) please use versions 3.16, 3.10 or earlier and it would work like charm
Hello Erick, our apologies if there are any inconveniences. Would you further elaborate the situation here! Your valuable comments means a lot to us to improve the channel in every possible way.
Holy - this actually worked! Thanks, I had been struggling for a long time, great video
Thats very simple and easy to learn along with being detailed and informative
Thankyou for such efforts 🙏
Excelente metodología, no conocía estas herramientas, hacen el trabajo mucho más ágil y rápido.
Muy buen tutorial, agradecimientos.
I don't have saga in processing toolbox...pls help 😢 how to get
Hi, may I ask why SAGA is not showing even if I already installed it in my plugins?
My Strahler and channel data shows unreastially very high number streams. Adjustment in field values before the operation doesnt seem to work properly either
My Filled DEM does not seem to be working. I get the message that the layers were not correctly generated.
Very nice presentation 🎉

great video.
sir ,
is there any automated method to do this like any python programm which can do it in live time
Thank you for making this video! Very helpful! :)

Hey, i have the same problem here. Did you find any solution?
Upslope area tool isn't working for me, give error: Error: tool needs graphical user interface [Upslope Area]
Please help!

@@qgisworld1922which coordinate system should i use then
Qgis version?
wheres the link for the dem??
Great tutorial. Thank you !

thanks, clear and useful
Why is mine doesn't have any SAGA in my processing toolbox? Kindly help, thank you!
Which version of QGIS you are using?
@@qgisworld1922 I used QGIS 3.32.0
PS. Thank you for the fast reply 🤧
Thank you for the video.
But I don't have the SAGA module? How can I have it???
download from plugin
this tutorial is the dream
Thank you so much Fabi. Don't hesitate to email us for any assistance related to QGIS.
Happy learning ☺️

Thank you sir. But i want to the area in m2 or hectar? Tell me how?
Depends upon the unit you have set. You can check the unit system your QGIS is running. In default, generally we have meters as unit. Hope this works. Thanks
where is the DEM link ?
thank you very much. However, can you share how to calculalate total watershed area in QGIS
You can just calculate the area of the watershed polygon. You can view another video in this channel which calculates the area of the polygon.
How to get DEM of the watershed or river ?
You can download DEM for free. Please checkout the another video in this channel related to downloading the DEM.
Why cant i generate upslope area what is the problem
The coordinate system should be projected one. Not WGS
Is it possible to create subwatersheds in qgis by adopting the same method?
Yes, just change the location of a pourpoint to a smaller watershed or sub-watershed.
No fil and silk in Qgis 3.28
Please follow the previous comments.

Where is the link for DEM file.
yep also looking for it!!
Good video
جزاك الله خيراً
Thanks!
upslop is not formed
Same here
Which coordinate system you are using?
thanks
so whats the area?

@@qgisworld1922 i followed every single steps in the vid. but mine is not working. even the log report is the same.

Please use projected UTM coordinate system.
