The QGIS version that I'm using in this tutorial is QGIS 3.34 Prizren (LTR), In case if you want to make sure you have the same version installed at your end to potentially not have any version conflicts.

Thanks Sir for your content! I follow you since 4 years. I meet issues using Saga tools in qgis. all Saga algorithms used to derive river networks and catchment delineation don't work in all QGIS version. Could you please help fix that issue?

When it is required to use Projected Co-ordinate system and UTM zones are unknowm, just use EPSG:3857. it is pseudo-mercator projection. It is similar to UTM projection. EPSG:3857 has unit meters.

Thank you for this very informative video. Do you, by any chance, know how to extract the lineament density of a catchment from a 1m DEM? It would be useful to have a tutorial on this topic. Thank you!

Awesome tutorial dude! I have a doubt, save the raster with the "Save as" have the same effect as the Warp(reproject)?

Thank you for this helpful tutorial. Could I ask for your assistance with an error message I encountered while processing the channel network and drainage basin: 'The following layers were not correctly generated.' Your help would be greatly appreciated.

A potential fix for this that may work is making sure you are running one of the recent versions of QGIS (such as QGIS 3.34 LTR - Prizren, which is what I happen to use currently), and then install SAGA Next Gen Provider plugin on that. You might be able to circumvent the version issues that way.

I proceeded all along, but has not got any stream network, just random pixels. Also the suggested approach seems not to work if one has to delineate the catchment area of the reservoir and the river dale is wide.
