Watershed Delineation in QGIS (Quickest & Easiest Tutorial)

This tutorial will describe the shortest & easiest method to delineate watershed in QGIS.
You just need a DEM (Digital Elevation Model) of desired area and a reference base map like Google map of Google Earth Images

I sincerely wish all QGIS tutorials on YouTube were this straightforward and easy lol <3 Thanks Guru.

Very concise and practical, can't believe how much I learnt within only 10 min. Thank you.

Most easiest tutorial ever seen for Watershed Delineation using QGIS,
Thanks

02:04 Fill sinks (by Fill Sinks - Wang & Liu). Make tolerance to be zero.
02:41 Get Stream order (by Strahler Order).
03:31 Extract streams above specific order (by Raster Calculator or Layer Styling Tool).
04:36 Get coordinates of interested river outlet to retrieve corresponding watershed.
05:02 Get watershed area (by Upslope area)

Excellent tutorial. I could generate the watershed polygon using this technique. Thank you Geo Guru.

After Delineation, how do I represent the Delineated area in terms of elevation, rainfall and land use?

[AbuzarGaffariAZ]

absolutely spot on, i was just looking for this, kudos to Geo Guru, really great work !!

What is the use of finding ground water areas using gis software

What is the output finally what we are going to conclude

[majesticchicken]

i can’t find the reprojection option under the raster. and when I’m searching for it, its also not showing up. please help!

[sayansantra]

hello, fantastic job on making this concise and precise video. But i'm stuck with upslope area as error is popping up "tool needs graphical user interface [Upslope Area]"....what to do?

SAGA version 7.8.2 is not officially supported - algorithms may encounter issues. IM USING 3.26. can u help me>

[remimayou]

Thank you very much Geo Guru, this tutorial is very helpul ! Right now, I'm looking for explanations about the different operations (Fill Sink, Strahler Order, ...) and how they work and produce a result. If you have references, do you mind sharing them ?

[aloisiojbc]

Hi, great video. Please could explain the use of GRASS tools (r.lake; r.volume and r.surf.area)

[communistinternational]

We can do the lat long part by creating a point shp file also right?

[udigiripraveen]

In the last step It is showing that the layers were not generated correctly and upslope area layer is not created.. how to solve this issue sir.

[rafiaanjumrimi]

when I am doing reprojection, "the following layers are not correctly generated" is showing. how can I solve the problem

[TonyGokuSS]

Very compliments for this video. It is really a simple and performing solution. However, is there a method to pass a shp with multiple points to the upslope function and retrieve a polygon for each of them? Thanks.

[shubhambathwal]

From where can i download dem file for the same area ( parbati )
Could you please forward the dem file to me?

[shermanfrancis]

Great video. Thanks so much for sharing.

Interesting tutorial, also if I'm not able to obtain any valid result from 'Upslope area' tool.
