Thank you so much for clearing it up, i've been banging my head against a wall because of an exercise about a watershed - read both the term in lectures and the wiki articles without success, but you saved me so much time!
I strongly recommend working from the pour point (or outlet) upslope to ridges on both sides of the stream valley first, to be sure your watershed boundaries stay perpendicular to the contours. The boundary drawn at the very end of this delineation is incorrect (it is not perpendicular to the contours), which is easy to avoid when this method is performed in the right order. I strongly disagree with the statement that "there is no way to do this correctly". Perhaps you mean, "there is no SINGLE way to do this correctly for a given watershed"? That is true in some sense when connecting ridges, but there are are parts of this process will reduce the chances of a mistake if performed in the proper order.
This was helpful, thanks! do u have any videos on how to draw subwatershed? I kinda know how to draw one big watershed but im not sure where to divide them. My streams look similar to the one in this video; two 1st order streams and one 2nd order
This gets you close, however the watershed should start from the outlet and work your way up on each side, and simply follow the contours at perpendicular angles until the ridges meet. This would be the "right" way. There is no guess work this way. Where you turn your watershed in toward the outlet, you actually overshot the watershed. This wouldn't occur if you follow the perpendicular rule. You can do this in the field as well, walking the boundary of the watershed, starting from the outlet and mapping each side until they converge.
Hello sir I have one assignment of delineating watershed boundaries but since I am new learner I am confused how to make it. I was wondering if you could help me out?

So so helpful🙌🏼
Wasnt able to undrstand from books but u made it easy
Seems very easy when you explain it. Thanks a lot
Awesome buddy, very clear and eloquent
Great video, I was totally lost on an assignment but this put me on the right track :D
Thanks a lot for this! Totally helped me.

Why is the ridge that is circled in red in the top right is not used at all in the delineation?

Thank you Lecture Simmy Sigma really it's helpfull.
A real life saver
Thanks a lot. really really really helpful 😘
This was very helpful
Very helpful. Thank you very much
What I just saw was really helpful. But i have one doubt. What you mean by this outlet? Is that the way through these collected water taken out?
I think its just the lowest point where water will possibly get out from
Very nice work ..
Thank you so much!!
Hello sir
I have one assignment of delineating watershed boundaries but since I am new learner I am confused how to make it. I was wondering if you could help me out?
The black outline in the video are precisely (from what i understood) the delineating watershed boundary
hi can you plz tell me which software you are using in this video? Thanks
Thank you
how export this watershed to wms and determine morophgical characteristics
"There's no way right way to do it, but there are a million wrong ways to draw them" 😭
Thanks
thank you!
Very good video but next time see if you could use a brighter or more distinct cursor as it hard to follow
perpendicularly is indeed a word
It's easy when you can actually see something on your map. Mine looks like a one, big, fucking mess... Even with magnifying glass...
Tnx

Txuuuu
Dude, you fucked it up at the end. Go perpendicularly up from the study point first to find the ridge. This basin isn't even right.
