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!

[@043_kirtibarnwal3]

So so helpful🙌🏼 Wasnt able to undrstand from books but u made it easy

[@MrBmike98]

Seems very easy when you explain it. Thanks a lot

[@chorgulio]

Awesome buddy, very clear and eloquent

[@mastermavrick1818]

Great video, I was totally lost on an assignment but this put me on the right track :D

[@nashydrew8596]

Thanks a lot for this! Totally helped me.

[@rm4470]

Very helpful. Thank you very much

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.

Very Helpful🥰

A real life saver

[@ryanmcgowan3061]

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.

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

[@mohammadmurie]

Thank you

[@DeagleBeagle]

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

[@samirtaher2998]

how export this watershed to wms and determine morophgical characteristics

[@boubbaker8407]

Thanks

[@asmaakhter1953]

hi can you plz tell me which software you are using in this video? Thanks

[@iradhossain3455]

Tnx

[@annuvtt1]

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?

[@santrammeena3]

I think its just the lowest point where water will possibly get out from

[@magslife8101]

Very good video but next time see if you could use a brighter or more distinct cursor as it hard to follow

[@pateljigar7118]

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?

[@galaxydeathskrill5607]

The black outline in the video are precisely (from what i understood) the delineating watershed boundary

[@jessejames1520]

perpendicularly is indeed a word

[@adriantoadrian4302]

Txuuuu

[@TheMiseriaCantare]

It's easy when you can actually see something on your map. Mine looks like a one, big, fucking mess... Even with magnifying glass...

[@luvuyomsizi3072]

"There's no way right way to do it, but there are a million wrong ways to draw them" 😭

[@bjcampbell5600]

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.
