How to use a DEM to delineate a Watershed/Basin in ArcGIS
Ғылым және технология
A watershed is the upslope area that contributes flow to a common outlet as concentrated drainage. It can be part of a larger watershed and can also contain smaller watersheds, called subbasins.
This tutorial shows step by step how to delineate a Watershed using a DEM and ArcGIS Hydrology tools.

This is the best tutorial I've ever watched.
Thanks for the awesome tips to work with DEM data. I'm thrilled.
thank you so much. rather than learning delineating, I learned how to use other tools also.
thanx sir, Can you please provide video about how to derive morphomertic parameters from that stream network.
Thank you so much for this tutorial! Saved my life for my final Graduate project for my Spatial Analysis class. I used this to delineate the Mississippi River watershed

@Misael Benton You are welcome xD
Thanks so much for this wonderful tutorial
thanks a lot however how could fix watershed area in the region of 250-500ha(how much is its pixel size) which is manageable size for watershed development.
Hi, I want to extract only watersheds of rivers with a surface equal or greater than 10 kmq... there is a metod to do this?
Your video is fantastic!
could this be the same as mapping flood hazard areas?
Thanks for explaining and this lecture was really helpfull
Thank you sir, this worked like charm
may i ask how do you choose the watershed boundary ?
Can you extract water bodies having
Hello sir am finding a problem in delimiting a drainage area and tracing and doing calculation. Can I get help please.
Very nice video
Can someone tell me what song is this on the background?
Polygon vector layer and shapefile are two different things?
YOU YES YOU . . . . The one reading this. You are beautiful, talented, amazing and simply the best at being you. Never forget that.
How do you know if you have the right basin?.
What does the numbers means in Basin>Value>high&low. Much thanks
Really helped a lot😇
Awesome bro.. Tq
Respected Sir, A kind request to you to kindly upload videos in which you narrate what all you are doing as it makes the video more interactive and unlike many other videos you have uploaded where the mouse pointer is highlighted which after a short time makes the video monotonous. Regards, Gaurav.
very good tanks alot
thant you verry much , c'est magnifique
Thank you!
Thank lot very simple and easy to understand
please make tutors how to make vegetation zone and elevation zone in arc map to prepare data for hbv model
Sir please pour point delineation
thank sir,
Why did you decide Flow Accumulation over 40,000?
thanks a lot
thanks sir
why i cant clip it?
excuse me, why can’t i click the fill in hydrology arctoolbox? its showing x sign in fill
That's Great
awesome
Hi sir Can you please guide me how to calculate volume/capacity of a water body/reservoir?

you could get the area, either using arc gis or google earth, then you will go the the reservoir physically and obtain the height of the reservoir, multiply area and height, you will get the cap[acity
thanku
I love you
How do you know which polygon to clip? lol
This music makes me want to work out with Hal Johnson and Joanne McLeod.
why did you choose 40000 for map algebra?

40,000 is the threshold value. It is represent the minimum number of cells that constitute a stream network system.
