Hydrological Analysis Tutorial using ArcGIS Pro

In this tutorial, you will learn how to perform hydrological analysis using ArcGIS Pro, which consist of delineating watersheds, sub-catchments, river networks and calculating the corresponding geometrical properties like areas and lengths.
The only input dataset we are using for this task is a digital elevation model (DEM), which you could freely download from USGS EarthExplorer.

Thank you very much Sir your tutorials are always my first choice.

You are welcome!

Hi! I am new in this field. I need TIN data from DEM data for my physical-based model as an input. At which stage should I convert my basin to TIN, or should it be the first step before starting this? If someone can direct me, I would be so happy.

What Amazing Video 📸 Watching 👀 Sooo Nice Sharing 👍 Excellent Job 👏Thanks For Sharing

[@yangyang6008]

Thank you for the great tutorial. Could you please share the DEM?

[@muhammadzeeshan8843]

Best from the Best.
Having research aspect can you dive deep into insights in your upcoming tutorials.
To gain patterns relations and predictions

Impressive

Thanks

Fantastic teaching! Thank you MUCH!
A few follow-up questions for all who might know:
1. How to figure out direction flow of rivers - to produce a map with arrow flow directions?
2. How to decide where to place pour points?
3. For mapping Ireland, for example, ITM is recommended by my prof. However, my DEM is WGS 1984. Is it best to change the raster projection in the beginning? Or after delineation?

Brother I request that can u teach us softwares like Watergems and Sewergems, If its possible that would help water resource engineers like us. Love you 3000 brother for your all previous videos and this one tooo.

As superb as always.

[@geodeltalabs]

Thank you! Cheers!

[@kiki71196]

nice video!! I am now learning more about GIS in ArcGIS Pro, see if there are any possibilities for you to make some videos talking about network analysis haha

[@geodeltalabs]

I will, thanks for the suggestion :)

Hello Can you please share the DEM File?

[@joshuakylekjieranrosanes5478]

Hi, my geoprocessing tools were unlicensed. What can I do to make up to this? Thank you!

[@kineticfx9560]

Wonderful sir. Please tell me what esri package will work for this work flow

Thank you so much for the video. Hi everyone! I am new to this. I need TIN data from DEM data for my physical-based model as an input. At which stage should I convert my basin to TIN, or should it be the first step before starting this? If someone can direct me, I would be so happy.

A regular DEM (which is in a format like geotiff) can be converted into a TIN without having to do any of the stapes related to hydrological analysis. In the panel which is used to search for various tools, you can search for the tool "Raster to TIN", and provide your regular DEM as the input. That should output the TIN model.

[@ekinhuner2594]

@@geodeltalabs and after that should I countinue to do these steps?

[@geodeltalabs]

If you want to just create a TIN for the purposes you mentioned, then that's it. This tutorial is about deriving water catchments and river networks, and a TIN raster is not necessary for that.
