Glad to hear it!

This is really well explained and useful, thank you for posting.

Fantastic! Really well explained, thank you.

Thank you for sharing! This tutorial was super helpful.

Thank you so much for sharing this. So helpful. You are a great guide through all this.

That is a great video. Thank you. Narration is simplified and clear.

Very nice explanation! Good work.

this is next level of what I studied, good thing ,this session starts exactly where my studies ends, btw..this is like a whole semester of lessons, clearly explained in 20 mins, unbelievable

This was a great instructional video - thank you!

Awesome tutorial! I was struggling with attempting to do this on my own for so long. Done in 20 minutes....

Extremely helpful! Thank you.

Thank you! so informative and execellent walk-through. leaned a lot!

Thanks, it's a great tutorial!

This was extremely helpful, thank you so much. Also, 'let it rip', indeed. I say 'giver'a'go' and I think I like let it rip much better.

Well done tutorial!

very good tutorial!

amazing! many many thanks!

Clutch Brother!

thanks a lot, it was very useful for me :)

Unbelievable.. awesome..great..

Awesome 👏

Thank you for this video! Any plans on creating a detailed video explaining the workflow of using groundwater tools?

thank you verry match its so usuful for us

awesome.

Thanks a lot! This was very helpful in understanding the entire hydrology workflow in ArcGIS Pro. Being not from hydrology background, what does the watershed polygons (or areas delineated as watershed) represent? What information does it convey?

It represents where the rain water would flow over a given landscape. Cheers

Legend thanks! I'm gonna start saying "Let's rip that" instead of "Run this bitch" from now on

You need to set the "distance" parameter in the "snap pour point"-tool to something above 0 for the tool to have any effect. Otherwise you are saying that you should look for a higher accumulation within 0 meters from the point, which will always give the same point as you have already made.

True if you are not precise with the vector point that you make. I zoom way in and place it right on the accumulation pixel. The snap to pour point creates a raster with a pixel that matches the accumulation pixel exactly. This operation is done after the accumulation tool, so has no effect on it. It is for calculating the watersheds. Cheers.

Your video has been endlessly useful! Thank you! What's your resolution? I have a dem that's 0.7m res and I'm trying to figure out what's the best raster number to put in the raster calculator for the stream network. I want to make sure I'm capturing 1st order streams, but don't want to go so far as to include any areas of flow that aren't actually flowing. Right now, the layer I've created is using 30000 as the condition.

Hi Ma'am, how do you quantify the condition that you should use based on the resolution of your DEM? I just wanna capture even the small flowing rivers...

@@heyzel302 Were you replying to me or the creator of the video? It seems like you're asking the same question as me! I have a general understanding of the major streams flowing into the lake that I'm working with so I'm able to justify the largest stream orders but not the smallest. I'm still having a hard time knowing where to stop to get just 1st and 2nd order streams because the resolution of my DEM is high enough to create flow paths where streams, even intermittent, don't actually exist. Its also includes urban areas so stormwater flow paths are also incorporated and cause trouble.

First off, thank you for the very helpful video. When going through these steps with my DEM, my final stream network results in a lot of straight lines that do not follow the topography of the land. Could this be a result of the coarseness of my DEM, which I believe is at a 15m interval contour? Or should I experiment with some of the parameters in the GeoProcessing tools?

The data link is below the description. It's a zipped gdb with one DEM in it. Cheers

Thank you so much for this tutorial. Could you share again the data for this tutorial? I couldn't open the sources🙄

Great tutorial. I have a question. When I snap pour point, I had to move the point several times to get it to snap where it should have been. Is this normal, or where am I messing up? I zoomed way in to make sure I was on the correct pixel, but it kept placing it into an adjacent pixel. I have 8 points if that is relevant.

I also was wondering the same thing and have this same exact problem

@MapPractical

I haven't had that problem when I zoom way in and place the vector point. Try using the distance setting in the tool.

I keep getting a blank view on my map when I run the flow accumulation spatial analyst tool. Everything looks good until I run that tool.. I don’t get to see the water courses even when I zoom in. Help

My mind just can't understand the flow direction, I think it is the other way around!

Since the clipped DEM does not include all the area for both watersheds, will the areas calculated be inaccurate?

@MapPractical

Yes, the tools will only calculate watersheds within the extent of the DEM.

I don't know if anything has changed since this video posted, but I am having issues with the last raster calculator, I have Con("FlowAccummulation", > 1000, 1) just like the video, but am getting a python syntax error. (ArcGIS Pro 2.9)

It may be the version of Python. Try to build the statement from scratch with the prewritten statements.
