Watershed Delineation Using ArcGIS 10.3

[@himashwitharana3263]

When using the raster calculator why did you select "accum>500"? What is the 500 value? What does it depend on? Thank you!

[@sandeepdhone8669]

Thanks sir, your video is easy to understand.... I am having problem as follows. Selected polygon on google earth to download DEM for watershed delineation. But after delineation streams are not there at exact same place of selected polygon on google earth.

[@TerraSpatial]

Hello Sandeep Dhone, 1st solution please change your projection based on study area. 2nd solution try to select the data in earth explorer rather than google earth. Thanks for your valuable question.

Nice job. This was quite informative.thanks.

[@TerraSpatial]

Thanks

[@dorji83]

how to classify watershed area into different categories such as degraded, normal and pristine. Thank you.

[@hasibartiq7623]

could you please describe why did you put 500 in raster calculator section? I mean what does it shows ?number of streams or something else?

[@TerraSpatial]

Hello Mr. Hasib, it is the standard value in low accumulation and helps in showing the stream. Thanks for your comment.

Hello Sayedul Kibria, thanks for your valuable comment.

[@Francisramil]

What is the standard value in low accomulation. It is necessarily > 500?

[@TerraSpatial]

Yes, Mr.Neil

[@Gitau_Kenn]

After delineation, can I clip the watershed with the dem feature only?

[@TerraSpatial]

Hello Mr. Kenn, Yes you can clip the watershed with the DEM Feature. Thanks for Question, If any doubt please contact me.

Good video. Thumbs up still, but you should turn up your microphone a lot.

[@TerraSpatial]

Hello Mr. Brain Fairchild, Thanks for your valuable comments and suggestion. I will improve the quality of the microphone soon, thank you.

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?

[@TerraSpatial]

Hello Mr.Gaetano Patti, Yes it is possible. From the above video please watch till creation of basin, you will get the idea.

[@gaetanopatti7648]

Thanks for the reply but when you create the basins you can't choose the size of the watersheds

[@TerraSpatial]

@@gaetanopatti7648, I don,t think so, we can't choose the size of the watershed, i will do some research and let you known if any possibilities are there. Thanks for your question.

[@satyakidas572]

Hey ...how can i differentiate the vegetation areas using arcmap

[@sandyk7371]

Thanks.... And how get water volume catchment area

[@TerraSpatial]

Hello Mr. Sandeep Lohra, thanks for your valuable comment. Using ArcSWAT can help you in providing you with water volume of the catchment area. ArcSWAT is extension, please try it.
