I have a DEM I want to generate a HAND for and want to do so in QGIS. Does anyone know of any plugins or the processing steps to be able to do this?


Actually, I did not generate HAND from DEM before, but based on High Resolution Hydrography and Hydrologic Modeling PDF reference file, they use TauDEM tool accessed from ArcGIS, as you can see in Slide No. 10. TauDEM tool can be accessed from QGIS: TauDEM algorithm provider but you need to it install it separately from Utah State University and configure it manually.

Here is the TauDEM tool in QGIS.

  • Which tool is for the Height Above the Nearest Drainage (HAND) according to your image? – ilias m Apr 3 at 21:48
  • @iliasm I am not referring to the HAND tool, I am referring to the TauDEM tool in general. As I said, I did not use HAND tool before, but according to the PDF slides (I fixed the link), the author used TauDEM tools for the analysis. You can refer to the PDF for more information. – ahmadhanb Apr 4 at 1:12

I would like to give a more detailed answer to this question. You need to use the above-mentioned tool and the workflow is displayed below. enter image description here

I executed this process (without 'NHD HR Flowline' and 'NHDPlus Flowline 1:1000000' files) but the values of HAND were higher than expected.
