Dear colleagues,
I am currently working on automatic/semi-automatic delineation of alluvial fans using remotely sensed imagery. Based on your own experience, could you share an active Arcgis tools or add-ins and briefly explain why you give the preference to this tool/add-in.
Sincerely,
Hi Mariam Tsitsagi
I think for automatic/semi-automatic delineation of alluvial fans, the tools that you use should be capable of processing the elevation-derived products to determine fan-shaped elevation lines at the mouths of tributaries and be able to process soils maps for soils designated as “local alluvium.” It also partially needs to consider the wind speed and direction as well.
When using remote sensing imagery such as Landsat, you need to check for reliable spatial interpolation and aligning as well due to different resolutions and projections of elevation and other imagery. You may use the new and free tools in QGIS. See the following articles:

I also attached an older article on the topic.
Hope they are helpful!
Best regards,
Ebrahim
