Hello i was wondering i anyone here is experienced in geomorphometry?

I have a DEM dataset of an area of landscape that is heavily eroded with gully features.

What I would like to try to automatically map these features. So for example a polygon layer would be created showing where these features are.

Other things I would like to try include calculating the area of gullying compared to the rest of the DEM.

Also if there was someway to calculate the total volume of surface material lost to gullying that would be amazing
