Hi all,

Is there a module that can be used to compute hillslope position from a DEM?

I'd like to check for associations between groundwater levels/drawdowns in
a city against this kind of landscape organization..

There is a 2015 article in which the authors used GRASS, various topo
indices and a decision tree approach to do such a classification. I'm
wondering if something more 'canned' is available..

Thanks,

Look at addon r.geomorphon, it's not exactly what you want but perhaps
could be used for your application.
