Hi, I was wondering if there is an automated approach and/or more guidelines* for delineating Pfafstetter basins with GRASS?
I'm using r.stream.order and r.stream.basins modules (as described in Jasiewicz & Metz (2011)), but uncertain as to the best approach to delineate Pfafstetter basins. Using r.stream.extract, I've output stream_rast, stream_vect and direction layers. Using r.stream.order, output a layer with Strahler's stream order However, what is the best approach to output Pfafstetter basin topology using r.stream.basins/r.reclass? The challenge it seems is to generate data on tributary accumulations for ordering of the Pfafstetter basins ... ?
