Hello. I found this old discussion very interesting http://osgeo-org.1560.x6.nabble.com/Re-GRASSLIST-7895-Re-Hutchinson-s-Adaptive-Alogrithm-for-sound-DEMs-tt4030188.html#none and I realized that it is quite complex. Looking in various modules I realized that maybe I could use r.watershed, and maybe I could use a raster a flow model based in vect line and still use bocking input with tree Well I'm undecided I have a lot of work to do now, and within a week I wanted to submit a report to the farm (the consultancy is funded by the rural development plan of my region, and I could look great!) winter, when I have more time to devote to it. Thanks a lot anyway!
