[GRASS-user] r.carve default value (design keyline simulation of water drainage)

[Enrico Gabrielli bonushenricus]

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!
