Hi everybody,
A new module called r.terraflow has just been submitted to CVS. It takes
as input a raster DEM and computes flow directions, flow accumulation
and a couple of other indices. r.terraflow was designed and optimized for
very large grids; it is able to process grids which are untractable with
previous functions, like r.watershed. Terraflow has been recently ported
to GRASS and not tested extensively. If you have any suggestions please
let me know.
thanks,
-Laura

The code is placed here:
