Kapo,

   r.topmodel, r.sim.sediment, and r.sim.water are hydrologic models. That
is, they model water flow over the terrain and (with the later two) identify
erosional and depositional areas for sediment transport. I know that often
'hydrology' refers to all water flow, but I'm used to distinguishing between
surface flows (hydrology) and in-channel flows (hydraulics).

   What I would like to acquire are tools similar to those of the National
Center for Computational Hydrodyamics and Engineering (NCCHE) at the Univ.
of Mississippi (USA). Unfortunately (from my perspective) their software
runs only under Microsoft and requires ARC/Info v.2 or 3. I run only linux
and want to integrate in-channel flows (flooding, morphometric changes) with
GRASS.

Thanks,

Rich
