Hi Nicolas and Jonathan,
and not to forget Whitebox as extra hydrological software the results of
which may be imported:

Hi Nicolas,
If you don't get a reply here that solves your issue it may be worth
asking on the GRASS mailing list. I know GRASS has a lot of
hydrographic tools and it's integrated into QGIS so...

Hi,
I know it can't be that simple but I would like to model a river
flood in a mountainous area. I am looking for something like the
Saga Lake flood module with a LiDAR derived DEM, a seed but with the
possibility to add X amount of water. It's basically a lake and dam
scenario and you just add water and figure out where the water goes
down the valley when it goes over the dam. Of course I can't use the
normal lake flood modules because rivers are not flat therefore I
need something that takes the downhill valley shape into
consideration. Also, I am not looking for a simple channel network
map with lines and points. I would like the actual polygon or raster
representation of the 2D shape of the river channel. Can you please
point me in the right direction.
Nicolas
