Nice! Some steps seems too complicated, I suggest using r.null for some of
the steps. I think the problem is the break raster. It should have 0
everywhere except for the part of dam which breaks, that part should have
the height of the dam break, for example tens of meters. r.damflood
computes internally the new DEM as DEM with the dam minus the break raster.
I hope it's clearer now.
