[GRASS5] hydraulic model tools

[Raymond Burns]

Hi

Somewhere between 5.3-7 and 6.0-1 , a number of hydraulic modeling
tools were left out of the CVS tree. 

Are there reasons (beyond time, workers and interest) to not overhaul
and bring back some or all of these tools ?  Are they being worked on
as part of a raster revamp ?

I have been working on r.hydro.CASC2D with some results. The patch
would be a little bit large to just throw on the mailing list and I am
wondering just what to do with it.

Thanx
  Ray
