SWRRB Hydrolological Model & GRASS & ARC/INFO

Dear All,
   I am doing some research on integrating hydrological models
into raster based GIS. I was wandering whether any GRASS users have
had experiences with using the SWRRB model (Simulator for Water
Resources in Rural Basins) and whether any body knows of a source
from which this model and its supporting documentation may be
acquired.

   Since I last wrote to this list I have programmed TOPMODEL and
AGNPS into the cell based modelling language (map algebra) of
ARC/INFO. I may do the same with GRASS using r.mapcalc and shell
scripts in order to provide a basis for comparison. However, I think
that ARC/INFO is easier to use.

   I am actually trying to find out whether standard general purpose
GIS are any good for hydrologically oriented modelling and if so,
how best they may be applied. My ARC/INFO AGNPS and TOPMODEL
emulate the FORTRAN versions of these models quite well, but are very
slow to execute because their simulation algorithms are in command macros and
not complied.

   The ARC/INFO TOPMODEL predicts spatially distributed
saturation excess overland flow and lumped base flow, I am also
working on an infiltration excess overland flow algorithm. I have
developed spatially distributed hill slope runoff hydrographs to
predict flow entering river channel segments and incorporated a
constant velocity kinematic wave channel routing method. The ARC/INFO
AGNPS just does more or less what the FORTRAN version does.

   I would like to have ago at implementing the SWRRB model next and
also the ANSWERS model as well. If any body would like to comment on
what I have been up to, or have any similar experiences they may wish
to share with me please let me know.

Cheers,

Chris Stocks

p.s. If you know anything about the SWRRB model please pass the
information on, I also apologise to those GRASS users who don't like
hydrological modelling / ARC/INFO messages cluttering up their e_mail
list.
