: 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.

: 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.
