A couple of us have used the SWAN wave model (GPL, FORTRAN) with GRASS.
  http://fluidmechanics.tudelft.nl/swan/default.htm

workflow was like: 

generate DEM bathymetry in GRASS (v.surf.* and friends)
export bathymetry as ascii grid (r.out.ascii)
set up and run the model
load results into Matlab
do_stuff()
import back into GRASS with r.in.mat
do_stuff()
plot it.  (ps.map, d.rast.arrow, r.contour, thresholds, ...)
