[MITgcm-support] OBCs balance and sponge

I am trying to set up a configuration with MITgcm where the basin is
semi-enclosed, with an open boundary on one side, which is split in two
portions. In the first part, velocities are precribed as inflow (where
there is a gradient in topography, so this drives a boundary current),
while the rest of the open boundary is "open". I tried using Orlanski
radiation conditions, but I keep having very high velocities just at the
limit between the OBCS prescribe area and the OBCS Orlanski area, and
the model finally blow up. I would like to try OBCS-balance and
OBCS-sponge routines, but the manual lacks details on what these
routines actually do and which parameters have to be specified.
Any help would be grately appreciated ...
