  We show how liquid migrates in sheared unsaturated granular media using a
grain scale model for capillary bridges. Liquid is redistributed to neighboring
contacts after rupture of individual capillary bridges leading to
redistribution of liquid on large scales. The liquid profile evolution
coincides with a recently developed continuum description for liquid migration
in shear bands. The velocity profiles which are linked to the migration of
liquid as well as the density profiles of wet and dry granular media are
studied.
