  How does pore liquid reconfigure within shear bands in wet granular media?
Conventional wisdom predicts that liquid is drawn into dilating granular media.
We, however, find a depletion of liquid in shear bands despite increased
porosity due to dilatancy. This apparent paradox is resolved by a microscale
model for liquid transport at low liquid contents induced by rupture and
reconfiguration of individual liquid bridges. Measured liquid content profiles
show macroscopic depletion bands similar to results of numerical simulations.
We derive a modified diffusion description for rupture-induced liquid
migration.
