    "abstract": "The effect on the transport properties of fractures of a relative shear\ndisplacement $\\vec u$ of rough walls with complementary self-affine surfaces\nhas been studied experimentally and numerically. The shear displacement $\\vec\nu$ induces an anisotropy of the aperture field with a correlation length\nscaling as $u$ and significantly larger in the direction perpendicular to $\\vec\nu$. This reflects the appearance of long range channels perpendicular to $\\vec\nu$ resulting in a higher effective permeability for flow in the direction\nperpendicular to the shear. Miscible displacements fronts in such fractures are\nobserved experimentally to display a self affine geometry of characteristic\nexponent directly related to that of the rough wall surfaces. A simple model\nbased on the channelization of the aperture field allows to reproduces the\nfront geometry when the mean flow is parallel to the channels created by the\nshear displacement.",
