To provide a better understanding of the variation of hydraulic and geometrical characteristics of a fracture subjected to shearing, coupled shear ﬂow tests on the fracture for four shearing displacement steps under constant normal stress were performed. At the end of each shearing step, computed tomography (CT) scans with resolution 26.8 μm were obtained and the corresponding fracture geometries were evaluated. The CT images were used to generate full aperture maps of the fracture conﬁguration. In addition, average aperture maps were also created by averaging the full-resolution data over 10 × 10 pixels, smoothing out ﬁne structural details. Computational modeling of water ﬂow through the fractures at different shearing steps was performed using a modiﬁed local cubic
