Short summary
The flow of water through fractured aquifers can be simulated with computer software. For a single fracture, a map of the empty space (aperture) between the two faces is required. Traditionally, this is fed to the software by sampling the frequency distribution or upscaling. This study analyses a greywacke's fracture roughness spatial continuity (how points are correlated in direction and distance) and creates an upscaled aperture map for computer simulations that better represents reality.
