Groundwater in Fractured Rocks
An application of X-ray computed microtomography (XCMT) for 3D measurement of fracture geometry is presented. The study demonstrates the ability of XCMT to non-invasively measure the fracture walls and aperture during the course of a reactive flow experiment. The method allows estimation of both the local and global scale dissolution kinetics of a fractured limestone sample percolated by acidic water. The measured fracture geometry was then used as an input for flow modelling, in order todoi:10.1201/9780203945650.ch43 fatcat:7ifzbkbpm5gorflcchhyxuemwq
