The properties of individual fractures in rock including spatial position, trace length (size), aperture, surface roughness are well known to be scale independent, an important input into synthetic models of fracture networks. Fluid flow paths through fracture networks have been modeled using percolation theory which also exhibits scale independence in the network and flow pathways. One of the holy grails of fractured rock hydrology has been to develop a high-resolution geophysical method for imaging fluid flow through fractured rock in the field in real time. There have been recent advances using tomography and other methods. Significant implications extend to oil and gas flow induced by fracking, groundwater movement, and the movement of contamination plumes. This session invites papers on imaging and modeling the physical and flow properties of individual fractures and networks of fractures and their scaling properties
