Identifying Backbones in Three-Dimensional Discrete Fracture Networks: A Bipartite Graph-Based Approach Open
In this paper, we present a graph-based method to identify primary flow and transport sub-networks in three-dimensional discrete fracture networks (DFNs). The structure of a DFN lends itself to the use of graphs as a coarse-scale represent…
