Abstract Monitoring the hydraulic properties within subsurface fractures is vitally important in contexts of geoengineering developments and seismicity. Geophysical observations are promising tools for remote determination properties; however, quantitative interpretations hampered by paucity relevant geophysical data fractured rock masses. This study explores simultaneous changes natural with i...

Fractures commonly exist in rock masses; the coalescence of fractures provides fluid flow pathways a fractured mass and greatly increases capacity rock. This work aims to study characteristics nonlinear fractures. A series tests were conducted indicated that Forchheimer law performed well when describing relationship between hydraulic gradient flow. The test results also indicate higher water p...

The seismoelectric logging method is based on measuring the electric field generated by seismic waves in a fluid-filled borehole. Two kinds of electromagnetic (EM) fields can be generated within the formation and at the interface of formations. One is a stationary or local EM wave and the other is a radiating EM wave. In this paper, we make various fractured borehole models with artificial mate...

One of the current objectives of karst research is to understand the spatial dynamics of karstic processes that increase or decrease pore volume. Although we can construct 3D numerical models, it is a complex, multi-step process. These modelling approaches combine a dissolution algorithm, a flow and/or transport model and an algorithm to reconstruct the spatial geometry of fracture networks. Th...

Using the lattice Boltzmann method, we study fluid flow in a two-dimensional (2D) model of fracture network of rock. Each fracture in a square network is represented by a 2D channel with rough, self-affine internal surfaces. Various parameters of the model, such as the connectivity and the apertures of the fractures, the roughness profile of their surface, as well as the Reynolds number for flo...

Fractures are common traumatic injuries that mainly occur in the metaphyses of long bones such as the proximal humerus, distal radius, and proximal femur. However, most studies of fracture repair processes have focused on the diaphyseal region. In this study, we compared the bone repair processes of the metaphysis and the diaphysis of the mouse tibia. Bone apertures were formed in the tibial me...
