...More recently, there has been a growing interest in exploring the soil behaviour using discrete modelling approaches, in sought for key mechanisms and mitigating measures for various geotechnical hazards (see [21] for a summary)....

...This may work favourably in some cases, such as in sand production in sandstone oil reservoir, but may be an adverse factor in other occasions, such as in the case of internal/surface erosion of embankment dams and soil slopes which may trigger instability and failure of these structures [21]....

...A typical CFD–DEM method solves the Newton's equations governing the motion of the particle system by DEM and the Darcy's law or the Navier–Stokes equation for the fluid flow by CFD, in consideration of proper interaction force exchanges between the DEM and the CFD (see [21,27,32,33,37])....
