The paper provides a survey of approaches to groundwater flow modeling in fractured porous media, discussing their merits and shortcomings. The DFM (Discrete Fracture and Matrix) model implemented in the GeRa software is described, emphasizing its capacity to explicitly consider the geometry of fractures and the water exchange between fractures and the porous matrix. The use of multipoint flux approximation on the fracture within the finite volume method based on the O-scheme is proposed. The implemented numerical scheme is applied to solve a practical problem of estimating water inflow to underground research laboratory in a fractured rock massif.
Keywords: groundwater flow, fractured porous media, finite volume method, multipoint flux approximation.
