![]() ![]() Promising flow and head results are observed for fine and coarse grid models. A porosity estimation is proposed to identify the grid-pressure transient response. ![]() ![]() A grid-conductivity correction is needed to preserve the DFN flow in the presence of wells. Flow and head discrepancies between the proposed technique and the DFN approach (reference solution) are assessed in steady and transient conditions. The grid flow problem is solved via MODFLOW. Fracture segments are mapped onto grids of 1 × 1 m and 5 × 5 m resolution as conductivity and specific storage cells. The DFN flow system is solved by applying the mass balance equation at fracture intersections. A stochastic generation of the DFN is performed in a Monte Carlo framework taking into account wells positioning. The main objective of this research is to develop a computationally efficient technique based on the FC approach to simulate the radial groundwater flow towards wells through two-dimensional fractured media under both steady and transient conditions. The fracture continuum (FC) approach arises as an integrated technique that incorporates the merits of both approaches. The SC approach ensures fast processing but results in system over-homogenization. Although the DFN approach is the most accurate, it has computational and memory constraints. Two modeling approaches are commonly utilized for simulating flow in fractured formations: the discrete fracture network (DFN) approach and the stochastic continuum (SC) approach. ![]()
