Abstract :<\/strong><\/p>\n\n\n\n

Discrete Fracture Matrix Model (DFMM) offer clear insights into fluid exchange and mass transport\/heat transfer between the porous matrix and fracture in the vicinity of conduits.<\/p>\n\n\n\n

The applicability of DFMM to field studies with realistic assumptions (e.g. often involving large spatial and\/or temporal scales) is often limited; not only because it requires<\/p>\n\n\n\n

detailed fracture characterization, but also as it involves excessive computational efforts.<\/p>\n\n\n\n

The applicability of our method and developed tool is then demonstrated in a study concerning the effect of climate change on groundwater resources in a karst aquifer\/spring system in El Assal, Lebanon.<\/p>\n\n\n\n

Simulations, including recharge predictions under climate change scenarios, are carried out for about 80 years, up to 2099.<\/p>\n\n\n\n

This study demonstrates the applicability of our proposed scheme to deal with real field cases involving large time and space scales with highly variable recharge.<\/p>\n\n\n\n

Our results indicate that the water-table level is sensitive to the presence of fractures, where neglecting fractures leads to an overestimation of the available groundwater amount.<\/p>\n\n\n\n

Furthermore, the flexibility and versatility of the model to embrace new modules and physics are briefly discussed.  Primary insights into the potentials of the choice of the numerical schemes<\/p>\n\n\n\n

for being applied on new physics, including the electrical current in porous media and electrical resistivity evolution, are examined and have been shown to have significant potentials.<\/p>\n\n\n\n

The proposed numerical approach is generic for DFMM and can be extended to different 2D and 3D finite-element frameworks.<\/p>\n\n\n\n

Keywords<\/em><\/strong>:<\/strong> discrete fracture matrix model; electrical resistivity; method of lines; mixed hybrid finite element method; unsaturated fractured porous media.<\/p>\n\n\n\n
