“…For elaborating the groundwater flow model, the primary purpose is how to describe the heterogeneity associated with fractures of the Sarhlef schists aquifer. Modeling processes in hard rocks and their associated fractured aquifers has been of high importance last decades [8,16,19,28,29,35,39,52,61]. One of the simplest approaches is basing on the concept of a representative elementary volume.…”

In this study, we present the efficiency of remediation scenario to attenuate the impact of acid mine drainage (AMD) contamination in the Kettara abandoned mine site. The study focuses on the AMD groundwater contamination of the Sarhlef shists aquifer. To predict the evolution of AMD groundwater contamination in the Kettara mine site under remediation scenario, a model of groundwater flow and AMD transport was performed.Piezometric heads were measured at the dry and wet periods from eleven wells located downstream of mine wastes. To elaborate a conceptual groundwater flow model, we faced with to the heterogeneity and anisotropy of fractured Sarhlef shists aquifer. Consequently, the study focused on the use of various approaches: 1. The inverse modeling by the CMA-ES algorithm is adopted as an alternative approach to determine hydraulic parameters indirectly, and 2. the model is treated as an equivalent porous media (EPM). The groundwater flow model was carried out in steady-state and transient conditions in the dry and wet periods using the PMWIN interface. The obtained results are satisfactory and show an excellent correlation between measured and computed heads. Contaminant transport model is used to solve the advection–dispersion equation and to generate the AMD concentration by MT3D via the PMWIN interface. A sensitivity analysis of the dispersivity coefficient is carried out. The AMD transport simulation was computed during periods of 1, 5 and 10 years, and the performed model indicates that the simulated concentrations under remediation scenario are reduced 1000 times comparing to the current concentrations. The study revealed a necessary approach in addressing an environmental issue for the AMD contamination. The results of the study will be a start-up for further research work in the study area and implementing it for the prevention of AMD propagation plume.

“…One prominent example in Iraq is Bahr Al-Najaf depression that suffers from many shortages in surface water quantities in spite of the seasonal income of surface waters by means of the existing ephemeral wadies. This is because of its geographic location (near the Southern Desert), away from surface water resources (Thabit et al, 2018), groundwater such as the artesian, self-flowing wells and the springs are the major water sources for domestic, industrial and agricultural uses in this area (Al-Shemmari, 2012).…”
