Water demands from agriculture and industry have intensified groundwater extraction, prompting a focused study to bolster water resources, particularly at Gabès region (Southeastern Tunisia). Through extensive geologic geophysical investigations, the reservoir geometry structural architecture of crucial aquifers, notably Mio-Plio-Quaternary Cretaceous aquifers been studied. The integration geochemical data allows for nuanced assessment fault structures hydrodynamics. Advanced techniques, like horizontal gradient upward extension unveils features density contrasts with precision. This extends spatiotemporal analysis aquifer hydrodynamics mineralization. system exhibits four facies: Ca–Mg–SO 4 , Na–Cl–NO 3 Ca–Mg–HCO Na–K–HCO . Results reveal relative isotopic depletion, suggesting recharge under colder climates higher altitudes. However, underscores impact climate change, increasing temperature dwindling precipitation in North Africa, since mid-20th century. research is relevant contribution sustainable management by emphasizing change scenarios resources management. detailed exploration hydrogeological characteristics dynamics pivotal on effective strategies semi-arid environments.
