A detailed hydrogeological investigation is combined with electrical resistivity imaging using the Schlumberger depth sounding method in Garaat Sened, west-central Tunisia, to elucidate the hydrogeology and the hydrodynamics of this area with emphasis on their main controlling factors. Two types of aquifers with good reservoir qualities have been highlighted; however, their natural recharge is remarkably limited since the study area is characterized by semi-arid climate with an irregular rainfall ranging between 124 and 222 mm/y. The Mio-Plio-Quaternary siliciclastic constitutes an unconfined aquifer that outcrops along an area of ~ 125 km²; however, two other deep aquifers are enclosed within two fractured Upper Cretaceous carbonated formations in age (Abiod and Gattar). The excessive abstraction to satisfy the harmful agricultural practices and the domestic demands engender a critical balance between demand and natural renewable resources of these aquifers. This situation requires an emergency plan of management and rigorous policies to oppose the risk to groundwater availability.

在突尼斯中西部的Garaat Sened，使用斯伦贝谢深度测深法将详细的水文地质调查与电阻率成像相结合，以阐明该地区的水文地质和水动力特性，重点是其主要控制因素。强调了两种具有良好储层质量的含水层；但是，由于研究区域的特征是半干旱气候，且不规则降雨的范围在124至222 mm / y之间，因此它们的自然补给非常有限。Mio-Plio-第四纪硅质碎屑岩构成了一个无边际含水层，沿着约125 km ²的面积露头; 然而，在年龄上两个断裂的上白垩统碳酸盐岩地层中也埋藏了另外两个深层含水层（Abiod和Gattar）。为满足有害的农业作法和国内需求而进行的过度提取，使这些含水层的需求与自然可再生资源之间达到了关键的平衡。这种情况需要制定应急管理计划和严格的政策，以应对地下水供应的风险。
