This study presents a comprehensive framework for reevaluating the suitability of an old active dumpsite and identifying potential sites in the Abhar region, Iran, through geophysical tomography survey, hydrogeological investigation, and the GIS-based AHP method. The results of 2D geoelectrical tomography demonstrated that the leachate plume, with a concentration depth of ~ 20 m, has not affected the aquifer, which is at the minimum depth of 70 m. Our interpretation of the permeability measurement through Philip’s equation reveals that the dumpsite topsoil has a low to middle permeability, ranging from 3 to 5 mm/h. After field investigations, three main criteria and twelve sub-criteria were selected and weighted by the AHP method. Accordingly, a ranked suitability map was prepared using a weighted linear combination method in GIS. The suitability map confirms the dumpsite is situated in a moderately suitable class. The most suitable, suitable, moderately suitable, poorly suitable, and least suitable zones cover 4.87%, 20.14%, 34.25%, 37.21%, and 3.72% of the Abhar plain, respectively. We have also defined vacant lands in the eastern and southern parts of the dumpsite for future operations. The method applied in this paper can be used for the suitability evaluation of other underground storage facilities.

重新评估旧的活动垃圾场的适用性的多方法方法：在伊朗阿卜哈尔平原的应用

这项研究提供了一个综合框架，可通过地球物理层析成像调查，水文地质调查和基于GIS的AHP方法，重新评估旧的活跃垃圾场的适宜性并确定伊朗阿卜哈尔地区的潜在地点。二维地电层析成像的结果表明，浓度约为20 m的渗滤液羽流并未影响最小深度为70 m的含水层。我们通过Philip方程对渗透率测量的解释表明，垃圾场表层土壤的渗透率较低至中等，范围为3至5 mm / h。经过现场调查，选择了三个主要标准和十二个子标准并通过AHP方法加权。因此，使用加权线性组合方法在GIS中准备了排序的适合性图。适宜性图确认垃圾场位于中等合适的等级。最合适，最合适，最合适，最差和最不适合的区域分别覆盖了Abhar平原的4.87％，20.14％，34.25％，37.21％和3.72％。我们还定义了垃圾场东部和南部的空地，以备将来使用。本文所采用的方法可用于其他地下存储设施的适宜性评估。
