ABSTRACT Due to complex hydrogeological contexts, mapping groundwater potential zones in karst regions is a difficult task. This study was conducted on a karst terrain in Sete Lagoas, Brazil, where rapid urban growth without adequate water resources management resulted in the drilling of unproductive wells and possible aquifer over-exploitation due to the concentration of wells. The objective was to develop a method for mapping groundwater potentiality for karst aquifers, serving as water resources management tool, based on 3D geological modelling, field work and pumping test data, remote sensing, geophysics analysis and production of thematic maps, resulting in the hydrogeological conceptual model. The groundwater potentiality map showed that most potential zones are on the central area, limited by grabens, where limestones are in contact with unconsolidated sediments, on areas with higher density of morphostructural and geophysical lineaments, mainly in east–west and north–east directions, near karst surface features, on thicker karstified zones, with higher recharge rates.

一种绘制巴西塞特拉戈斯市区岩溶地下水潜力的方法

摘要 由于复杂的水文地质背景，在岩溶地区绘制地下水潜势带是一项艰巨的任务。这项研究是在巴西 Sete Lagoas 的喀斯特地形上进行的，那里的快速城市发展没有适当的水资源管理，导致钻井不生产，并且由于水井集中，可能导致含水层过度开采。目标是开发一种绘制岩溶含水层地下水潜力的方法，作为水资源管理工具，基于 3D 地质建模、实地工作和抽水测试数据、遥感、地球物理学分析和专题图的制作，从而产生水文地质概念模型。地下水潜力图显示，大部分潜力区位于中心区，受地堑限制，
