In South Transdanubia (Hungary), the remarkable geothermal and hydrocarbon resources in the Drava Basin and the hypogene caves at the margin of outcropping carbonate hills were usually investigated separately and their interactions were hitherto neglected. The aim of this study is to give all these groundwater-related resources and phenomena a common framework applying the concept of regional hydraulic continuity, and to complete the regional (i.e., basin-scale) hydraulic assessment of the area based on preproduction archival measured data. Pressure-elevation profiles, tomographic fluid-potential maps and hydraulic cross-sections were constructed to determine the vertical and horizontal fluid-flow conditions. As a result, two kinds of fluid flow systems could be identified. Within the gravitational flow systems, horizontal flow conditions are dominant and the regional flow direction tends toward the S–SE. In deeper basin regions, an overpressured flow system is prevalent, where fluids are driven laterally from the deeper sub-basins towards their margins. Based on the regional-scale evaluation of fluid flow systems, conclusions could be drawn regarding the geothermal and hydrocarbon potential of the area. Additionally, local-scale phenomena could be explained, particularly in the southern foreland of the Villány Hills. Cave formation cannot be related to the present-day flow systems here. In the Harkány area, groundwater chemistry could be explained by fluid contribution from the Drava Basin. A comparison with the marginal Buda Thermal Karst area allows for generalized conclusions regarding the connections between marginal karst reservoirs and the Pannonian Basin.

在South Transdanubia（匈牙利），通常对德拉瓦盆地中显着的地热和碳氢化合物资源以及碳酸盐岩露头边缘的次生洞穴进行单独研究，而迄今为止它们之间的相互作用被忽略了。这项研究的目的是为所有这些与地下水有关的资源和现象提供一个应用区域水力连续性概念的通用框架，并基于生产前的存档测量数据完成该地区的区域（即流域规模）水力评估。 。构造了压力高程图，断层层析流体势图和水力横截面以确定垂直和水平流体流动条件。结果，可以识别两种流体流动系统。在重力流系统中，水平流动条件占主导地位，区域流动方向趋向于S–SE。在较深的盆地地区，普遍存在超压流动系统，在该系统中，流体从较深的次盆地向其边缘横向驱动。基于流体流动系统的区域规模评估，可以得出有关该地区的地热和碳氢化合物潜力的结论。此外，可以解释局部现象，尤其是在VillányHills的南部前陆地区。洞穴的形成与当今的水流系统无关。在Harkány地区，可以通过Drava盆地的流体作用来解释地下水的化学作用。
