In protected mountainous areas, groundwater surveys are usually restricted to studies of their recharge by springs and streams. In the case of fissured rocks, which represent a highly heterogeneous medium, classical hydrogeological methods may be supplemented by electrical resistivity tomography (ERT) techniques. The studies presented here were focused on explaining issues related to groundwater circulation and recharge in such a complex structure, based on the study of Gorczyński Ravine situated within the Pieniny Klippen Belt. The groundwater of that area is recharged by the Macelowy Stream and its spring. Electrical conductivity of water (EC) measurements have indicated the existence of a privileged groundwater recharge zone of the stream and a different groundwater recharge zone of the spring. ERT surveys were used to explain the observed EC measurements. The analysed rock massif is clearly heterogenic, as documented by the wide range of electrical resistivity values, from c. 50 Ωm to above 19 000 Ωm. Interpretation of the results was limited by the lack of documentation from wells, which would have allowed precise correlation between geoelectrical layers and geological units. Despite these restrictions, ERT surveys facilitated the explanation of the observed hydrogeological phenomena and supplied new data on the complex structure of this part of the Pieniny Klippen Belt.
