An example of identifying karst groundwater flow 总被引：3，自引：2，他引：1
Hydrogeological investigations for the purpose of regulating the karst aquifer were carried out in the mountain massif of
Kucaj in the Carpatho-Balkan range of eastern Serbia. Different geophysical methods were applied in order to identify the
position of karstified zones with active circulation of karst underground streams. Especially good results were obtained by
using the spontaneous potential method for the exploration and construction of boreholes and wells. In the valleys of Crni
Timok and Radovanska reka the measurements have been carried out upstream along the whole width of the alluvium to the limestone
periphery. A number of positive and negative anomalies have been recorded. In the centres of positive anomalies several boreholes
were located: HG-19 (centre of anomaly +30 mV, total length of the biggest cavern is 9 m); HG-1 (+20 mV, cavern of 2 m); HG-15
(max. +114 mV, effective cavernousness is 17%).
