Abstract
Hydrogeological conditions in karst areas reflect the high velocities of groundwater movement in open or material-filled channels. Usually they remain hidden under the ground, and only high flow rates of the flowing underground water reveal them. An example is one of the largest karst springs in Bulgaria – Glava Panega in the village of Zlatna Panega. There are two hydraulically connected lakes close to the spring head. The purpose of the present study is to establish this relationship, as well as to provide a more accurate information of groundwater discharge zones in the lake near the source of groundwater. The methods used include analyzing specific information from speleological studies, combined with conducted on field geophysical studies. Profiling was carried out using the method of the self potential, as well as research with the determination of the values of the natural electromagnetic field. The obtained results support the understanding of the behavior of the karst system in the area of the Glava Panega spring.
