In the past 30 years, in Serbia and Montenegro only, speleo-divers have investigated over 40 siphonal springs, active cave channels and ponors, of which more then 20 are a proof of deep siphonal circulation in karstic aquifers. The karstic springs are the most investigated phenomena from hydrogeological view point, and their investigations needs particular attention. Most of significant karstic springs are located on the rims of erosion basins - perimeters of karst poljes, river valleys, sea coasts and contact areas between karst aquifers and hydrogeological barriers. General characteristics of springs regime is the direct correlation between precipitation and spring discharge. Moreover, hydrogeological regime of these springs also depends on: size of the catchment area, karstic aquifer retardation capacity, total porosity, as well as lithological and structural characteristics.
