Later was confirmed this by water tracing tests above Planinska Jama and Pivka Jama. The dolines above Planinska Jama, separated from the cave by a 100 m thick layer of limestones, drain the rainfall water fast through the main, more permeable conduit. By a system of less permeable conduits which are associated with the main one, smaller quantities drain much more slowly. From the doline above Pivka Jama two highly permeable conduits lead through 40 m thick rock draining a significant amount of water. Around them several smaller conduits exist. The recharge area of the trickles is connected but their mutual links are of various permeabilitiesZa izdatnejše curke se predvideva, da se napajajo iz območij vrtač. To so ugotavljali s sledilnimi poskusi na območju Planinske in Pivke jame. Vrtača nad Planinsko jamo, ki jo ločijo od jame 100 m debeli apnenci, odvaja hitro in večje količine padavinske vode po glavnem, prepustnejšem prevodniku. Po spletu slabše prepustnih prevodnikov, ki so povezani z glavnim prevodnikom, pa se pretakajo počasneje manjše količine. Iz vrtače nad Pivko jamo vodita skozi 40 m debele kamnine dva prepustnejša prevodnika, ki odvajata večje količine vode. Spremlja ju večje število manjših prevodnikov. Zaledja curkov so med seboj prepletena, vendar so njihove medsebojne povezave zelo različno prepustneTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZRC SAZU
