That karst water is water discharged from karst springs which posses characteristics, primarily that of calcium content, indicating solution during the passage of that water across and through karst limestone. that part of karst spring water which is derived from watercourses sinking into the rock (and therefore originates mainly on impermeable rock) is said to be allogenic; that which derives from precipitation over the karst area alone is said to be autochthonous - the distinction between resurgence and exsurgence waters [19].?

UNDERGROUND WATER FLOW BETWEEN BLOKE PLATEAU AND CERKNICA POLJE AND HyDROLOGIC FUNCTION OFKRIŽNA JAMA, SLOVENIA

Abstract:
Križna jama and Križna jama 2 are of important natural value. They have been known for more than hundred years from spe­leobiological, paleontological, geomorphological and touristic points of view. In 2007 the establishment of a water treatment plant on Bloke plateau raised important question: can partly cleaned water from the water treatment plant contaminate both caves and decrease their value? To answer this question a tracer test was carried out at the Bloke plateau. It showed gen­eral underground water flow from Farovš?ica ponor at Bloke plateau toward the Šteberš?ica spring at Cerknica polje. Mi­nority of recovered tracer appeared at Žerovniš?ica and Izvir v Podložu springs. The tracer was not detected at Studenec v Ložu and Zlatovec springs. Between ponor and springs three karst caves were observed. The highest concentration of tracer was detected in the cave Mrzla jama pri Blo?icah and a much smaller concentration in the Križna jama and Križna jama 2. This shows that at middle water level the underground Farovš?ica stream does not flow directly through Križna jama and Križna jama 2 but near or below them. Since the tracer ap­peared in both caves only after the precipitation, underground water course can be significantly different at high water level. Tracing test also showed some characteristics of underground water flow through dolomite and characteristics of a composed aquifer with alogenic-autogenic recharge.
