Sažetak
Several karst springs in the Gacka area of Croatia were studied using environmental tracers (stable isotopes (18O, 2H), tritium (3H), chlorofluorocarbons (CFCs) and noble gases (3He, 4He, Ar, Ne, Kr, Xe)). They provided valuable information regarding the mean residence time and age distribution of the spring waters. The variation of the precipitation’s isotopic signal in spring discharge indicates mixing of waters with different transit times. Comparison of CFC and 3H/3He data reveals that during the dry weather period some space in the karst groundwater systems is not filled with water. The results show that compared to single-tracer studies, multitracer techniques may allow a better understanding and characterization of the system.
