Sažetak:
The paper summarizes results of 199 tracing tests with 623 positive connections. As well as in the other large European karst regions uranin was most often used tracer, but rodamin, lithium chloride, tritium, chromium 51 and bacteriophages were sporadically used too. The range of maximal flow velocities varies from 0, 01 to 32, 1 cm/s (0, 36 – 1155, 6 m/h), the average value is 3, 55 cm/s (127, 8 m/h) and median 2, 3 cm/s ( 82, 8 m/h). Maximal flow velocities lower than average values were observed at 66, 6 % of confirmed connections. The extremely high maximal flow velocities, that means higher than 10 cm/s (360 m/h), were determined at only 7.2 % of connections. The average distance between injection and observation site is 10, 93 km. The longest distance of 47.23 km was determined from Markov ponor in Lika region toward Novljanska Žrnovnica spring at the Adriatic coast. During the same experiment the distance between outermost springs with positive tracer detection was 69, 3 km.
