A tracing test with injection of uranine in the sinking stream Tr¾i¹èica (SE Slovenia) was carried out at the hydrological conditions of recession from medium to low waters. Concentrated flow towards the springs Tominèev studenec, Javornikov izvir and Debeljakov izvir near the village Dvor in the Krka valley was proved. Apparent flow velocities between 2.4 and 4.6 cm/s were obtained, and the share of recovered tracer was estimated to 2/3 of the injected amount. In the Podpe¹ka jama cave the tracer in lower concentrations was detected only after heavy rain occurred after two months of low water. The apparent flow velocity of 0.1 cm/s was calculated. Obtained results, together with the outcomes of the previous tracing tests, indicate that hydrological conditions significantly influence the underground water flow from the Tr¾i¹èica sinking stream.
