In an autonomous chapter of the scientific monograph published at Butterworth-Heinemann (Elsevier group), the main hydrogeological characteristics of the Malenščica spring and its karst catchment are summarized. The characteristics and importance of its exploitation for the water supply are presented. A description of the present state of its protection against various pollution sources is supplemented by the results of recent researches which will contribute to the improvement of this state and the implementation of modern methods of planning the protection of karst water resources.

In the article the time series analysis of recharge (precipitation, effective infiltration) and discharge data (discharge, slow and fast flow) was applied and tested. The results showed that in the assessment of karst systems with this method it is important to use effective infiltration rather than precipitation as the input function. However, the differences in the structure and degree of karstification of karst systems and the characteristics of groundwater flow have the most important influence on the results.

A detailed monitoring of water levels and temperatures of the Malenščica karst spring, as well as of the intermittent Cerknica Lake and Kotliči spring in its recharge area, indicated that the temperature is a good tracer in winter and summer periods, especially in the times when the Cerknica karst polje is flooded. A detailed analysis of the selected events enabled us to calculate the velocity of groundwater flow toward the Malenščica spring. The method can be used for assessment of transport velocities of contaminants at different hydrological conditions.

In the article the results of two multi-tracer tests with fluorescent tracers, which were carried out in May and November 2008, are presented and discussed. The aim of the tests was to characterize the properties of groundwater flow and transport of contaminants through the vadose zone and well developed system of karst channels in the epiphreatic and phreatic zone in different hydrologic conditions.

Access to many underground passages, theoretical knowledge and recent methods (modeling, water pressure-resistant dataloggers, precise sensors etc.) give us the opportunity to get better insight into the hydrodynamic aspect of caves. In the article some theoretical background of open surface and pressurized flow in underground rivers and present results of some possible scenarios are presented. Moreover, two case studies from the Ljubljanica karst basin are presented in more detail.
