Sažetak
The physical, chemical and microbiological properties of karst springs change very rapidly in different hydrological conditions. Detailed monitoring of these changes and their comparison with precipitation and hydrological data enables analysis of flow dynamics and solute transport processes in the karst aquifers that feed these springs. Research to date (e.g. Kogovšek 2001 ; Vesper et al. 2001 ; Williams et al. 2006 ; Hunkeler & Mudry 2007 ; Ravbar et al. 2012) has shown that changes in the quality of karst water are most pronounced in the case of flood pulses caused by intense precipitation events following a long dry period. A special feature of karst is allogenic recharge with sinking streams from non-karst zones, which represents a concentrated input of frequently polluted water into the highly permeable conduits of a karst aquifer and onwards towards karst springs (e.g. Kogovšek 2002 ; Bailly-Comte et al. 2007 ; Pronk et al. 2007). The selected area of study in the transboundary area of the Northern Istria represents such a complex system, where diffuse infiltration in the highly permeable karst surface combines with concentrated recharge from sinking streams, and the diverse nature of recharge is also reflected in flow dynamics and solute transport. In order to better understand these processes, in June 2015 we carried out detailed monitoring of the quality of major karst water sources during two consecutive flood pulses following a dry period that had lasted since the end of March 2015, while at the same time monitoring precipitation and hydrological conditions.
