“…The results �ave s�own t�at t�e rec�arge area of t�e spring is a binary karst �ydrological system. Recently, several tracer tests were carried out to investigate t�e spring and its catc�ment (Kogovšek 1999;Kogovšek et al 1999;Kogovšek et al 2008;Gabrovšek et al 2010), but its functioning in different �ydrological conditions is still not sufficiently investigated. So far, no time series analysis �as been performed in t�e area.…”

Izvleček UDK 556.33(497.4) Gregor Kovačič: Hidrogeološka študija kraškega izvira Malenščica (JZ Slovenija) z metodo analize časovnih vrst Kraški vodonosniki se pogosto preučujejo z uporabo metode analize časovni� vrst, vendar so raziskave, ki vključujejo veliko število prostorsko razporejeni� časovni� vrst, zelo redke. Raziskave, ki poleg padavin, vodostajev in pretokov vključujejo tudi druge tipe �idrološki� časovni� vrst, so prav tako redke. Predstavljena raziskava vodonosnika kraškega izvira Malenščica poudarja uporabnost �kratne avtokorelacijske in križnokorelacijske analize različni� dnevni� in urni� �idrološki� časovni� vrst, kot so pretoki, vodostaji, temperature, specifična električna prevodnost in padavine na regionalnem nivoju. Rezultati avtokorelacijske analize kažejo, da je skladiščna zmogljivost izvira Malenščica srednja, kar ne kaže na slabšo zakraselost sistema, ki ga označuje prevladujoča kanalska prevodnost. To nakazuje, da imajo la�ko dobro zakraseli sistemi kompleksnejše zgradbe daljši spominski učinek kot dobro zakraseli sistemi enostavnejše �idrogeološke zgradbe. Rezultati križnokorelacijske analize kažejo, da kraški izviri in vodotoki na preučevanem območju na precej �omogene padavine reagirajo �itro in �krati, vendar pa različno intenzivno. V taki� primeri� iz križnokorelacijske analize med padavinami ali pretoki kot vnosi ter izviri kot iznosi iz sistema ni mogoče dobiti zadovoljivi� informacij o �idrogeološkem delovanju sistema, medtem ko rezultati križnokorelacijske analize časovne vrste specifične električne prevodnosti dajejo koristne informacije o njegovem delovanju in ji� la�ko preprosto primerjamo z rezultati sledilni� poizkusov. Pri kompleksni� kraški� sistemi� kaže časovna vrsta temperatur omejene možnosti uporabe. Primerjalna analiza rezultatov analize časovni� vrst med zaporednimi �idrološkimi leti je pokazala, da na rezultate navedene analize močno vpliva izbira preučevanega �idrološkega leta.

“…Tracer tests have proven to be a valuable research tool in various other applied projects (Kogovšek 1999;Kogovšek et al 1999;Kogovšek and Petrič 2004;Petrič and Š ebela 2005;Kogovšek and Petrič 2006;Petric 2007, 2010a). In recent years, a series of tracer tests were carried out, and their results were used as the basis for planning the monitoring of water quality in the influence areas of various pollution sources (e.g., landfills, military training area, petrochemical depot, roads and expressways, railways).…”

The comprehensive knowledge of karst surface, caves, waters and biodiversity were examined with special emphasis on planning for environmental management and land use in karst regions using examples of projects performed by the staff from the Karst Research Institute ZRC SAZU. Based on the knowledge of karst, karst phenomena, karst waters and karst biodiversity, karstological monitoring was developed throughout the construction of expressways and planning for railways on karst terrain. Newly revealed karst phenomena were properly preserved. Regular climatic and biological monitoring were developed and implemented, as well as karstology consultation with an emphasis on the impact of the use of caves as natural assets. To understand karst, its evolution dynamics and processes, models were developed with which the study of the risk posed by dam site construction in karst areas was possible. Karst aquifers and their protection were studied using tracer tests and different methods of the transfer of contaminants through the vadose zone and underground flow connections. In assessing the vulnerability and contamination risk of groundwater, a comprehensive method was elaborated. Microorganisms and fauna of dripping water in caves were used as monitors of cave ecosystem health. By applying high-quality karstological research results from individual spheres of karstology and interdisciplinary studies, a foundation for sustainable planning of life in karst regions that will consider the natural and cultural characteristics and vulnerability of karst landscapes has been established.

“…To the north, the Pivka River sinks into the world-famous Postojna Cave to re-emerge a couple of times and eventually join the Sava and Danube. To make the situation even more complicated, there are four known bifurcation sites of the Pivka River, where subterranean and surface waters from both basins intermix during periods of high groundwater levels (Habič, 1989;Kogovšek et al, 1999;Ravbar and Šebela, 2004). To make the situation even more complicated, there are four known bifurcation sites of the Pivka River, where subterranean and surface waters from both basins intermix during periods of high groundwater levels (Habič, 1989;Kogovšek et al, 1999;Ravbar and Šebela, 2004).…”

“…Some 10 km to the south, at the other end of the polje, the water is draining mostly to the subterranean Reka (Timavo) River, which is part of the Adriatic basin (Gams, 2004). To make the situation even more complicated, there are four known bifurcation sites of the Pivka River, where subterranean and surface waters from both basins intermix during periods of high groundwater levels (Habič, 1989;Kogovšek et al, 1999;Ravbar and Šebela, 2004). The area is arguably the richest in the world in terms of subterranean aquatic biodiversity (Sket, 2012).…”

DNA barcoding sheds light on hidden subterranean boundary between Adriatic and Danubian drainage basins

In principle, the distribution of freshwater fauna follows the extent of drainage basins, but various historical and concurrent factors weaken this correspondence. Subterranean karstic drainages can be particularly baffling as their boundaries are decoupled from the surface relief and change with the level of the karstic groundwater. We explored how the distribution and genetic structure of cave fauna correlate to data obtained by conventional groundwater tracers in the Danubian-Adriatic divide in the classical Karst between Postojna and Trieste. Here, waters from the Pivka Polje drain to either basin, depending on the water level. This ambiguity is reflected by the distribution of several aquatic cave species that disperse from one drainage to the other. However, using DNA barcoding methods, we found a clear-cut separation between the closely related subterranean aquatic isopods Asellus aquaticus on the Danubian and Asellus kosswigi on the Adriatic side. The boundary between them agrees with the established hydrology at normal water levels. Further phylogeographic and demographic analyses suggest that the superficial concurrent correspondence has a deeper historical component. We inferred that the Adriatic species did not reach its present boundary by recent range dispersal, but rather has remained there as relict from Pleistocene times. Today, dispersal from the lower part of the Adriatic (Reka River) drainage is impossible because of the large altitudinal difference within. These results demonstrate that biological and particularly genetic groundwater tracing have the advantage of being sensitive to both historical and contemporary groundwater connectivity. Figure 4.
