Abstract
On Sinji vrh field site above Hubelj, a reference site for epikarst zone processes study (conf.: Association of Tracer Hydrology), we will continue to study transport proceses in unsaturated zone of karst aquifers. With tests, measurements and data analysis we will: 1) verify epikarst zone flow and (pollutant) transport conceptual model, elaborated from Sinji vrh data by research team member Barbara Čenčur-Curk (Doctoral thesis in redaction, Univ. of Ljubljana, 2001), 2) verify precipitation run-off partitioning model of karst aquifers, developed from one storm impacts for Sinji vrh - Hubelj system by research team member Branka Trček (Doctoral thesis in redaction, Univ. of Ljubljana, 2001), 3) enable monitoring of long term climatic change impacts on outflow and isotopic composition of water from karst aquifers; at Trnovski gozd, a 15 years observation period record exists for the purpose, 4) verify a laboratory derived karstification model of research team member Franci Gabrovšek (Doctoral thesis, Univ. of Bremen, Germany, 2000) by field data, 5) provide verification data for hypothesis that thick unsaturated zones of karst aquifers enable for partial multiannual storage of water (Metka Petrič, Doctoral thesis, Univ. of Ljubljana, 2000). Mass transport in soil and unsaturated zone of karst aquifers (with exception of karst channels and large fractures) is due to microfractures very slow and may last more than a decade. With this respect, past observation period at Sinji vrh (1995-2001) is rather short and the developed models require additional verification. In our research, we will use Sinji vrh experimental facility and artificial and natural tracers (isotopes of carbon, oxigen and hydrogen). We will have to upgrade our measuring equipment in soil and in unsaturated zone and our small water samples analytics. Flow and mass transport will be followed through soil, unsaturated and saturated zones of the aquifer or from rainwater to spring.
