Abstract

Velebit je česta tema hidrogeoloških istraživanja zbog složenih struktura krša i
podzemnih tokova. Na istraživanom području Vršeljci – Srednji Velebit provedeno je
trasiranje krajem lipnja za vrijeme niskih voda što je rezultiralo niskim vodostajem u
vodonosniku špilje Atila i potocima Pećina i Tisovac. Za metodu istraživanja je odabrano
trasiranje Uraninom (Na-fluoresceinom), gdje se kvalitativnom metodom trasiranja
dokazivala povezanost mjesta injektiranja trasera i izvora na površini terena na kojima se
očekivala pojava trasera. Dokazana je veza između mjesta injektiranja i izvora u pećini H2O –
Vodena majka koji tvori potok Pećina, dok se boja na drugim predviđenim lokacijama nije
pojavila unutar vremena opažanja. Priložen je iskustveni opis cjelokupnog procesa planiranja
specijalnog hidrogeološkog projekta uz situacije i odluke s kojima se susreće hidrogeolog na
terenu i kako uspješno organizirati istraživanje trasiranja i terenskih eksperimenata. Ovim
diplomskim radom dokazana je veza između speleološkog objekta Atila i izvora potoka
Pećina, te je određena prividna brzina kretanja trasera kroz propusne karbonatne naslage
srednjeg trijasa na području Vršeljci – Srednji Velebit.

Abstract: Velebit is a frequent theme in hydrogeological studies due to complex structure of
karst and groundwater flows. In the investigated area Vršeljci - Middle Velebit was
conducted tracing at the end of during low water which resulted with low water levels in the
aquifer cave Atila and cave streams Pećina and Tisovac. For research method is selected
tracing Uranine (Na-fluorescein), where the qualitative method of tracing connections prove
tracer injection and sources on the ground surface on which appearance of tracer is expected.
It is a proven connection between injection and source in the cave H2O - Water Mother,
which forms a stream Pećina, while the color in other envisaged locations did not appear
within the time duration of the expedition. Attached is an empirical description of the entire
process of planning a special project with the hydrogeological situation and the decisions
facing hydrogeologists in the field and how to successfully conduct research tracing and field
experiments. This Master's Thesis demonstrated the link between the object Atila cave
streams and source cave, and is determined by the apparent velocity of tracer through
permeable carbonate deposits in the middle Triassic in Vršeljci - Middle Velebit.
