Abstract

U ovom diplomskom radu određene su hidrogeokemijske značajke te izotopni sastav izvora Rakovac, potoka Rakovac i rijeke Bregane. Uzorkovanje vode izvršeno je na šest lokacija kroz šest mjeseci, od ožujka do kolovoza 2019. godine, jednom mjesečno. Određivane su koncentracije osnovnih iona pomoću dviju metoda: titracija i ionska kromatografija. Dobivene koncentracije poslužile su za određivanje hidrogeokemijskog facijesa koji su prikazani pomoću Piperovih dijagrama. Interpretacijom dobivenih rezultata uzorkovana voda prema svom ionskom sastavu pripada CaMgHCO3 (kalcijsko-magnezijsko-hidrogenkarbonatnom) tipu voda. Također, izmjeren je i izotopni sastav vode kako bi se odredilo podrijetlo vode na istraživanom području te njegova usporedba sa stabilnim izotopima u oborini Zagreba i Ljubljane. Dobiveni rezultati su pokazali kako se izotopni sastav istraživanog područja bolje poklapa s pravcem LMWL Ljubljana nego LMWL Zagreba što znači da je izotopni sastav izvora Rakovac, potoka Rakovac i rijeke Bregane sličniji oborini paloj u Ljubljani nego onoj u Zagrebu.

Abstract (english)

This thesis defines hydrogeochemical characteristics and isotopic composition of Rakovac spring, Rakovac stream and Bregana stream. Water sampling was performed at six sites over six months, from March to August 2019, once a month. Concentrations of basic ions were determined by two methods: titration and ion chromatography. The concentrations were used to determine the hydrogeochemical facies shown by Piper diagrams. By interpreting the results, the sampled water according to its ionic composition belongs to the CaMgHCO3 (calcium magnesium hydrogen carbonate) type of water. Also, the isotopic composition of water was measured to determine the origin of water in the study area and its comparison with stable isotopes in the Zagreb and Ljubljana rainfall. The obtained results showed that the isotopic composition of the study area coincides better with the direction of LMWL Ljubljana than LMWL Zagreb, which means that the isotopic composition of the Rakovac spring, the Rakovac stream and the Bregana stream is more similar to the rainfall in Ljubljana than in Zagreb.
