Abstract

Predmet istraživanja ovog diplomskog rada bili su uzorci vode iz četiriju horizonata tla, podzemne vode te oborine s područja vodocrpilišta Velika Gorica. Istraživanja su provedena tijekom veljače, travnja, svibnja i lipnja 2020. godine. Na uzorcima su određene koncentracije osnovnih iona, dok je na uzorcima podzemne vode pomoću Piperova dijagrama određen hidrogeokemijski facijes. Dobiveni rezultati ukazuju na povišene vrijednosti dušikovih spojeva u četvrtom horizontu istraživanog tla te snižene koncentracije iona u podzemnoj vodi. Razlog tome je proces nitrifikacije koji se odvija pri prijelazu u podzemnu vodu. Podzemna voda određena je kao kalcijsko – magnezijsko – hidrogenkarbonatni tip vode (CaMgHCO3). Analiza oborine pokazala je snižene koncentracije iona u odnosu na koncentracije iona iz uzoraka horizonata tla i podzemne vode. Također, analizirana je i povezanost količine oborine i vlažnosti tla. Povećanjem količine oborine udio vlažnosti u tlu raste do dubine od 160 cm.

Abstract (english)

The subject research of this thesis were water samples from four soil horizons, groundwater and precipitation from the area at Velika Gorica well field. The surveys were conducted during February, April, May and June 2020. The concentrations of basic ions were determined on the samples, while the hydrogeochemical facies was determined on the groundwater sample using the Piper diagram. The obtained results indicate elevated values of nitrogen compounds in the fourth horizon of the studied soil and reduced ion concentrations in groundwater. This is caused by the nitrification process that takes place during the transition to groundwater. Groundwater was determined as the calcium - magnesium - hydrogen carbonate type of water (CaMgHCO3). Precipitation analysis showed reduced ion concentrations relative to ion concentrations from soil horizon and groundwater samples. The relationship between precipitation and soil moisture was also determined. As the amount of precipitation increases, the moisture content of the soil increases up to a depth of 160 cm.
