Identification of the predominant recharge/discharge zones of the Zaprešić- Samobor aquifer using the analysis of the flow duration curves of Sava river and groundwater levels : master’s thesis

Cilj ovog rada bio je odrediti zone samoborsko-zaprešićkog vodonosnika u kojima rijeka Sava drenira ili prihranjuje vodonosnik. Analizirani su vodostaji rijeke Save i razine podzemne vode na temelju krivulja trajanja. Određene su hiporheične zone samoborsko-zaprešićkog vodonosnika pomoću karti ekvipotencijala za niske i srednje vode. Izdvojeno je sedam piezometara u području oko rijeke Save i četiri hidrološke postaje pomoću kojih su izrađena četiri profila na kojima su izvršene analize. Izdvojeni piezometri i hidrološke postaje su statistički obrađeni za razdoblje od 2003. do 2012. godine. U radu su prikazane krivulje trajanja vodostaja i razina podzemne vode, a također su izrađene i tablice za rezultate analize pojedinih godina unutar analiziranog razdoblja.Abstract: The goal of this thesis was to determine zones of Samobor-Zaprešić aquifer in which Sava river discharges or recharges it. Water lavels of Sava river and groundwater levels were analyzed based on flow duration curves. Hyporheic zones Samobor-Zaprešić aquifer were determined using the head contour maps for low and medium water levels. There were selected 7 piezometers and 4 hydrological stations which were used to create 4 cross-sections that were analyzed. Chosen piezometers and hydrological stations were statistically processed for period 2003 until 2012. Flow duration curves and groundwater levels were shown and also tables were maid to show analysis results for certain years within analyzed period
