Hydrogeological relations among well-fields of Koprivnica : master's thesis

Koprivnička vodocrpilišta nalaze se na području Koprivničke Podravine koja pripada strukturnoj jedinici Dravskog bazena. Crpilišta Ivanščak i Lipovec, smješteni na području Koprivničke Podravine međusobno se nalaze na relativno maloj udaljenosti, međutim istraživanja su pokazala različitu geometriju vodonosnika, hidrauličke značajke te razliku u prirodnoj kakvoći podzemne vode. U ovom diplomskom radu razrađen je utjecaj geoloških struktura na razliku hidrogeoloških značajki i kakvoće vode između crpilišta Ivanščak i Lipovec. Na crpilištu Ivanščak debljina vodonosnog kompleksa iznosi oko 40 metara, dok na crpilišu Lipovec debljina iznosi oko 150 metara. Pokazalo se da su uzroci ovih razlika uvjeti taloženja koji ovise o pokretima duž rasjeda, koji graniče s pojedinim strukturama.Abstract: The well-fields of Koprivnica are located in Koprivnička Podravina that belongs to Drava basin structural unit. Well-fields Lipovec and Ivanščak, located in Koprivnička Podravina, are positioned relatively close the each other. However, studies have shown different geometries of two aquifers, the difference in hydraulic characteristics and the difference in natural groundwater quality as well. In this paper, the impact of the geological structures on the difference in hydrogeological characteristics and on the difference in the water quality among the well-fields, Ivanščak and Lipovec, are elaborated. At the well-field Ivanščak, thickness of the aquifer complex is about 40 meters, while at the well-field Lipovec thickness of the aquifer complex is about 150 meters. It has been shown that depositional conditions are the main causes of these differences. Changes in depositional conditions depends on the movements along particular faults, which border the main geological structures in the area
