20.500.12556/DKUM-61435 Tok vode in onesnaževal skozi nenasičeno sredino Flow of water and pollutants through unsaturated zone V magistrskem delu smo naredili simulacije toka padavinske vode in onesnaževala skozi nenasičeno cono vodonosnika na Apaškem polju s programom HYDRUS 1D. V ta namen smo pregledali obstoječo zakonodajo in navedli pomembne člene posamičnih uredb. Prav tako smo opisali teoretično dogajanje v nenasičeni coni, podrobneje obravnavali dušikov cikel v njej in fizikalni princip toka tekočine in transporta onesnaževala. Kot onesnaževalo smo v magistrski nalogi upoštevali razpadajoče gnojilo urea. Gnojilo urea razpade vse do nitrata, kateri je problematičen v vodonosniku na Apaškem polju. Izdelana je bila tudi validacija modela na primeru nitrifikacijske verige. Simulacije smo naredili za dva različna profila tal, in sicer za profil tal v Podgradu in profil tal v Segovcih ob Muri. Using the software HYDRUS 1D, we made simulations of water and pollutants flow through unsaturated aquifer zone of Apaško polje. We reviewed existing legislation and stated relevant articles of the acts. We described the action in unsaturated zone, described nitrogen cycle and the flow of water and pollutants. As its final stage represents nitrate, we used urea decay chain mechanism as pollutant source. Nitrate is problematic in most aquifers. We also made validation on example of nitrification chain. Simulations were made for two different soil profiles. The first soil profile was made for Podgrad and second soil profile was made for Segovci ob Muri.
