Abstract

U ovom radu analizirana je hidraulička povezanost aluvijalnih i proluvijalnih naslaga zagrebačkog vodonosnika. U analizama su korišteni podaci s 3 piezometra na području aluvija zagrebačkog vodonosnika i 2 piezometra koji se nalaze u proluvijalnim naslagama u rubnom dijelu vodonosnika. Analizirani su podaci za razdoblje od 1.8.2015. do 25.8.2015. Primijenjene su sljedeće statističke metode: metoda korelacije, metoda linearne regresije i metoda kroskorelacije. Rezultati obrade podataka navedenim metodama prikazani su u obliku koeficijenata, dijagrama i jednadžbi. Dobiveni koeficijenti korelacije ukazuju na dobru hidrauličku povezanost aluvijalnih i proluvijalnih naslaga. Korištenjem linearnih regresijskih modela možemo prognozirati razinu podzemne vode u proluvijalnom dijelu vodonosnika pomoću razine podzemne vode u aluvijalnom dijelu, ali sa niskom pouzdanošću. Metodom kroskorelacije određeno je vrijeme kašnjenja reakcije promjene razine podzemne vode u proluvijalnom dijelu vodonosnika na promjenu razine podzemne vode u aluvijalnom dijelu vodonosnika.

Abstract: The thesis analyses the hydraulic connection between the alluvial and the proluvial deposits of the Zagreb aquifer. The analysis contains data form three piezometers in the alluvial part of the aquifer and two piezometers in the proluvial deposits in the marginal part of the aquifer. The data used in analyses date from August 1, 2015 to August 25, 2015. The following statistical methods were applied: correlation method, linear regression method and cross correlation method. The results of these analyses are presented in the form of coefficients, diagrams and equations. The resulting correlation coefficients are indicators of good hydraulic connection existing between alluvial and proluvial deposits. Using linear regression models we can forecast groundwater levels in the proluvial part of the aquifer by using groundwater levels from the alluvial part, but with a low level of accuracy. Cross-correlation method was used to determine the time delay between groundwater level changes in the proluvial part of the aquifer and the groundwater level changes in the alluvial part of the aquifer.
