Abstract

U ovom radu određivana je hidraulička vodljivost metodom koja se temelji na empirijskim
formulama uz korištenje podataka o granulometrijskom sastavu porozne sredine. Vrijednosti
hidrauličke vodljivosti dobivene su izračunom u MS Excelu pomoću šest empirijskih formula
(Slichter, Beyer, Hazen, Kozeny-Carman, Alyamani i Sen, USBR), a ukupno je analizirano 40
uzoraka s područja vodocrpilišta Osekovo. Budući da je na istraživanom području u
vertikalnom slijedu naslaga izražena heterogenost vodonosnika, vrijednosti hidrauličke
vodljivosti variraju u širokom rasponu. Minimalna vrijednost iznosi 8,825x10-9 m/s za uzorak
prašinastog pijeska, dok maksimalna vrijednost iznosi 1,404x10-2 m/s za uzorak pjeskovitog
šljunka. Također, primjena različitih empirijskih formula na istom poroznom mediju može
dati različite vrijednosti hidrauličke vodljivosti odnosno može dovesti do njihovog
podcjenjivanja ili precjenjivanja.

Abstract (english)

Abstract: In this study the hydraulic conductivity is determined by a method which is based on
empirical formulas using data about a grain-size composition of porous media. Result values
were calculated in MS Excel using six empirical formulas (Slichter, Beyer, Hazen, Kozeny-
Carman, Alyamani and Sen, USBR) and total of 40 samples were analyzed in the area of well
field Osekovo. In the study area, in the vertical sequence of sediments, heterogeneity aquifer
is pronounced, so the values of hydraulic conductivity can vary in wide range aspect. The
minimum value is 8,825x10-9 m/s for a sample of silty sand, and the maximum value is
1,404x10-2 m/s for a sample of sandy gravel. Also, the use of different empirical formulas on
the same porous media can give different values of hydraulic conductivity that may lead to
their underestimating or overestimating.
