Abstract

U ovom radu, na temelju statističke analize vremenskih nizova podataka, pokušao se opisati utjecaj temperatura rijeke Save i geotermalnih anomalija na temperature podzemne vode zagrebačkog i samoborskog vodonosnika. U analizama su korišteni podaci o dnevnim temperaturama rijeke Save i podzemne vode mjereni od strane Državnog hidrometeorološkog zavoda (DHMZ). Primijenjene su sljedeće statističke metode: metoda korelacije, metoda linearne regresije i metoda kroskorelacije te su analizirane maksimalne, srednje i minimalne temperature podzemne vode. Rezultati obrade navedenim statističkim metodama prikazani su u obliku koeficijenata, dijagrama i karata. Pri obradi podataka utvrđeno je da se mjerenja dnevnih temperatura podzemne vode ne provode redovito, odnosno provode se u višemjesečnim intervalima. Zbog korištenja takvih nepotpunih setova podataka, pouzdanost rezultata obrade podataka je upitna. Analizom maksimalnih, srednjih i minimalnih temperatura podzemnih voda utvrđeno je da se maksimalne temperature kreću se između 11,5 ˚C i 26 ˚C, srednje u rasponu 10 ˚C do 18 ˚C, a minimalne variraju između 4 ˚C i 16,6 ˚C. Iz karti izotermi za maksimalne, srednje i minimalne temperature da se primijetiti da, uz postojanje određenih anomalija, temperature generalno rastu krećući se nizvodno od područja samoborskog vodonosnika prema zagrebačkom vodonosniku.

Abstract: In this paper, it was attempted to describe the effect of temperature of the Sava River and geothermal anomalies on the groundwater temperature of Zagreb and Samobor aquifer using the statistical analysis of time data series. The analysis features data for the daily temperatures of the Sava River and groundwaters measured by the Meteorological and Hydrological Services (MHS). Following statistical methods were used: correlation method, linear regression method and cross correlations method, as well as the analysis of the maximum, medium and minimum temperature of groundwater. Results of the above mentioned data processing are presented in the form of coefficients, diagrams and maps. This data processing showed that the daily measurements of groundwater temperature are not conducted regularly, as they are conducted in intervals of several months. Furthermore, due to the use of incomplete sets of data, reliability of the results of the data processing is questionable. By analyzing maximum, medium and minimum temperatures of groundwater it was found that maximum temperatures range between 11.5 ˚C and 26 ˚C, medium range from 10 ˚C to 18 ˚C and minimum vary between 4 ˚C and 16.6 ˚C From map of isotherms for maximum, medium and minimum temperatures can be noted that, with the existence of certain anomalies, temperatures generally increase moving downstream from Samobor aquifer area to Zagreb aquifer area.
