Abstract
This paper investigates the long-term changes in the hydrological time series. For this purpose, we use the trend analysis. The trend analysis is performed by using the standard Mann-Kendall trend test and by using the multi-temporal approach. The analysis is applied to the standardized and averaged time series of seasonal and annual flow of the river Sava at the stations Zagreb and Sremska Mitrovica for period from 1926 to 2005. It is concluded that the trend of seasonal and annual flow series of the Sava River are downward. The trends of annual flows in the region (Danube, Velika Morava, Lim) confirm this general pattern according to which the trends of annual flows in south-eastern Europe are downward. The multi-temporal analysis shows that the trend direction and intensity in the sub-series change with the long-term periodicity. The changes in trend direction and intensity depend on the length of the sub-series and the position of the sub-series within the whole time series.
U ovom radu analizirane su dugoročne promene u vremenskim serijama oticaja. Razmatrano je prisustvo trenda i višegodišnjih vodnih i sušnih ciklusa. Analiza trenda vršena je standardnim Mann-Kendall testom, a pored toga trend je analiziran korišćenjem tzv. multi-vremenskog pristupa u kojoj se trendovi računaju za podserije različitih početaka i dužina. Analiza je sprovedena na standardizovanim i osrednjenim serijama sezonskih i godišnjih proticaja na reci Savi na stanicama Zagreb i Sremska Mitrovica za period 1926-2005. Kada se posmatra ceo period, zaključuje se da je trend sezonskih i godišnjih proticaja na reci Savi opadajući. Trendovi godišnjih proticaja u širem području (Dunav, Velika Morava, Lim) su u skladu sa ovim rezultatima, dok reka Tisa poseduje rastuće trendove godišnjih proticaja. Multivremenskom analizom pokazano je da se trend razlikuje za različite podserije. Na smer i nagib trenda vremenskih serija utiče dužina serije kao i položaj podserije unutar cele serije. Promena ...smera i nagiba trenda ima ciklični karakter što odgovara smenama višegodišnjih vodnih i sušnih perioda.
