AB  - The catchment of the Toplica River, situated in an underdeveloped region of southern Serbia, is studied to examine the potential impact of climate change on the hydrologic regime of mountainous catchments. The study projects precipitation (P), air temperature (T), potential evapotranspiration (PET), and discharge (Q) in the entire catchment, as well as groundwater level (GWL) variation in the lowland part of the catchment, according to scenarios RCP4.5 and RCP8.5. Projections of P and T are based on the results of a multimodel ensemble of seven regional climate models from the EURO-CORDEX project. Runoff is simulated by a calibrated HBV-light model. The correlation between GWL and river discharge was modeled by soft computing techniques of artificial neural networks (ANN). The projections pertain to the period from 2021 to 2100. The Mann-Kendall trend test is used to check for a trend and its statistical significance, and the Mann-Whitney test to examine the statistical significance of a change in the mean ensemble median of time-series for the near future (2021-2050) and distant future (2071-2100), relative to the reference period (1971-2000). No notable changes are expected on an annual scale in the study area. However, the results show that the current non-uniformity of the monthly water distribution is growing. In the winter months at the end of the century, in RCP8.5, P and T are expected to increase, as is Q. Groundwater responds to increased river discharges by reduced depths to groundwater (increased GWL). A higher Q increases the flood risk in the winter months. In the warm season, RCP8.5 predicts a decrease in Q and increase in the depth to groundwater in the distant future. Reduced quantities of water in the warm period might have an adverse effect on drinking water supply, agriculture, hydropower, fisheries, ecology, and tourism in the study area.

AB  - In order to calculate water deficit of agricultural crops, it is necessary to have an insight into the evapotranspiration process. As for evaluation of reference evapotranspiration, the Penman-Monteith (FAO56-PM) method, suggested by The International Commission on Irrigation and Drainage (ICID) and Food and Agriculture Organization of the United Nations (FAO), requires several climate parameters, which are often unavailable. Thus, in this paper, the methods for computing ETo, which use limited weather data, were tested and then compared to FAO56-PM. The selected methods were those most often used as the replacement for FAO56-PM: Hargreaves, adjusted Hargreaves, Copais, Turc, Priestley-Taylor, Makkink and Hamon. ETo was calculated at the daily and average monthly levels, for the 2010 2013 period, using data from the following meteorological stations: Niš, Belgrade, Novi Sad, Loznica, Valjevo, Zlatibor, Ćuprija and Kikinda. Special importance was given to the vegetation period during the dry season due to the application of irrigation. The comparison of methods was based on statistical analysis, using parameters: MXE, MAE, RMSD, ARMSD, WRMSD, b and R2. The highest rate of matching FAO-PM at the average monthly level, as well as during the 2012 growing season, was shown by Copais, Turc and Priestley-Taylor methods, thus these methods may be recommended as the replacement for FAO-PM under climate conditions of Serbia. In case only temperature data are available, the results of this research justify the use of the adjusted Hargreaves equation to calculate ETo for the vegetation period.

Metoda Penman-Monteith (FAO56-PM), koja je od strane Međunarodne komisije za navodnjavanje i odvodnjavanje (engl. Internatioanl Commission on Irrigation and Drainage ICID) i Organizacije za hranu i poljoprivredu Ujedinjenih nacija (engl. Food and Agriculture Organisation FAO) predložena za proračun referentne evapotranspiracije (ETo), zahteva poznavanje više klimatskih parametara, koji često nisu dostupni. Zato su u ovom radu testirane metode za proračun ETo koje koriste manji broj podataka i upoređivane sa FAO56-PM. Izabrane su metode koje su najčešće korišćene kao zamena za FAO56-PM: Hargreaves, modifikovani Hargreaves, Copais, Turc, Priestley-Taylor, Makkink i Hamon. Proračun je rađen na dnevnom i prosečnom mesečnom nivou, za period 2010 2013. godine, na stanicama: Niš, Beograd, Novi Sad, Loznica, Valjevo, Zlatibor, Ćuprija i Kikinda. Poseban značaj dat je vegetacionom periodu tokom sušne godine, interesantnom sa aspekta primene navodnjavanja. Upoređivanje metoda rađeno je na osnovu statističke analize, pri čemu su korišćeni parametri: MXE, MAE, RMSD, ARMSD, WRMSD, b i R2. Najbolje slaganje sa metodom FAO-PM na prosečnom mesečnom nivou, kao i u letnjem periodu 2012. godine, pokazale su metode Copais, Turc i Priestley-Taylor, pa se one mogu preporučiti kao zamena za metodu FAO56-PM, u našim klimatskim uslovima. Ukoliko se raspolaže samo podacima o temperaturi vazduha, rezultati dobijeni u ovom istraživanju pokazuju opravdanost upotrebe modifikovane metode Hargreaves za proračun ETo u toku vegetacionog perioda.
