AB  - This paper documents the change of temperature indices for the growing season (April–September) and dormancy (October–March) in Serbia based on observations from 26 meteorological stations. The mean, maximum, and minimum daily temperatures, as well as eight extreme temperature indices, were examined. A trend analysis revealed uneven changes in the growing season and dormant temperatures during the observation period divided into two parts (1961–1980 and 1981–2010) according to the results of the sequential Mann–Kendall test for detecting change points in time series. The dormant temperature changes were quite uniform during the entire examined period, while the growing season temperature displayed a complex pattern of change. In the sub-period 1961–1980, all examined temperature indices exhibited a cooling tendency during the growing season and a warming tendency during dormancy. A larger decreasing trend was detected in the growing season maximum temperature (a nationally averaged rate − 1.10 °C per decade) and related indices than in the growing season minimum temperature (a nationally averaged rate − 0.37 °C per decade) and related indices. In the same sub-period, the dormant maximum and minimum temperatures increased at the same rate of 0.49 °C per decade on average for all stations. During the sub-period 1981–2010, a warming tendency was detected both in the growing season and dormant temperature indices with similar magnitudes of the change (minimum and maximum temperatures increased on average from 0.48 to 0.56 °C per decade). Examination of the relationship between the temperature indices and large-scale circulation patterns revealed that only the East Atlantic pattern displayed significant association with trends of examined indices, but only during the growing season in the sub-period 1981–2010.

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  - The role of hydrological models in water management is significant. One of their important applications is the development and management of water resources, including water quality and sediment transport. Semi-distributed hydrological models, such as HBV-light, provide the possibility of dividing the catchment into sub-catchments and zones according to height and type of land cover. GIS tools provide significant support to prepare input for these models. The paper presents the methodology for preparing input data, using the QGIS tool, for the HBV-light hydrological model, which is used for continuous hydrological simulations. This model transforms precipitation from the catchment into runoff. Three alternative methods are described and compared within the methodology, based on the example of the Veternica river catchment.

AB  - Water table forecasting plays an important role in the management of groundwater resources in agricultural regions where there are drainage systems in river valleys. The results presented in this paper pertain to an area along the left bank of the Danube River, in the Province of Vojvodina, which is the northern part of Serbia. Two soft computing techniques were used in this research: an adaptive neurofuzzy inference system (ANFIS) and an artificial neural network (ANN) model for one-month water table forecasts at several wells located at different distances from the river. The results suggest that both these techniques represent useful tools for modeling hydrological processes in agriculture, with similar computing and memory capabilities, such that they constitute an exceptionally good numerical framework for generating high-quality models.

AB  - Applications of models that simulate the processes in crop production are very frequent in agricultural research. Possibility of application of EPIC model for soil moisture simulation is considered in this paper. Results of measurements of soil moisture in chernozem type of soil under sugar beet in the conditions of irrigated and rainfall regime within period 1987-1990 were used for the analysis of possibility of application of EPIC model in simulation of soil water content. Application of EPIC model for soil moisture simulation in both irrigated and unirrigated conditions are rather limited for application without calibration on irrigated soils. The model shows better result in soil with lower water content. Apart from model calibration for soil water content modelling it is necessary to use instruments for continual monitoring since longer and more reliable time series will help calibration and validation of the model for such purposes.

AB  - The region of Southeast Srem is rich in ground waters, which is of great significance to agricultural production. The objective of this paper was to designate the zones of different groundwater types from the aspect of recharge, based on the analysis of groundwater regimes in the study area. A very complex groundwater regime in Southeast Srem, which depends on a great number of natural and some anthropogenic factors, makes it difficult to designate clearly the zones of the three main types of groundwater regime. Still, the boundaries of the zones of groundwater regime types were defined based on the results of correlation analysis of the basic factors affecting the groundwater regime. Zone I includes the climatic type of groundwater. Its fluctuation corresponds to the vertical factors of water balance (precipitation and evaporation) and it is not affected by the river water level. This zone extends North and East of the line Putinci, Golubinci, Stara Pazova, Batajnica, Dobanovci, mainly in the area of the loess plateau. Within the zone, groundwater is at a relatively great depth. Only exceptionally, in the valleys, it appears almost on the surface. Zone II includes the climatic-hydrological groundwater type, which is the transition between the climatic type and the hydrological type. The fluctuation of groundwater regime is affected both by the effect of vertical balance factors, and by the effect of watercourses. Climatic-hydrological groundwater type covers the central and the lowest part of the study area and the South part of the middle terrace. Zone III is classified as the hydrological groundwater type and it covers the riparian areas along the Sava and the Danube. The aquifer is hydraulically connected with the river Sava.
AB  - Područje jugoistočnog Srema obiluje podzemnim vodama koje imaju veliki značaj za poljoprivrednu proizvodnju. Cilj ovog rada bio je da se analizom režima podzemnih voda posmatranog područja izdvoje rejoni sa različitim tipovima podzemnih voda sa stanovišta njihovog prihranjivanja. Veoma složen režim podzemnih voda na području jugoistočnog Srema, koji zavisi od velikog broja prirodnih i nekih antropogenih faktora, otežava jasnu rejonizaciju područja jugoistočnog Srema u odnosu na tri osnovna tipa režima podzemnih voda. Ipak, na osnovu rezultata korelacione analize osnovnih faktora koji utiču na režim podzemnih voda, definisane su granice rejona pojedinih tipova režima podzemnih voda.

Rejon II zahvata klimatsko hidrološki tip podzemne vode, koji je prelaz između klimatskog i hidrološkog tipa, kod koga se uočavaju i uticaj faktora vertikalnog bilansa, kao i uticaj vodenih tokova na režim oscilacija podzemne vode. Klimatsko hidrološki tip podzemne vode zahvata centralni najniži deo analiziranog područja i južni deo srednje terase. Rejon III su priobalne površine uz Savu i Dunav na kojima je zastupljen hidrološki tip podzemnih voda, na kojima je izdan u hidrauličkoj vezi sa rekom Savom.

abstract = "The region of Southeast Srem is rich in ground waters, which is of great significance to agricultural production. The objective of this paper was to designate the zones of different groundwater types from the aspect of recharge, based on the analysis of groundwater regimes in the study area. A very complex groundwater regime in Southeast Srem, which depends on a great number of natural and some anthropogenic factors, makes it difficult to designate clearly the zones of the three main types of groundwater regime. Still, the boundaries of the zones of groundwater regime types were defined based on the results of correlation analysis of the basic factors affecting the groundwater regime. Zone I includes the climatic type of groundwater. Its fluctuation corresponds to the vertical factors of water balance (precipitation and evaporation) and it is not affected by the river water level. This zone extends North and East of the line Putinci, Golubinci, Stara Pazova, Batajnica, Dobanovci, mainly in the area of the loess plateau. Within the zone, groundwater is at a relatively great depth. Only exceptionally, in the valleys, it appears almost on the surface. Zone II includes the climatic-hydrological groundwater type, which is the transition between the climatic type and the hydrological type. The fluctuation of groundwater regime is affected both by the effect of vertical balance factors, and by the effect of watercourses. Climatic-hydrological groundwater type covers the central and the lowest part of the study area and the South part of the middle terrace. Zone III is classified as the hydrological groundwater type and it covers the riparian areas along the Sava and the Danube. The aquifer is hydraulically connected with the river Sava., Područje jugoistočnog Srema obiluje podzemnim vodama koje imaju veliki značaj za poljoprivrednu proizvodnju. Cilj ovog rada bio je da se analizom režima podzemnih voda posmatranog područja izdvoje rejoni sa različitim tipovima podzemnih voda sa stanovišta njihovog prihranjivanja. Veoma složen režim podzemnih voda na području jugoistočnog Srema, koji zavisi od velikog broja prirodnih i nekih antropogenih faktora, otežava jasnu rejonizaciju područja jugoistočnog Srema u odnosu na tri osnovna tipa režima podzemnih voda. Ipak, na osnovu rezultata korelacione analize osnovnih faktora koji utiču na režim podzemnih voda, definisane su granice rejona pojedinih tipova režima podzemnih voda.

Klimatsko hidrološki tip podzemne vode zahvata centralni najniži deo analiziranog područja i južni deo srednje terase. Rejon III su priobalne površine uz Savu i Dunav na kojima je zastupljen hidrološki tip podzemnih voda, na kojima je izdan u hidrauličkoj vezi sa rekom Savom.",

AB  - The paper presents the results of comparative investigations of structuration degree, macro- and microaggregate stability of irrigated and non-irrigated type of carbonate clayey chernozem and non-carbonate clayey humogley soils within watering system in Surcin ( in the vicinity of Belgrade), where watering by sprinkling is carried out for more than 10 years. Due to the sprinkling, there occurred a degradation of the surface part (0-10 cm) of arable horizons, the aggregates of which are destructed by rain drops to a significant degree. The aggregates with the diameter of 10-5 mm are especially exposed to this process. The content of lumpy (>10 mm) aggregates in deeper parts (10-30 cm) of the arable horizon in the irrigated soils is significantly higher than in non-irrigated ones, while the ratio of agronomically most favorable aggregates (10- 0.25 mm) decreases, the decrease being much greater in chernozem than in the humogley soil. Under the influence of several years of sprinkling, the resistance of the structural aggregates to water of the investigated soils is also decreased, the lowest water resistance being present in the aggregates >3 mm of the surface part of the arable horizon. Several years of irrigation by sprinkling led to a degradation of microaggregate composition of the chernozem. However, in the irrigated humogley soil, microaggregates are more water resistant than in the non-irrigated one, which is supported by the data on the aggregation degree.
AB  - U ovom radu prikazani su rezultati uporednih istraživanja strukturnog stanja, makro i mikroagregatne stabilnosti navodnjavane i nenavodnjavane varijante karbonatnog ilovastog černozema i beskarbonatne glinovite ritske crnice u zalivnom sistemu u Surčinu (okolina Beograda), gde se zalivanje kišenjem vrši duže od 10 godina. Usled kišenja znatno je pogoršan agregatni sastav površinskog dela (0-10 cm) omičnog horizonata, čiji agregati su u znatnom stepenu razoreni kišnim kapima. Tom procesu su naročito izloženi agregati dijametra 10-5 mm. Sadržaj grudvastih (>10 mm) agregata u dubljim delovima (10-30 cm) orničnog horizonta u navodnjavanim zemljištima je znatno veći nego u nenavodnjavanim, dok se udeo agronomski najpovoljnijih agregata (10-0.25 mm) smanjuje, i to mnogo više kod černozema nego kod ritske crnice. Pod uticajem višegodišnjeg kišenja smanjena je i vodootpornost strukturnih agregata istraženih zemljišta, pri čemu najmanju vodootpornost pokazuju agregati >3 mm u površinskom delu orničnog horizonta. Višegodišnje navodnjavanje kišenjem dovelo je do pogoršavanja mikroagregatnog sastava černozema. Međutim, u navodnjavanoj ritskoj crnici mikroagregati su vodootporniji nego u nenavodnjavanoj, o čemu svedoče podaci o stepenu agregatnosti.
