AB  - Due to the improvement of computation power, in recent decades considerable progress has been made in the development of complex hydrological models. On the other hand, simple conceptual models have also been advanced. Previous studies on rainfall-runoff models have shown that model performance depends very much on the model structure. The purpose of this study is to determine whether the use of a complex hydrological model leads to more accurate results or not and to analyze whether some model structures are more efficient than others. Different configurations of the two models of different complexity, the Systeme Hydrologique Europeen TRANsport (SHETRAN) and Hydrologic Modeling System (HEC-HMS), were compared and evaluated in simulating flash flood runoff for the small (75.9 km(2)) Jicinka River catchment in the Czech Republic. The two models were compared with respect to runoff simulations at the catchment outlet and soil moisture simulations within the catchment. The results indicate that the more complex SHETRAN model outperforms the simpler HEC HMS model in case of runoff, but not for soil moisture. It can be concluded that the models with higher complexity do not necessarily provide better model performance, and that the reliability of hydrological model simulations can vary depending on the hydrological variable under consideration.

AB  - This paper presents the results of a study focused on the projected changes in extreme precipitation during the 21st century in Central Serbia. The changes are investigated on the basis of historical and modelled data sets of daily precipitation. The historical observation data were recorded at 18 synoptic weather stations in Central Serbia and modelled data were extracted from the regional climate model EBU-POM (Eta Belgrade University-Princeton Ocean Model) under the A1B scenario. The average number of days in a year with precipition  gt = 20, 30, 40 and 50 mm (R20, R30, R40 and R50), the share of daily precipitation above the 20, 30, 40 and 50 mm (P20, P30, P40, P50) in the total annual precipitation and the monthly distribution of these heavy daily precipitation are used as indices of changes in extreme precipitation. These indices, for the three periods 2011-2040, 2041-2070 and 2071-2100, are determined and compared with those obtained for the historical reference period 1961-1990. The results have shown that the main changes in extreme precipitation in Central Serbia will be in their spatial distribution, and the uncertainty of the occurrence of extreme events will decrease. In the future the increase will be more pronounced than the decrease of these indices. We strongly emphasize the benefit of this paper for both the prevention of natural disasters in the study area and for the improvement of the regional climate model.

AB  - The knowledge of spatio-temporal dynamics of soil moisture within the catchment is very important for rainfall-runoff modelling in flood forecasting In this study the comparison between remotely sensed soil moisture and soil moisture estimated from the SHETRAN hydrological model was performed for small and flashy Jieinka River catchment (75.9 km(2)) in the Czech Republic. Due to a relatively coarse spatial resolution of satellite data, the satellite soil moisture data were downscaled, by applying the method developed by Qu et al. (2015). The sub-grid variability of soil moisture was estimated on the basis of the mean soil moisture for the grid cell and the known hydraulic soil properties. The SHETRAN model was calibrated and verified to the observed streamflow hydrographs at the catchment outlet. The good correlation between the two different soil moisture information was obtained according to the majority of applied criteria. The results of the evaluation criteria indicate that the downscaled remotely sensed soil moisture data can be used as additional criteria for the calibration and validation of hydrological models for small catchments and can contribute to a better estimation of parameters, to reduce uncertainties of hydrological models and improve runoff simulations.

AB  - Hydrologic models are important for effective water resources management at a basin level. This paper describes an application of the HEC-HMS hydrologic model for simulations of flood hydrographs in the Lukovska River basin. Five flood events observed at the Merćez stream gauge were available for modelling purposes. These events are from two distinct periods and two seasons with different prevailing runoff generation mechanisms. Hence the events are assigned to either "present" or "past", and "spring" or "summer" group. The optimal parameter sets of each group are obtained by averaging the optimal parameters for individual events within the group. To assess model transferability, its applicability for simulation of flood events which are not considered in the model calibration, a cross-validation is performed. The results indicate that model parameters vary across the events, and that parameter transfer generally leads to considerable errors in hydrograph peaks and volumes, with the exception of simulation of summer events with "spring" parameters. Based on these results, recommendations for event-based modeling are given.

AB  - The objective of this study is to perform a sensitivity analysis of the SHETRAN model on the example of the torrential Lukovska River catchment in Serbia. The sensitivity analysis of the model was performed for the following parameters: the vertical saturated hydraulic conductivity of the subsurface soil, the horizontal saturated hydraulic conductivity in the saturated zone, the Strickler roughness coefficients for overland flow and for streams, the available water content in the soil and the erodibility coefficients due to rain and due to overland flow. It can be concluded that the water and sediment discharge are very sensitive to the values of the vertical saturated hydraulic conductivity of the subsurface soil in the range of 0.001 to 0.1 m/day; to the values of the horizontal saturated hydraulic conductivity in the saturated zone in the range of 0.01 to 5 m/day and to the values of the Strickler's coefficients for overland flow and for rivers in the range of 0.1 to 100 m1/3s-1 and 15 to 40 m1/3s, respectively. The sediment concentrations in a flow and sediment discharge are very sensitive to the values of erodibility coefficient due to overland flow in the range of 0.5 to 1.5 mg/m2s and to the values of erodibility coefficient due to rain in the range between 0.1 and 40 J1. The obtained results could be used to simplify the parameter calibration procedure and to facilitate estimation of parameters in ungauged mountainous basins of similar characteristics.

AB  - In the present study the SHETRAN river basin modelling system was used in conjunction with Geographic Information System (GIS) to estimate potential erosion and deposition rates within the catchment and the concentrations of sediment in a flow at the catchment outlet on the example of the 114.31 km(2) mountainous torrential Lukovska River catchment in Serbia. The streams in the Lukovska River catchment are short, steep and often produce hazardous torrential floods as a consequence of strong rainfall of short duration. The soil erosion and sediment discharge were analysed in view of the catchment response to physical characteristics of the catchment. Considering that the most of total annual sediment discharge in watersheds of torrential character is achieved during storm events, the SHETRAN modelling system was calibrated on the example of a storm event in 1986 and validated for three other storm events in 1974, 1976 and 1979. The simulated results of discharges and sediment concentrations at the catchment outlet for both calibration and validation events were compared with the observed data and found to be reasonable. The changes of erosion and deposition rates within the catchment and in the course of time were estimated for the calibration event in 1986. The simulated erosion rates were within the range of 1 to 10.5 t/ha and corresponded to the observed rates of erosion in Europe during extreme rain events. The presented methodology is useful in identifying the erosion vulnerable regions in a catchment where erosion control measures should be implemented.

AB  - Evapotranspiracija je jedan od najznačajnijih procesa unutar hidrološkog ciklusa, čija pouzdana procena je od suštinske važnosti pri planiranju i upravljanju zemljišnim i vodnim resursima i, od čije veličine direktno zavise potrebe biljaka za vodom. U radu je izvršeno poređenje proračunatih vrednosti referentne evapotranspiracije primenom metode FAO Blaney-Criddle-a, FAO Radijacione metode, metode FAO Penmana i FAO 56 Penman-Montejeve metode sa rezultatima lizimetarskih merenja u Košutnjaku tokom vegetacionih sezona u 2004., 2005. i 2006. godini. Pokazano je da se primenom FAO 56 Penman-Montejeve jednačine dobijaju rezultati najpribližniji rezultatima lizimetarskih merenja, zbog čega se preporučuje primena ove metode pri oceni referentne evapotranspiracije.
AB  - Evapotranspiration is one of the most important processes within the hydrological cycle whose reliable assessment is essential in the planning and managing of land and water resources. Besides that, the water needs of plants depend directly on the size of evapotranspiration. This paper presents a comparison of reference evapotranspiration values calculated using the FAO Blaney-Criddle method, the FAO Radiation methods, the FAO Penman and the FAO 56 Penman-Monteith method with the results of measurements of evapotranspiration at the meteorological station in Košutnjak during the growing seasons of 2004, 2005 and 2006. It is shown that the application of the FAO 56 Penman-Monteith equation provides the calculated values of evapotranspiration that are closest to the results of measurement and it is recommended to apply this method for the estimation of reference evapotranspiration.

AB  - During dry periods, the flow of medium and small streams is significantly reduced and equal to groundwater flow. Since the base flows provide information about aquifer characteristics and retention characteristics of a basin, the possibilities of analysis and simulation of base flows gain importance under the conditions of intensive water use and the increasing demand for adequate water quality protection. In this paper, a model was established and used for the description of the principles governing the changes of base runoff on the basis of a streamflow hydrograph registered at the outlet of the basin on the example of the Kolubara basin up to the 'Valjevo' profile. Since the amount of base runoff from a basin cannot be measured, the results of base flows obtained using the local minimum method were adopted as the criterion for the comparison of the modeled values of base runoffs. The created model was applied for making simulations of the base runoff hydrograph during three characteristic years (rainy 1970, average 1985, and dry 1990). Deviations between the base flow values obtained using the established model and by applying the local minimum method are acceptable from the standpoint of general hydrological accuracy.

AB  - This study presents a physically founded hydrologic-hydrautical model for determining the base flow of the catchment by analysing the water balance of the basin and vertical exchange of water between the atmosphere, unsaturated media and ground water, basing on the known physical characteristics of the basin (climatic, paedological, geological and vegetation ones) on the example of the 340 km(2) Kolubara River basin up to "Valjevo" water level monitoring station in Serbia in three characteristic years: an extremely rainy year (1970), an average year (1985) and an extremely dry year (1990). Taking into consideration that the amount of base flow of a basin is impossible to measure at the catchment outlet, the hydrograph of the base flow values obtained by separating from the streamflow hydrograph registered at the outlet of a drainage basin by application of the graphical local minimum method was used for checking the model's functioning. It was finally determined that the total base flow values at the outlet point of the catchment, obtained by application of the graphical local minimum method, equal approximately the total groundwater recharge from the whole surface area of the basin, representing the summary of groundwater recharge originating from different soil types covered with different types of vegetation, under the influence of atmospheric conditions of the soil surface. Thus it was confirmed that when characteristics of a basin are known, it is possible to obtain information on the base flow values.
