AB  - Ideja ovoga rada je da prikaže osnovne rezultate sprovedene sveobuhvatne analize malih voda Save i Drine u zoni ušća Drine. U radu se prikazuju kvantitativne karakteristike malih voda koje se najčešće koriste kao podloga pri projektovanju većine vodoprivrednih i hidrotehničkih objekata. Posebno je detaljno analizirana dužina malovodnih perioda ispod repernih protoka - protoka određenih za izabrana trajanja sa krivih trajanja srednjih dnevnih protoka. Primenjen je novi pristup koji, pored klasične probabilističke analize minimalnih godišnjih i minimalnih srednjih mesečnih protoka, obuhvata i analizu dužina neprekidnih malovodnih perioda sa protocima manjim od protoka karakterističih trajanja, njihovu unutargodišnju raspodelu i zastupljenost. Bazni podaci koji su korišćeni za proračun malih voda su zvanični podaci Državnog hidrometeorološkog zavoda Hrvatske iz Zagreba (DHMZ) i Republičkog hidrometeorološkog zavoda Srbije iz Beograda (RHMZ) na hidrološkim stanicama (HS) Županja i Sremska Mitrovica na reci Savi i Radalj na reci Drini.

AB  - This paper presents main results of a comprehensive analysis of low flows on the territory of the Republic of Serbia, south of the Sava and the Danube rivers. The results are a part of the forthcoming book on “Mean and low flows in small and medium watersheds in Serbia”, which is under development. The book is being produced jointly by the “Jaroslav Černi” Institute for Water Resources Management and Republic Hydrometeo¬ro¬logical Service of Serbia with participation of the University of Belgrade – Faculty of Civil Engineering and University of Niš – Faculty of Civil Engineering and Architecture. The analysis deals with the quantitative characteristics of low flows that are commonly used for design in various water management and hydraulic engineering projects, but are also a starting point in estimating the “minimum sustainable flow”, which is, according to the current Water Act, the minimum flow in the rivers needed for maintaining the biocenosis and for satisfying the demands of downstream users. The main outcomes of the comprehensive low flow analysis presented in this paper are the long-term mean flow, duration of daily flows and probability of exceedance of minimum mean monthly flows. Additionally, special attention is given to quantitative indices of length of intervals with flow below the specified thresholds, taken from the flow duration curve. A new approach applied includes, beside a classical statistical analysis of annual minima and mean monthly minima, a comprehensive analysis of continuous duration of low flows below the specified thresholds and their seasonal distribution. Basic data from 82 hydrological stations in small and medium-sized watersheds within Serbia south of the Danube and the Sava rivers are provided by Republic Hydromete-orological Service. All available data on daily and absolute annual minimum flows from the start of operation and 2018 are used in the analysis.

AB  - Maximum low flow durations, presented in this paper, are taken from the new book on “Mean and low flows in small and medium watersheds in Serbia”, which is jointly under development by the “Jaroslav Černi” Institute for Water Resources Management and Republic Hydrometeorological Service of Serbia with participation of the University of Belgrade – Faculty of Civil Engineering and University of Niš – Faculty of Civil Engineering and Architecture. Basic data from 82 hydrological stations in small and medium-sized watersheds within Serbia south of the Danube and the Sava rivers are provided by Republic Hydrometeorological Service. All available data on daily and absolute annual minimum flows from the start of operation and 2018 are used in the analysis. This paper presents a part of the results relating maximum low flow durations to characteristic thresholds and probability of occurrence, as well as their seasonal distribution. The results are averaged over individual watersheds and for the territory of Serbia.

AB  - U radu se razmatra određivanje srednjih voda na malim neizučenim slivovima u okviru teritorije Republike Srbije, na kojima ne postoje hidrološki podaci o mere-nim protocima. Razmatrana je metoda Langbajna u kojoj je formulisan parametar Θ čija vrednost u originalnoj formuli iznosi Θ = 0,886. Kao ulazni podaci u metodi Langbajna u ovom radu korišćene su prosečne višegodišnje padavine i temperature preuzete sa digitalnog repozitorijuma CarpatClim.

Primenom metode Langbajna sa originalnim pa-rametrom Θ, utvrđeno je neslaganje između osmotrenih srednjih protoka i računskih srednjih protoka na razma-tranim stanicama. Nakon toga izvršeno je tariranje para-metra Θ za svaku stanicu tako da računate srednje vode odgovaraju osmotrenim. Dobijene vrednosti parametra Θ su kartirane kako bi te karte poslužile za očitavanje parametra Θ na neizučenim slivovima. Ispitano je više metoda za interpolaciju karata kako bi se dobilo najbolje rešenje koje će dati najrealnije rezultate pri korišćenju karata za neizučene slivove. Utvrđeno je da se najtačniji rezultati dobijaju za interpolaciju Tisenovim poligonima (Nearest Neighbour) i metodom recipročnih rastojanja na deseti stepen (IDW 10). Krajnja verifikacija ocena parametra Θ izvršena je tako što su izabrane kontrolne stanice koje su isključene iz interpolacije, nakon čega su napravljene nove karte. Na osnovu dobijenih rezultata zaključeno je da su karte dobijene obema metodama interpolacije prihvatljive za ocenu parametra Θ, uz dodatni oprez na područjima sa karstom.

AB  - The authors present a detailed procedure for modelling of mean monthly flow time-series using records of the Great Morava River (Serbia). The proposed procedure overcomes a major challenge of other available methods by disaggregating the time series in order to capture the main properties of the hydrologic process in both long-run and short-run, The main assumption of the conducted research is that a time series of monthly flow rates represents a stochastic process comprised of deterministic, stochastic and random components, the former of which can be further decomposed into a composite trend and two periodic components (short-term or seasonal periodicity and long-term or multi-annual periodicity). In the present paper, the deterministic component of a monthly flow time-series is assessed by spectral analysis, whereas its stochastic component is modelled using cross-correlation transfer functions, artificial neural networks and polynomial regression. The results suggest that the deterministic component can be expressed solely as a function of time, whereas the stochastic component changes as a nonlinear function of climatic factors (rainfall and temperature). For the calibration period, the results of the analysis infers a lower value of Kling-Gupta Efficiency in the case of transfer functions (0.736), whereas artificial neural networks and polynomial regression suggest a significantly better match between the observed and simulated values, 0.841 and 0.891, respectively. It seems that transfer functions fail to capture high monthly flow rates, whereas the model based on polynomial regression reproduces high monthly flows much better because it is able to successfully capture a highly nonlinear relationship between the inputs and the output. The proposed methodology that uses a combination of artificial neural networks, spectral analysis and polynomial regression for deterministic and stochastic components can be applied to forecast monthly or seasonal flow rates.

It seems that transfer functions fail to capture high monthly flow rates, whereas the model based on polynomial regression reproduces high monthly flows much better because it is able to successfully capture a highly nonlinear relationship between the inputs and the output. The proposed methodology that uses a combination of artificial neural networks, spectral analysis and polynomial regression for deterministic and stochastic components can be applied to forecast monthly or seasonal flow rates.",

AB  - The authors propose a new approach for trend assessment that takes into account long-term periodicity of annual flows. In particular, analysis is performed of annual flows recorded at the locations of 30 operating and designed hydropower plants (HPPs) in Serbia, in order to assess the current and future water availability for hydropower generation. The composite annual trend is determined by sliding a fixed time window of 30 years along the observed time series with a one-year time step. Such a linear moving window (LMW) approach enables the identification of the flow trend as a median of all values for each time step. Significant trend harmonics are determined using discrete spectral analysis. The results show an alternation of upward and downward trend phases of different durations, namely: 6787, 33-43 and 21-29 years. On the other hand, the results of the Mann-Kendall test indicate a monotonic downward trend at the studied sites in the Drina River Basin, while statistically insignificant trends are noted at other river basins. The Mann-Kendall test with the Theil-Sen estimator also implies a downward and statistically insignificant flow trend after the observed period, whereas the LMW approach indicates a probable trend increase at all the examined sites. The proposed approach can be used to predict annual flows in order to establish long-term water management plans at hydropower plants.

AB  - The short-term predictions of annual and seasonal discharge derived by a modified TIPS (Tendency, Intermittency, Periodicity and Stochasticity) methodology are presented in this paper. The TIPS method (Yevjevich, 1984) is modified in such a way that annual time scale is used instead of daily. The reason of extracting a seasonal component from discharge time series represents an attempt to identify the long-term stochastic behaviour. The methodology is applied for modelling annual discharges at six gauging stations in the middle Danube River basin using the observed data in the common period from 1931 to 2012. The model performance measures suggest that the modelled time series are matched reasonably well. The model is then used for the short-time predictions for three annual step ahead (2013-2015). The annual discharge predictions of larger river basins for moderate hydrological conditions show reasonable matching with records expressed as the relative error from -8% to +3%. Irrespective of this, wet and dry periods for the aforementioned river basins show significant departures from annual observations. Also, the smaller river basins display greater deviations up to 26% of the observed annual discharges, whereas the accuracy of annual predictions do not strictly depend on the prevailing hydrological conditions.

AB  - Water resource has become a guarantee for sustainable development on both local and global scales. Exploiting water resources involves development of hydrological models for water management planning. In this paper we present a new stochastic model for generation of mean annul flows. The model is based on historical characteristics of time series of annual flows and consists of the trend component, long-term periodic component and stochastic component. The rest of specified components are model errors which are represented as a random time series. The random time series is generated by the single bootstrap model (SBM). Stochastic ensemble of error terms at the single hydrological station is formed using the SBM method. The ultimate stochastic model gives solutions of annual flows and presents a useful tool for integrated river basin planning and water management studies. The model is applied for ten large European rivers with long observed period. Validation of model results suggests that the stochastic flows simulated by the model can be used for hydrological simulations in river basins.

The time series of annual discharges are determined to be non-stationary. The trend varies in different time segments, with changing trend intensity and direction. Hurst analysis shows that the time series of annual discharges have a long memory. Long-term periodicity of annual time series is considered, while macroperiods are determined and classified into four groups of mean values: 9.5, 13.5, 22.5 and 31.5 years. Secondary microperiodicity is found to exist in the interval from 3.6 to 4.9 years.

AB  - Global warming affects the hydrological cycle and the long-term water budget of river basins. Flow variations have been noticed in the Danube River Basin, especially in its south-western parts where a downward trend in mean annual flows has been prevalent in the past several decades. Time series of mean annual and seasonal flows of the Sava River at hydrological stations Sremska Mitrovica and Zagreb are analysed in this paper. The trend is assessed with the Mann-Kendall test including the effect of serial correlation. Additionally, the trends are assessed in the multi-temporal framework. It is concluded that the long-term periodicity of annual flows has a considerable impact on the time series trend. Long-term component with cycles of 40 years in mean annual flows are detected by the time series analysis in frequency domain. Regression analysis showed a significant correlation between mean annual flows of the Sava River and annual precipitation, mean annual atmospheric pressure and air temperatures at meteorological station Ljubljana, as well as with the North Atlantic Oscillation (NAO) Index.

abstract = "Global warming affects the hydrological cycle and the long-term water budget of river basins. Flow variations have been noticed in the Danube River Basin, especially in its south-western parts where a downward trend in mean annual flows has been prevalent in the past several decades. Time series of mean annual and seasonal flows of the Sava River at hydrological stations Sremska Mitrovica and Zagreb are analysed in this paper. The trend is assessed with the Mann-Kendall test including the effect of serial correlation. Additionally, the trends are assessed in the multi-temporal framework. It is concluded that the long-term periodicity of annual flows has a considerable impact on the time series trend. Long-term component with cycles of 40 years in mean annual flows are detected by the time series analysis in frequency domain. Regression analysis showed a significant correlation between mean annual flows of the Sava River and annual precipitation, mean annual atmospheric pressure and air temperatures at meteorological station Ljubljana, as well as with the North Atlantic Oscillation (NAO) Index.",

AB  - 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.
AB  - 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.

AB  - The possible effects of water transfer through a tunnel from Fatnicko Polje to Bile a Reservoir on the hydrologic regime of the Bregava River located. in Eastern Herzegovina, in an area characterised by a predominantly karstic terrain, are studied. Three different simulation models of the area were developed and their predictions compared under a range of current and future hydrological and operational management conditions. These are based on a range of modelling approaches from a simplified conceptual approach to a quasi-physically based one. Despite the large complexity of the natural system, the models gave good fits to existing flow data with the most simplified model providing the closest agreement to historical flows. Calibrated models were used to study the possible effects of the intervention under a range of operational scenarios and identify the sources of the associated uncertainties. The results of the work suggest that the system of tunnels in question has a favourable effect in reducing flood hazard in the area, thus liberating scarce land resources for agriculture, and in reducing flows in the Bregava River (especially high flows). It is also suggested that a significant reduction in the uncertainty of modelling the karstic environment can be achieved by an appropriate, complementary combination of modelling approaches viewed as a multi-model ensemble.
