AB  - Presented here is a study of the geochemical dynamics of the entire River Sava watershed, a major tributary of the River Danube which has not previously been investigated. The sampling was performed at 33 selected locations along the main channel of the stream and at its largest tributaries during three sampling seasons (fall 2005, spring 2006 and fall 2006), going from headwater locations to the mouth near the confluence with the Danube. Almost 80% of the solutes are derived from carbonate mineral weathering and represent over 50% of specific HCO(3)(-) flux normalized to unit basin area at the mouth of the Danube. Statistical analysis indicates that agricultural and industrial sources contribute significantly to increased Na(+), K(+), Cl(-), SO(4)(2-) and NO(3)(-) concentrations in tributary waters. Different processes control the water chemistry along the course of the Savas drainage-the upper reaches are largely regulated by contributions from carbonate mineral weathering, the middle reaches are influenced by agricultural activity and biological processes related to eutrophication, while the lower reaches tend to have more pronounced parameters related to the industrial processing along with leakages from municipal sanitary systems of these higher population density areas.

AB  - This paper presents the results of hydrological, physicochemical, biological, and isotopic investigations of the Danube River along the stretch through Serbian territory conducted during four campaigns in September and November 2007, September 2008 and April 2009. The stable isotope values exhibited significant changes both in the Danube (-10.7 to -9.5% for delta(18)O and -73.7 to -67.1% for delta(2)H) and in its tributaries (-9.1 to -8.5% for delta(18)O and -69.4 to -59.4% for delta(2)H) depending on the time of survey, which could be partly attributed to the influences of seasonal effects. Results emphasise the dominant role of tributaries inflows from aquifers along the Danube. The very narrow range of delta(13)C(POC) (from -28.9 to -27.4%) was associated with relatively high C/N ratios (C/N GT 9), and together with delta(15)N(TPN) values, the date suggested that, in early spring, a major fraction of particulate organic matter was derived from allochthonous matter. An orthogonal varimax rotation of the principal components analysis identified four latent factors (mineral related, biological, hardness, and soil inlets) which are responsible for the data structure covering 79% of the observed variations among the variables studied. A reliable grouping of samples with respect to the season was found.

AB  - Grab water samples were collected from the research ship ARGUS at four locations in Serbia, Ostruznica (17 rkm), Sabac (103.6 rkm), Sremska Mitrovica (136.4 rkm), and Jamena (195.0 rkm) from the mid-river, and near the left and right banks during longitudinal survey of the River Sava performed in August 2006. The stable isotope ratios of hydrogen and oxygen ((2)H/(1)H and (18)O/(16)O) were determined along with other physicochemical and biological parameters. The delta(18)O values of river water ranged from -9.2 parts per thousand to -8.5 parts per thousand, and delta(2)H values ranged from -66 parts per thousand to -61 parts per thousand. Samples taken from the mid-river along the main stem of the Sava at all examined locations appeared to be isotopically the same stream water with a value of -9.0 +/- 0.1 parts per thousand for delta(18)O and -65 +/- 1.0 parts per thousand for delta(2)H. The results are considered in relation to the isotopic changes known to occur in water subjected to evaporation and mixing.

AB  - Stable hydrogen and oxygen isotopes were analysed in water samples from the River Danube and its tributaries during a longitudinal survey performed in August 2005 on Serbian territory. Danube river water data ranged from -80 parts per thousand to -66 parts per thousand for delta(2)H, and from -11.2 parts per thousand to -9.3 parts per thousand for delta(18)O with delta values increasing downstream. The isotopic signatures of the adjacent tributaries (the Tisza, the Sava and the Velika Morava) sampled at the locations close to their confluence with the Danube (Titel, Ostruznica and Ljubicevski most, respectively) just about the time of the campaign were enriched (-67 parts per thousand and -63 parts per thousand for delta(2)H, and -9.3 parts per thousand and -8.9 parts per thousand for delta(18)O) with respect to the Danube water because of their catchment effects. Hydrogen and oxygen stable isotope values were used in combination with measured physico-chemical and biological parameters to trace hydrological and transport processes in these river systems. The mixing relationships between the Danube main stream and its tributaries were estimated using the mass balance for isotopic composition and electrical conductivity as conservative parameters. Evidence of an incomplete mixing process at the Centa location, 8 km below the confluence of the Tisza river, with its participation of 88% was shown by its oxygen-18 content. The correlations between river water isotope composition and physico-chemical and biological parameters are discussed.

AB  - The stable isotope composition of hydrogen (delta H-2) and oxygen (delta O-18) in monthly precipitation and river water (Sava River and Danube) samples in the Belgrade area gathered between 1992 and 2005 are determined. The local meteoric water line delta H-2 = 7.8 (+/- 0.2) delta O-18 + 7.3(+/- 1.6) (r(2) = 0.98, 11 = 60, sigma = 0.52) for the whole period of observation is close to the global meteoric water line. The amount-weighted mean delta H-2 and delta O-18 values of precipitation were -65 +/- 27 parts per thousand and -9.4 +/- 3.4 parts per thousand, respectively. Good correlation between delta O-18 values (r greater than or similar to 0.67) and ambient temperature and relative humidity was obtained. Stream-water data ranged front -94 to -60 parts per thousand for delta H-2 and from -11.0 to -5.7 parts per thousand. for delta O-18 with highly statistically significant difference (p GT 0.01) between the Sava River and the Danube. In addition, the isotopic compositions of local precipitation and adjacent river water at monitoring sites were compared. Obtained data will give an opportunity to improve the knowledge of mixing stream water and local groundwater, and assessment of potential groundwater risks and pressures in the Belgrade basin.
