Abstract

The presented paper describes spatial and temporal variations in extended stable isotope datasets of hydrogen and oxygen (δ2H and δ18O) in the Sava River water that were used to estimate the mean residence time (MRT) of stream water using an exponential flow model. The re-examining MRT was <2 years in the Slovenian part of the Sava River and was in a good agreement with previous estimates and with the MRT estimated in the Sava River at Ostružnica near Belgrade, Serbia. A MRT >2.2 years was observed in the Danube River at Vinča also near Belgrade. The spatial distribution of δ18O in precipitation over the Sava River Basin (SRB) was mapped based on the long-term weighted mean annual δ18O values and established relationship with various geographical controls (latitude, longitude and altitude). The modelled δ18O values in precipitation agree with the measured values in the surface river water at different locations indicating that the spatial variation in the isotopic composition of precipitation is the dominant factor controlling surface water isotope ratios over the SRB.
