Abstract
Hydrology studies are an important topic in the current research field due to increased human activity, translated in high demand of resources (fresh water, energy, process water) and pollution. The measurement of oxygen and hydrogen stable isotopes is an essential element in determining the origin, path and history of a water source. The aim of this paper was to obtain an isotopic map of the major water and energy source of Valcea County – the Olt River and it's affluents during autumn season. The isotopic composition of the water samples was determined by continuous-flow isotopic ratio mass spectrometry (CF-IRMS Delta V Plus) coupled with an isotopic equilibration module (GasBench II). The results provide a picture of the stable isotopes distribution in the Olt Valley Rivers. Differences between stable isotopes concentrations give us information about certain hydrological processes that took place.
