STUDY OF SPATIAL AND TEMPORAL VARIATIONS OF SOME PHYSICOCHEMICAL PARAMETERS OF THE LOWER SIRET RIVER

The present paper presents the variability of some physicochemical parameters of the Siret river. Measurements were made partially by responsible authorities in charge with water management and by the environmental laboratory of the European Centre of Excellence for the Environment (ECEE) of Dunarea de Jos University of Galati. The monitoring was carried out for three years in order to observe the seasonal variation of the characteristics of the Siret river and their influence on some physicochemical parameters. Our results show that physical parameters of the lower Siret river are affected by anthropogenic activities as well as by seasonal variations of water flow and temperature. The study shows the complexity of these correlations and the necessity of a global, multi-parametric monitoring in order to establish the real impact and the relative contribution of natural and anthropogenic causes.
