Study regarding the dispersion of water quality indicators in the Danube river

Abstract

The Danube River is of particular importance for countries whose territories it crosses, both economically but for its impressive biodiversity, too. Thus, it is important to know the distribution of pollutants in certain areas of interest, in order to mitigate their expansion and to decontaminate the pollution prone zones. In this study, was assessed an accidental pollution scenario by using the numerical simulation program Delft3D. It was analysed the dispersion of water quality indicators in the Danube. Hence, it was intended to estimate the river area dimensions that would be polluted in the context of toxic substances discharges and to evaluate the river pollution level on the affected section by the toxic wave. The use of this program allows the tracking in time and space of the pollutants concentration, providing information on the effects the pollutants discharges may have on the Danube River, depending on the hydro- morphological conditions.
