Contribution à l'étude de la diffusion du carburant dans un cours d'eau cas d'oued Berda (w. Constantine).

Abstract

Transport and diffusion of pollutant substances in rivers result in continued degradation of water resources. Tools for prediction of transport processes must be established. Relevant to this the main objective of this study is to achieve a numerical simulation of the diffusion of pollutants in a river. For this, the river of Berda in the city of El-Khroub wilaya of Constantine is chosen it evacuates the waste water and rainwater from the Naftal complex of fuel. The results of the simulation of transport and diffusion of pollution in the river, obtained are presented in the form of curves showing the evolution of the pollutant concentration in time and space. Spatial analysis at different times shows a natural auto-I remove and progressive degradation of various pollutants into waterways.
