Physico-chemical Composition of Urban Wet Weather Discharges in Seybous Watershed (north Eastern Algeria)

Seybous Watershed is one of the largest basins in Algeria. It is characterized by a large urban and industrial activity presented on both banks of the river and tributaries Seybous. It daily receives discharged without treatment. This work provides an overview of the quality of urban wet weather discharges; this study is based on several morphological parameters Hydrometeorological basin. During the year 2012, two samples were performed ( in August and September). These have worn on urban waste and the waters of Seybous Wadi. The analysis results indicate that urban waste are characterized by high pollutant load varies with the rain and the influence of these releases is visually along the rivers and waters of the different stations are between the classes of poor quality very bad.
