Urban lake system eutrophication – A case study

Abstract

The dynamic eutrophication process study of Yamoussoukro lake system in Côte d'Ivoire was carried out from February 1997 to January 1998. It appeared that this phenomenon is related to the nutriments that are phosphorus mainly and nitrogen. It was shown that the fluctuations of these nutriments depend on the climatic phenomena, the rural activities such as the bush fires and the urban activities including the domestic rejections. The total phosphorus average optimal value obtained at the beginning of the rainy season was of 0,18 mg/L. That also corresponded to the increase of watery plants quantity.
