Etat environnemental de la lagune de Boughrara et ses alentours deux ans après les travaux d’aménagement et d’élargissement du pont d’el Kantara

Abstract

The present study aims to characterize water quality and sediment in Boughrara lagoon and its surrounding two years after the construction of new bridge. Abiotic parameters (water and sediment) are calculated in three areas with different geographical and environmental contexts. The results
have shown clear signs of improvement in terms of the ecosystem. The spatiotemporal distributions of physicochemical parameters of water indicate that the levels found below the threshold of eutrophication quite a few times but are still lower than those reported by DGPA (2000). The size analysis of surface sediments shows that the bottom of the three underwater zones explored is covered mainly by medium to fine sand rich in organic
