Influences of Anthropogenic Pressures on the Morphology and Hydrochemical Parameters of Bingerville Bay (Côte D'Ivoire)

Bays are aquatic environments in which the depth tends to decrease due to numerous sediment deposits. Anthropogenic activity has a negative impact through pollution and changes to the morphology of this environment. This study was carried out in Bingerville Bay, in order to study the morphology and hydrology through hydrochemical parameters. The morphological study of the Bingerville estuary was carried out in order to characterise the morphology of the bottom of the bay using bathymetric maps (2D, 3D, slope and physiographic maps). These maps will be interpreted to establish a qualitative and quantitative study of the different channels obtained : U-shaped channels (transport and deposition event), V-shaped channels (erosion and transport event) and intermediate channels. A study of the bathymetric maps reveals a depression that is the result of human activity (dredging and development of the bay). They also show the deterioration in water properties due to changes in hydrochemical parameters compared with WHO standards. This variation in parameters is also linked to morphological changes in Bingerville Bay as a result of human pressures.
