2D AND 3D MODELING OF THE MORPHOLOGY OF THE LAGOON BAY OF BEAGO (EBRIE LAGOON, CÔTE D’IVOIRE)

Abstract

The bay of Béago is located on the northern shore of the Ebrié lagoon. This bay, used for fishing, navigation and sand dredging, has also become a receptacle for macro-waste. Sand mining and the discharge of pollutants into the bay of Béago could lead to a change in its morphology. To participate in the preservation of this bay, this work aims to know its morpho-bathymetric characteristics. A bathymetric survey was carried out in the bay using a Lowrance echo sounder. The data were processed with Surfer software. West-East radials were used to identify the types of channels in the bay. The depths are between 0 and 14 m. The bottom of the bay is generally flat but is present in places by depressions and shoals. The channels are of the "intermediate" and "V" types.
