The coastal unit between the Vridi canal and the Port-Bouët lighthouse, south of Abidjan, is the subject of this study. It was followed over two periods (November 2015 and October 2016) following the eviction, downstream, on the waterfront of several precarious neighborhoods (Derrière Wharf, Adjouffou, Gonzagueville, ...). This study uses GPS data coupled with worksite level data to reconstruct the morphology of the study area as well as its description and evolution from different beach profiles. The acquired data is processed from the software "MapSource", "Excel" and "Surfer". For each profile, the different morphological units of the range were determined from classical terminology. In general, all the recorded profiles have a straight or concave shape. This is characteristic of an unbalanced beach profile with sand start and erosion. The length of the profiles varies between 16 m and 53 m. The elevation difference is between 4 m and 7 m with a variable slope (2.86 ° to 14.03 °). They are reflexive beaches with a strong erosional tendency.
