Mapping of water erosion forms in the urban district of attecoube (abidjan, cote d’ivoire)

The current work aims to map the different forms of erosion which are expressed in the district of Attecoube. From georeferenced aerial photographs and based on the concepts of texture and structure, the different forms of erosion were discriminated on the screen. Many field visits, with tablets, GPS and tape measure (for measurements) allowed checking and adjusting the interpretations made on screen. These high-tech devices were also used for capturing images. Then, we superimposed the erosion forms map at the slopes map of the study area. Three main forms of erosion were revealed: - diffuse erosion covers 14,32% of the study area; - gully erosion which manifest itself on every slope range, covers 66.39% of the Attecoube district; - mass wasting localised, cover only 06.82% of the study area.
