FLOOD RISK REDUCTION IN ABOBO (Abidjan)

This study mainly developed a mapping method and assessed the risk of flooding in urban areas adapted to the context of anarchic urbanization and poorly controlled sanitation in the municipality of Abobo (Abidjan Côte d''Ivoire). It was broken down into three specific objectives: First the identification of hazard and vulnerability factors at the origin of flooding; Second the mapping of flood risk areas based on Saaty''s AHP Multicriteria Analysis; Third the modeling of the rainfall runoff system at the scale of the Sagbé-Anonkoi Kouté watershed in order to establish a projection of flooding over the periods of 5 25 50 and 100 years with a view to assisting decision-makers in considering anticipatory decisions.
