Abstract

 Like many other cities in Senegal, Dakar is facing recurrent floods with associated environmental problems including permanently flooded areas. The paper discusses the topographic setting of Dakar and the geology of the horsts and grabens. It highlights the apparent lack of planning and urban management that took place when significant numbers of the population moved into the towns during periods of intense drought. It emphasises that the problems of Dakar should be considered by planners in other similar areas in an attempt to reduce the impact of flooding.

Résumé

Comme de nombreuses villes du Sénégal, Dakar doit faire face à des inondations répétées avec les problèmes environnementaux associés, incluant l'existence de zones inondées de façon permanente. L'article présente le contexte topographique de Dakar et le cadre géologique en horsts et grabens. Il met en lumière l'apparent manque de planification dans l'organisation de l'espace et l'aménagement urbain qui a prévalu lorsque des mouvements importants de populations vers les villes ont suivi les périodes d'intense sécheresse. L'article met l'accent sur l'analogie des problèmes de Dakar avec ceux d'autres centres urbains que des planificateurs devraient prendre en considération afin de tenter de réduire l'impact des inondations.
