Abstract

Degradation of river banks and their eventual collapse and erosion is prevalent at peak flood periods in the Niger delta area of Nigeria. Current ve locities close to 2.00 m/s at the upper reaches of its major rivers exert intensive hydrodynamic influences on the banks and levees of communities, which lead to erosion and extensive flooding episodes.

This paper examines the erodibility potentials of a study site located within the upper segment of the Ekole creek and the workability of a recently proposed engineering design solution.

Résumé

La dégradation des berges et les effondrements qui peuvent en découler se produisent dans les périodes de crues dans l’ensemble du delta du Niger, les vitesses des courants atteignant 2 mètres par seconde, et elles provoquent des inondations importantes.

Le présent article étudie l’érodabilité d’un site situé dans la partie amont de la rivière Ekole, ainsi que la faisabilité de dispositifs de protection.
