Abstract: Erosional processes along Ekole Creek bank between Yenaka and Ayama in the Niger Delta have been studied and described. Bank failure is analysed and explained in terms of bank stratigraphy, water flow and the stable angle of the bank sand layer while erosional intensity variation during and after flooding ie explained in terms of hydraulic stresses on the bank during both periods. Results show that bank stability is unlikely to be attained unless the natural process of bank quasi-stabilization resulting from debris accumulation of failed bank material is aided by a permanent artificial reduction of bank slope.
