The instability of channel banks carries a significant economic implication because of its effect on navigation and channel commercial development. Field observation and analysis indicate that factors such as stratigraphy, local climate, bio-technical and fluvio-tidal processes act singly or in combination to generate overhangs in channel banks. The failure of channel banks with overhangs involves one of four mechanisms, namely; rotation, beam, shear, and tension failure. A mathematical basis for the discrimination of these failure mechanisms is described
