RIVERBANK STABILITY ANALYSIS. II: APPLICATIONS.

Bank retreat occurs by a combination of lateral erosion by the flow and mass failure under gravity. A new analysis of bank erosion and failure is developed, using a critical shear-stress concept to account for lateral erosion and a slope stability criterion for mass failure. In this paper, we apply the analysis to two problems of bank retreat often encountered by practicing engineers dealing with alluvial channels. The first application is to the prediction of degradation downstream of a dam for the case in which bed lowering causes bank instability. The second application is to the modeling of flow in channel bends and the prediction of the equilibrium cross section.
