Equilibrium Geometry of Channels with Cohesive Banks

Document Type: Proceeding Paper

Part of: Hydraulic Engineering

Abstract:

An optimization model is used to assess the stability of gravel-bed rivers with cohesive channel banks and to determine the effect of the bank stability on the equilibrium hydraulic geometry. The results indicate that the two principal erosion mechanisms, namely mass failure, and fluvial erosion at the toe of the bank, exert a controlling influence on the channel geometry. Furthermore for a particular channel only one of the erosion mechanisms is actively constraining the channel. Recognition of the controlling bank erosion process is necessary for the assessment of bank and channel stability, and for predictions of future channel response.
