Bend theory of river meanders. Part 1. Linear development

Research output: Contribution to journalArticlepeer-review


Instability of the alternate-bar type in straight channels has long been identified as the cause of fluvial meandering. The condition of inerodible sidewalls, however, does not allow a meandering channel to develop. Herein a stability analysis of a sinuous channel with erodible banks allows for delineation of a ‘bend' instability that does not occur in straight channels, and differs from the alternate-bar instability.
