Abstract

The laboratory experiments reported here, in which the key elements were a two-level alternating discharge cycle and the addition of vegetation, demonstrate that plants alone can cause a braided river to self-organize to, and maintain, a single-thread sinuous morphology. These experiments highlight the essential role of a fluctuating discharge in the dynamics of a meandering river in which vegetation plays a key role in stabilizing the banks. Furthermore, in the presence of vegetation a fluctuating discharge can suppress braiding by providing an opportunity for vegetation to establish itself
