# River Meandering as a Self-Organization Process

@article{Stolum1996RiverMA, title={River Meandering as a Self-Organization Process}, author={H. Stolum}, journal={Science}, year={1996}, volume={271}, pages={1710 - 1713} }

Simulations of freely meandering rivers and empirical data show that the meandering process self-organizes the river morphology, or planform, into a critical state characterized by fractal geometry. The meandering process oscillates in space and time between a state in which the river planform is ordered and one in which it is chaotic. Clusters of river cutoffs tend to cause a transition between these two states and to force the system into stationary fluctuations around the critical state.

River meander behaviour and instability: a framework for analysis

- 2003

Recent empirical and theoretical work on river meanders suggests that instability is inherent. Within this context, an occurrence of multiple cut-offs could be interpreted as a clustering associated… Expand
