Abstract

Until now all research work related to river alluvial process consideres the river system as a classical dynamic system, but this paper views alluvial river process as a nonlinear dynamics system. As a nonlinear system some brand new phenomena are explored such as chaos, pattern evolution, butterfly effect, strange attractors. Based on experimental results and real river data, the stability and predictability of river alluvial process are discussed. The conclusion shows that sometimes the alluvial river system is unstable and unpredictable inherently somehow.

Keywords: Nonlinear dynamics system, chaos, butterfly effect, strange attractors
