| 摘 要： | 1 INTRODUCTION It is well known that the river channel patterns are determined by long-term water-sediment conditions. However, quantitative expressions for river channel patterns and their fluvial processes still remain not clear. Existing theories in this aspects, such as geomophological theory, theory of maximum energy consuming rate, stability theory, theory of probability, and statistic analysis, are developed based on certain simplified assumptions and can not be successfully used t…

| Abstract: | In normal fluvial processes the river channel is determined by river flows while the movement of river flows is contained by river channels. The relationship between the river morphology and its bend curvature shows that rivers with large bend curvatures always have narrow and deep channels and those with shallow and wide channels are always straight. The plan form of a river reaches is determined by the cross-sectional morphology. A meandering river reach may be developed under various water-sediment conditions as long as the narrow and deep channels are formed. |
