基于阻力规律的床面形态判别方法
Discrimination method of bed forms based on the law of resistance
摘要
Abstract
The variation of the bed forms exerts vital influence on river evolution. Predicting possible bed forms grounded on the conditions of flow and sediment transportation has always been a practical concern in channel regulation and sediment research. The law of resistance is the reflection of flow, bed forms and other features. Therefore, analyzing the law of resistance could be used to distinguish the boundary between different bed forms. Based on the law of resistance and the existing flume experimental data,two dimension⁃less bed form parameters, as well as the boundaries between various bed forms are proposed. Different bed forms are demonstrated in the distribution diagram, and the boundary equations between different bed forms in both high and low flow regimes are also obtained. The equations can be used to identify and forecast bed forms,and which could guide the channel regulation.关键词
