摘要
The flow and roughness characteristics of fluvial rivers vary in accordance with the properties of the bed configurations. In field rivers, sand waves with different characteristic lengths are often formed simultaneously. This kind of bed configurations can hardly be observed in the flume experiments. In the present research, the bed configurations are classified into three types according to the type of bar and the characteristics of the resistance to flow are analysed in relation to the type of bar.
