Abstract

Using the middle Hanjiang River as an example, this paper deals with the development of mid-channel bars in a braided river, as controlled by channel boundary conditions, runoff and sediment load, as well as reservoir construction. Relations have been established between indices describing the mid-channel bars and the controlling variables, such as the channel width, the percentage silt-clay content in the channel boundary and the energy expenditure of flowing water. Bank erosion exerts a marked influence on the development of mid-channel bars after reservoir construction. A descriptive model showing the complex response has been established
