| Abstract: | As the confluence of different channels is common in the natural rivers and hydraulic pro- jects, the study of its flow and sediment characteristics are very important on flood control, navigation and ecosystem. In this paper, the researches on characteristics of water surface condition, spiral flow, flow structure, energy loss and sediment transport at the confluence of open channels in the past 70 years are reviewed, and the development prospect is also discussed. |
