| Abstract: | A special testing flume is used to study the sediment incipient motion in circulating flow. The experimental phenomena show that the law of sediment incipient motion in circulating flow is different from that in straight channel flow. The property of sediment incipient motion in circulating flow has been analysed. Based on the theoretical derivation, a formula for calculating velocity of sediment incipient motion has been proposed, and a good agreement between the calculated and experimental data is obtained. |
