The calculation of the transverse transport of sediments with secondary flow in river bends is very important to the investigation of the transverse change of channel.
河湾副流的横向输沙计算，对于研究河道横向演变及其变形规律具有很大的实际意义。
2
There is improvement as compared with the method of total flow which only gives the average velocity of transverse profile of open channel.
较总流量分析法，仅能给出明渠断面平均流速有所改进。
3
The analysis method of flow field not only can show the discharge in open channel, but also the velocity distribution of its transverse profile.
