The formulary structure about transverse mixing coefficient of rivers has been studied at the laboratory model of straight rectangular open channel.
本文在实验室矩形平直明渠内，对横向混合系数的公式结构进行了探讨。

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。

There is improvement as compared with the method of total flow which only gives the average velocity of transverse profile of open channel.
