弯曲型河道挟沙水流运动规律研究进展

Development of Sediment-laden Flow Movement Law Research in the River Bend

弯道水流 (包括挟沙水流 )运动规律的研究 ,在水利工程学的许多领域中 ,占有重要的位置。本文着重对弯道水流水面横比降、横向环流、纵向垂线平均流速分布规律及弯道输沙特性研究进展进行了阐述分析 ,以便为生产科研方面服务。

The study on the sediment\|laden flow movement law in the river bend is very important in many fields of hydraulic engineering. This paper discusses the research development of such laws as the lateral slope of the water surface, secondary circulation flow, average velocity along vertical line, distribution of the main streamline and sediment transport characteristics in the river bend.
