试验水槽是水力学及河流动力学开展研究的重要试验方法及设施之一。为了简化水槽试验的控制过程和提高试验精度，设计制作了国内首座可以双向运行的新型试验水槽。该水槽采用一种封闭循环的平衡式供水系统代替目前常用的供水系统，使得水槽试验的性能得以提升；同时，实现了水槽试验过程的全自动控制，包括阀门开启与关闭、泵的启动与关闭、流量的大小及水位控制等；并且可以实现水流的双向控制。

To simplify the control processes of flume experiment and improve test accuracy, we have designed a new type of experimental flume which is the first in China to be capable of bidirectional operation. A closed circulating balance system of water supply is adopted to replace the current water supply system in the flume so that the  performance of the flume is  promoted.  Moreover, complete  automatic control over the opening and closing of valve, the starting and stopping of pump, the volume of flow as well as the bidirectional flow could be realized in this flume.
