摘要
基于ADCP反向散射信号可以推算悬移质含沙量。自2011年9月到2013年12月,通过选取长江下游大通水文站作为实验点,采用传统法和ADCP法在同一断面测量了悬移质含沙量,两种方法测量的结果相关系数达到了0.98。实验研究表明:ADCP法测沙可以解决水文测站悬移质含沙量的自动化测量问题。
Based on the ADCP backscatter signal, the suspended sediment concentration can be estimated. From September 2011 to December 2013, by selecting the Datong hydrological station in the lower reaches of the Yangtze River as the experimental point, the suspended sediment sediment concentration was measured in the same section by the traditional method and the ADCP method. The correlation coefficient of the two methods was reached 0.98. Experimental studies show that the ADCP method can solve the problem of automatic measurement of suspended sediment concentration in hydrological stations.
