水位流量关系曲线绘制方法实例分析

针对水位流量关系曲线不同定线方法,以实例测站数据为基础,结合工作实际,分别采用手工方法定线、CAD软件法和水文资料整编软件三种方式进行了对比分析。从工作方式繁琐程度、工作效率和成果精度等方面,提出了三种方法的优越性和实用中的注意事项。

According to the different alignment methods of the relationship curve of water level and discharge, based on the data of an example station, combined with the working practice, the manual alignment method, CAD software method and hydrological data compilation software are adopted to make a comparative analysis. From the aspects of tedious working mode, work efficiency and result accuracy, the superiority of the three methods and the matters needing attention in practice are put forward.
