代表垂线法在中小河流流量测验中的应用与分析

Application of representative vertical method in flow measurement on medium and small rivers

传统旋桨式流速仪操作简单,性能可靠,适用性强,在水文应急测验方面有着不可替代的优势。以星丰(三)站为例,探讨旋桨式流速仪结合代表垂线法测流方案在山溪性中小河流洪水期的适用性。分析结果表明,代表垂线法操作简便,测量精度高,适用于山溪性中小河流的洪水期流量测验。

Traditional propeller type flow velocity meter permits simple operation with reliable performance and good adaptability, and has irreplaceable advantages in emergency measuring. Taking Xingfeng Hydrological III Station as example, the author discussed the adaptability of propeller type flow velocity meter combined with representative vertical method in flood-period flow measurement on medium and small rivers of mountain stream characteristics.The results of analysis demonstrate the representative vertical method is applicable with high measurement accuracy and permits convenient measuring.
