洪水涨落过程,由于洪水波传播所引起的附加比降的不同,使断面上的流量与同级水位稳定时流量相比产生有规律的增大或减小,反映在水位流量关系上,曲线呈逆时针的绳套曲线。要定好这样的曲线,需要有许多实测点据。若能在保证精度的前提下,对绳套线进行单值处理,求出相应的稳定曲线,减少测流次数,减轻繁重的流量施测任务,以适合站队结合的需要,这就是本文的出发点。近年来各地都
Flood fluctuation process, due to the flood wave propagation caused by the additional ratio of different, so that the cross-section flow and the same level when the steady flow of water than a regular increase or decrease, reflected in the water flow relationship, the curve Was anti-clockwise rope cover curve. To set such a curve, you need to have a lot of measured data. If we can guarantee the accuracy of the premise, the single-value processing of the sheathed line to find the corresponding stability curve, reducing the number of flow measurement, reducing heavy flow measurement mission to suit the needs of the station team, which is the starting point of this article . In recent years all over
