一、陕县水文站自1955年12月起,按规范规定的测速垂线数目的要求进行测流,直至1956年3月20日止,共施测了20次流量,并进行了分析。根据经验,陕县的河道是稳定的,也就是陕县的河道没有发生过变迁,但是,陕县的断面是有冲淤变化的。从多次的资料证明,陕县的断面在每一个洪峰过程中有以下的规律(陕县的断面形式如图一)洪水起涨到峰顶,主槽冲深,并往北移,北部边槽也
First, Shanxian Hydrological Station Since December 1955, according to the requirements of the standard number of vertical velocities measured flow measurement, until March 20, 1956, a total of 20 measured and measured the flow and conducted an analysis. According to experience, the river in Shanxian is stable, that is, the river in Shanxian has not changed. However, the section of Shanxian is changing with erosion and deposition. From many times of data we can see that the section of Shanxian has the following rules in every flood peak (the section of Shanxian is shown in Fig. 1). The flood rises to the top of the peak, the main channel goes deep and moves north, while the northern side Slot also
