摘要
针对如何在宽浅多变、河床冲淤变化较大的河流确定泵站取水口水位这个问题，利用水位流量关系，抓住河床冲淤变化影响最低水位这个主要矛盾，根据测淤断面多年的淤积测量资料，求得一定水面宽度的主槽平均河底高程，与相应的河道水深叠加后以确定取水口水位。
According to the
lowest water level affected by the Change of erodible channel, using the discharge curve to select
the location of inlet of pumping station. The water level at the inlet is designed on the basis of
analysis of the many years survey data at sediment datum and the average bottom level of the
main channel.
