A new method is proposed to estimate annual amount of bed load, in which the typical hydrological year of discharge series is selected based on the relationship between the bed load rate and hydraulic factors.
基于推移质输沙率与水流动力条件之间的关系，提出了一种计算年平均推移质输沙量时，代表性水流动力条件的选择方法，同时将断面分为若干子断面进行计算，可以解决推移质沿断面不均匀输移的计算困难，计算过程中还考虑了推移质级配的逐时变化。
A hydraulic-operated automatic gate is one that works automatically with the help of water pressure and impulsive force, and under certain water level or water level difference, it will open or close or keep balanced at a certain angle.
