黄河的泥沙问题是比较突出的,从其内容与范围来说,一般可分为库区泥沙、坝前泥沙及下游泥沙三类。当泥沙(包括水草等动物)淤到枢纽前时,将给电站、大坝的泄水建筑带来危害,如因水轮机和泄水建筑物的磨损、拦污栅被水草淤堵等事故而影响发电。因此在进行河流开发、工程设计及运行时,必须认真考虑泥沙问题,根据其问题的轻重予以分别
The Yellow River sediment problem is more prominent, from its content and scope, the general can be divided into reservoir sediment, dam sediment and downstream sediment three categories. When sediment (including plants such as aquatic weeds) is silted to the front of the hub, it will bring harm to the drainage structures of power stations and dams. For example, due to the abrasion of hydraulic turbines and drainage structures, Affect power generation. Therefore, river development, engineering design and operation, we must seriously consider the issue of sediment, according to the severity of their problems be divided
