中文摘要
翻译
由于河流的水流,河流中冰盖的形成与湖泊上的冰盖形成有很大的不同。水流中的湍流导致了一种特殊类型的冰粒的形成,这种冰粒被称为脆冰,当它刚形成时,它是非常粘性的。这些脆弱的颗粒往往会相互粘在一起,粘在进水口的金属屏蔽物和架子上,粘在河床上的岩石上,甚至粘在河里的植被上。这对水电设施以及市政和工业供水来说都是一个严重的问题,因为大量的碎屑堆积可能会完全堵塞取水口,迫使工厂关闭。这些对电力系统和供水的破坏造成了巨大的社会经济代价。
英文摘要
The formation of an ice cover in a river is quite different from that on a lake because of the river's current. The turbulence in the flow causes the formation of a special kind of ice particle, known as frazil ice, which is very 'sticky' when first formed. These frazil particles tend to stick to each other, to metal screens and racks at water intakes, to rocks on the river bed, and even to vegetation in the river. This can be a serious problem for hydro-power utilities as well as for municipal and industrial water supplies, since large accumulations of frazil can completely block the intakes, forcing plants to shutdown. These disruptions to power systems and water supplies have significant socioeconomic costs.
