1·The ice blocks up the river, making the upstream water unable to flow.
冰把河道堵住了，上游的水流不下来。
2·Downstream of the upstream water too much, cause water shortage, block;
上游未经处理排出的废污水，造成下游河道污染；
3·Reporters across the Silver Bridge to later see in the upstream water is indeed very clear.
记者在跨过银溪桥后见到，上游的水的确很清。
4·With the upstream water level reducing and the downstream water level increasing, the highest tangent velocity also moving to the pipe center.
随上游水位的降低及下游水位的升高，切向流速最大值点也不断向管中心一侧移动。
5·The bigger the downstream water level, the outstanding of variation degree of axial velocity along radius distribution when upstream water level is same.
下游水位越高，变化相同的上游水位时，轴向流速沿径向分布的变化程度越大。
6·Sustained drought and insatiable upstream water demand have drained Lake Mead to the point that experts are predicting it may soon be shallow enough to be in deep trouble.
持续的干旱和上流不断增加的水需求已经使米德湖快要陷入专家预测中可能造成麻烦的低点。
7·Moreover, downstream factories and drinking water companies will benefit from the upstream water quality improvement measures, too and also from greater flood protection.
另外，下游地区工厂和饮用水公司也可能会从上游旨在提高水质量的措施和更大范围的防洪工作中受益。
8·Israel has extracted about 65% of the water upstream of the Jordan River.
以色列提开采了约旦河上游约65%的水源。
9·Once a construction project starts upstream, it requires water compensation downstream.
一旦上游开始基建项目，下游就需要对用水进行补偿。
10·The upstream countries point to Egypt's own wasteful practices, saying the 75 percent of Egypt's water is used for agriculture, most of it wasted by inefficient, old-fashioned practices.
而上游国家则指责埃及自身的挥霍习惯，认为埃及75%的水资源都用于农业，其中大部分均被低效而过时的耕种模式所浪费。
