So when it rains they are easily washed into the groundwater and runoff water.

所以当下雨的时候，它们很容易被冲到地下水以及径水中。

In mountainous terrain, the combination of gravity plus the easy runoff can lead to catastrophic flooding when all of that water is funneled into rivers, creeks and even the valleys.

在山区，在积水注入河、小溪甚至是域以后，重力和径的联作用会引发灾难性洪水。

Experts say one potential cause is agricultural runoff.

专家表示，其中一个潜在原因就是农业径。

They had reduced harmful water runoff to safeguard the health of the reef.

For a while, small rivers and irrigation runoff fed the lake.

The scientists said this was because of river run-off.

科学家表示，这是河径造成的。

Water absorption is greatly reduced, consequently runoff is increased, resulting in accelerated erosion rates.

吸水量大大减少, 因此径增加, 导致侵蚀速度加快。

But experts say heavy rainfall is causing runoff pollutants from all over the area to reach the bay. They say this could lead to large dead zones in the waterway.

但专家表示，暴雨导致该地区的径污染物从四面八方涌入海湾。他们指出，这可能导致航道出现大面积的死亡地带。

This erosion is a slow and continuous process that leads to the formation of salt and other minerals, which then carried to the Dead Sea through runoff from the rocky regions.

这种侵蚀是一个缓慢而持续的过程，导致盐和其他矿物质的形成，然后这些矿物质通过径从岩石地区带到死海。

Their ecosystems suffer from coastal run-off, whether sewage or waste from farms, as well as the sediment dumped from beach-front building sites.

它们的生态系统受到沿海径的影响，无论是来自农场的污水或废物，还是来自海滨建筑工地的沉积物。

It can, the company claims, reduce the airborne drift of chemicals by up to 87% and chemical run-off by up to 93%.

该公司声称，它可以将化学物质在空气中的漂移减少高达87%，将化学物质径减少高达93%。

Rockstrom said the Earth's water went from being safe to being " out-of-bounds." The scientists said this was because of river run-off.

罗克斯特罗姆说，地球上的水从全变成了“超出界限”。科学家说，这是河径造成的。

The plume of salty runoff stayed intact much farther out than models predicted, rather than easily blending with closer seawater.

含盐径羽比模型所预测的要完整得多，不会轻易与较近海水相混。

An estimated 100,000 to one million fish suffocated because the river levels were too low to flush out farm runoff.

据估计，河水水位过低，无法注入农田径，致10万到100万条鱼因窒息而死亡。

Scientists say nutrient pollution runoff from farms is the main problem.

科学家表示，来自农场的养分污染径是主要问题。

It's because of the spray and because of some run-off, so we are literally in a bit of a bog.

径，这里已经水漫金山，我们真的是身陷泥潭了。
