Where the water goes
- When rain falls on a hillside, it flows downhill and collects.
- All the rain in one area ends up in the same river.
- That whole area of draining land is a watershed.
- Watersheds connect everyone who shares the same water.
水往哪里去
- 当雨落在山坡上,它顺山而下并汇集。
- 一个区域里所有的雨最终都进入同一条河。
- 那整片排水的土地就是一个流域。
- 流域把共享同样的水的每个人连接起来。
What a watershed is
- A watershed 流域 is all the land that drains its water to a single river or lake.
- Rain falling anywhere in it flows to the same outlet.
- Big rivers have huge watersheds made of many smaller ones.
- Every point on land belongs to some watershed.
什么是流域
- 一个流域(watershed)是把它的水排到单一河流或湖泊的所有土地。
- 落在它里面任何地方的雨都流到同一个出口。
- 大河有由许多更小流域组成的巨大流域。
- 陆地上每一个点都属于某个流域。
A watershed is… · 一个流域是……
A watershed is the whole area of land that drains its water to one common outlet. · 一个流域是把它的水排到一个共同出口的整片土地。
The divide
- Two neighbouring watersheds are separated by high ground.
- This high boundary is called a divide 分水岭.
- Rain on one side of the divide flows to one river; rain on the other side flows to another.
- A ridge or mountain crest often marks the divide.
分水岭
- 两个相邻的流域被高地分隔。
- 这个高的边界叫做分水岭(divide)。
- 分水岭一侧的雨流向一条河;另一侧的雨流向另一条。
- 一道山脊或山顶常常标出分水岭。
The high ground separating two watersheds is called a… · 分隔两个流域的高地叫做……
A divide (usually a ridge) separates the land that drains into different watersheds. · 一个分水岭(通常是一道山脊)分隔排水到不同流域的土地。
Water flowing over the land surface into rivers is called . · 在陆地表面流入河流的水叫做。
Runoff is rain that flows over the surface and collects in the watershed's river. · 径流是在表面流动、汇集到流域河流中的雨。
Everything is connected
- Rain becomes runoff 径流 that carries soil, nutrients, and pollutants along.
- Because the whole watershed drains to one place, actions upstream affect everyone downstream.
- A factory or farm upstream sends its pollution down to those below.
- This is why protecting a watershed protects everyone who uses its water.
一切都相连
- 雨变成径流(runoff),沿途携带土壤、养分和污染物。
- 因为整个流域排到一个地方,上游的行动影响下游的每个人。
- 上游的一座工厂或农场把它的污染送到下面的人那里。
- 这就是为什么保护一个流域就保护每个使用它水的人。
Inside or outside the watershed? · 在流域内还是外?
Sort each idea by whether it correctly describes a watershed. · 按照每个说法是否正确描述一个流域,给它们分类。
Pollution added upstream in a watershed can travel downstream to everyone below. · 在流域上游加入的污染能顺流而下,到达下面的每个人。
A watershed connects everything by water, so upstream pollution flows down to those below. · 流域用水把一切连接起来,所以上游的污染流到下面的人那里。
Select all · 所有 true statements about watersheds. · 选出关于流域的所有正确说法。
How the land is used strongly affects the watershed's water. The other three are correct. · 土地如何被利用强烈影响流域的水。其余三条正确。
In a watershed, upstream and downstream are linked. Pollution added anywhere upstream — fertiliser, sewage, waste — flows down to every community below. You cannot pollute "your part" of a river without affecting everyone downstream who shares the same watershed.
在一个流域里,上游和下游是相连的。在上游任何地方加入的污染——化肥、污水、废物——都流到下面的每个社区。你无法在不影响共享同一流域的每个下游者的情况下污染河流"你的那部分"。
A shared river:
- A town dumps waste into a river near the top of a watershed.
- The waste flows downstream, past farms, cities, and wildlife.
- Every community below is affected — which is why watersheds are often managed together, not town by town.
一条共享的河:
- 一个镇把废物倒进流域顶部附近的一条河。
- 废物顺流而下,经过农场、城市和野生动物。
- 下面的每个社区都受影响——这就是为什么流域常常被一起管理,而不是一个镇一个镇地。
A watershed is all the land that drains its water to a single river or lake, separated from its neighbours by a divide. Rain becomes runoff that carries materials downstream, so upstream actions affect everyone below. Protecting the whole watershed protects everyone who shares its water.
一个流域是把它的水排到单一河流或湖泊的所有土地,由一个分水岭与它的邻居分隔。雨变成把物质带到下游的径流,所以上游的行动影响下面的每个人。保护整个流域就保护每个共享它水的人。
