What human activities reduce the land’s ability to absorb runoff?
River Basin Scavenge
| Question | Answer |
|---|---|
| Why are more humans vulnerable to flooding? | -alternation of land around rivers changing the path of water -wetlands have been filled -streams have been straightned , paved, and developed – accelerated urban development and land disturbance reducing the land’s ability to absorb runoff |
What do river basins do?
Both river basins and watersheds are areas of land that drain to a particular water body, such as a lake, stream, river or estuary. In a river basin, all the water drains to a large river. The term watershed is used to describe a smaller area of land that drains to a smaller stream, lake or wetland.

Why is river basins important?
Drainage basins are important in ecology. As water flows over the ground and along rivers it can pick up nutrients, sediment, and pollutants. With the water, they are transported towards the outlet of the basin, and can affect the ecological processes along the way as well as in the receiving water source.
How can we protect our river basins from pollution?
What You Can do to Help
- Conserve water every day.
- Don’t pour toxic household chemicals down the drain; take them to a hazardous waste center.
- Use hardy plants that require little or no watering, fertilizers or pesticides in your yard.
- Do not over apply fertilizers.
How can activities on land relate to the health of aquatic ecosystems?
Paved roads, parking lots and other impervious surfaces can exacerbate the flow of pollution into the water. Because these surfaces don’t absorb water, they make it easier for nutrients and other harmful chemicals to run off into streams during rainstorms.
Why are basins important?
Basins are vital to human existence, since they provide clean water for drinking; water for growing food; and water to nourish plant life, which provides the oxygen people breathe. Historically, basins were also an important factor in determining geopolitical borders.
