It will just accumulate more water in the river but, if the runoff water becomes toxic due to nearby factories or power plants then it can damage that ecosystem.
The river becomes 'polluted'.
runoff can pollute a river or stream because when the water flows over the ground, it could pick up some trash or garbage on the ground, and the garbage could flow with the runoff. Then when the runoff enters a stream, lake, or ocean, the garbage will flow into the water, causing pollution.
....runoff is when water overflows from a river so if theres too much rain it could overflow the river and create a runoff
Runoff is extra water that came from anoter body of water, usually after a big rainstorm. If there is enough water going down hill, it can form a river.
it will increase because the more water.... the faster.... its just a true fact!! You Know??
I believe that it is called a runoff.
