When the temperature of a river rises, the water particles move faster, which causes the water to heat up. This makes the water expand, although only to a very small extent. In addition, if a river is fast flowing some of the water may begin to evaporate, causing a mist over the surface of the river. The temperature rise of a river can have a number of effects; these are explained in the points below.
- Marine wildlife disaster
- The impact on other types of wildlife
- The local economy
