How do wetlands help rivers slow floods?
Quick Answer
Wetlands act like natural sponges by storing water temporarily and releasing it slowly. This reduces flood peaks and helps protect downstream areas.
The Full Story
Wetlands absorb and hold excess water during heavy rain, snowmelt, or river floods. Because their soils and plants slow the movement of water, they reduce the speed and height of flood waves. They also trap sediment and filter pollutants before water reaches rivers and lakes. For this reason, wetlands are often called natural flood defenses.
