Wetlands play a crucial role in flood control by acting as natural sponges that absorb and store excess water during heavy rainfalls or flooding events. They help to slow down the flow of water, reducing the risk of flash floods and providing a buffer against extreme weather events. Wetlands also help to regulate water levels in rivers and streams, reducing the likelihood of downstream flooding. Additionally, wetlands provide habitat for diverse plant and animal species that contribute to the overall health and resilience of ecosystems.
