Wetlands play a crucial role in flood control as they act as natural sponges that absorb and store excess water during heavy rainfall or flooding events. This helps to reduce the peak flow of water, slowing down the movement of water and decreasing the likelihood of downstream flooding. Wetlands also help to recharge groundwater supplies and release water slowly over time, which further contributes to flood mitigation efforts. By preserving and restoring wetlands, we can effectively manage and reduce the impacts of floods on communities and ecosystems.
