Stormwater management refers to the practices and systems designed to control the quantity and quality of water that runs off surfaces during and after rainfall. This is important because excess stormwater can lead to flooding, erosion, and water pollution. Effective management helps to protect natural water bodies and maintain the health of ecosystems. Techniques for stormwater management include retention ponds, green roofs, and permeable pavements. These methods allow water to soak into the ground, reduce runoff, and filter pollutants. By implementing these strategies, communities can better manage stormwater, ensuring safer and cleaner environments.
