Swales are shallow, typically grassy channels designed to manage water runoff and improve drainage. They help to direct rainwater away from paved surfaces, allowing it to soak into the ground instead of causing erosion or flooding. Swales can be found in various landscapes, including urban areas, parks, and agricultural fields. These features are often part of sustainable landscaping practices, promoting natural water management. By using swales, communities can reduce the need for stormwater systems and enhance local ecosystems. They also support biodiversity by providing habitats for various plants and animals while improving water quality.
