What is a swale?

A swale is a shallow, elongated ditch or channel designed to manage water runoff. It's a key feature in permaculture and sustainable landscaping. Swales are designed to slow down and infiltrate water into the soil, reducing erosion, replenishing groundwater, and filtering pollutants.

Here are some key aspects of swales:

• Purpose: Primarily for water management, but also used to create microclimates, improve soil health, and increase biodiversity.

• Design: Typically follows the contour of the land, with a gentle slope. The dimensions vary depending on the specific needs and site conditions. A crucial aspect of Swale%20Design is ensuring proper drainage to prevent waterlogging.

• Construction: Involves excavating the channel, often with a berm (raised bank) on the downhill side to further slow and direct water.

• Benefits: Include reduced flooding, increased water infiltration, improved soil fertility, habitat creation, and aesthetic appeal. Swales can also contribute to Erosion%20Control by slowing water flow.

• Types: Variations exist, such as vegetated swales, dry swales, and bioswales, each adapted to different purposes and environments. Bioswales are specifically designed with a dense plant community to filter pollutants.
