Beside above, what is a swale in landscaping?

Swales can be part of an area'snaturallandscaping, or they can be created to help ensureproperdrainage, minimize runoff or capture storm water. In simpleterms,they are generally shallow ditches that have gentlyslopingsides.

How do you divert water runoff?

  1. BUILD A BERM, a small hill covered with grass or otherplantsthat will divert runoff around what you want to protect.
  3. GRADE BROAD SURFACES to direct runoff away from houses,sheds,barns, and patios.
  4. INTERCEPT THE WATER by using a swale, a shallow ditchwithgently sloping sides.

How do drainage swales work?

Swales follow the contours around the base ofanatural or created slope, redirecting storm water andfilteringrunoff as it sinks into the soil, instead of keeping it inoneplace, like a rain garden.
