Swale
A Swale (also Swale Drain) is a shallow channel lined with vegetation, usually grass, used to convey stormwater.
The objective of a swale is to minimise the use of piped stormwater draingage system, in accordance with Water Sensitive Urban Design. It also functions to slow down stormwater flows and remove coarse to medium sediments.
A swale is not suitable for very steep (>4%) or flat (<1%) terrain.
