This article is about installations designed to capture and convey surface runoff along a vegetated channel, whilst also promoting infiltration.
For underground conveyance which promotes infiltration, see Exfiltration trenches.
For conveyance along planted channels, on both surface and underground, see Bioswales.
Overview[edit]
The fundamental components of an enhanced grassed swale are:
- Graded channel
- Resilient turf grass
- Check dams, to facilitate short tern ponding
Additional components may include:
- Amended soil, to increase infiltration to soils below
- Impermeable membrane, to prevent infiltration to soils below
- Turf reinforcement, to prevent scour
