grassed waterway
Description
Grassed waterways are shaped constructed channels that are seeded to grass or other suitable vegetation to convey water to a stable outlet at a non-erosive velocity.
A structure is often installed at the base of the waterway to stabilize the waterway and prevent a new gully from forming.
Benefits
- Grass cover protects the waterway from gully erosion and traps sediment in runoff water.
- Vegetation can filter and absorb some of the chemicals and nutrients in runoff water.
- Vegetation provides cover for small birds and animals.
