Learn more about the benefits of grassed waterways and how they work.
Grassed waterways, when properly constructed, help collect water and convey it off the landscape without causing soil erosion, thereby improving water quality.
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.
