How
it works
A natural drainage way is graded and shaped
to form a smooth, bowl-shaped channel. This area is seeded to sod-forming
grasses. Runoff water that flows down the drainage way flows across the
grass rather than tearing away soil and forming a larger gully. An outlet
is often installed at the base of the drainageway to stabilize the waterway
and prevent a new gully from forming.
How it helps
Grass cover protects the drainage way
from gully erosion.
Vegetation may act as a filter,
absorbing some of the chemicals and nutrients in runoff water.
Vegetation provides cover for
small birds and animals.
