When trying to reduce the possibility of severe gully erosion,
grassed waterways provide a helpful solution. They force storm
runoff water to flow down the center of an established grass
strip and can carry very large quantities of storm water across
a field without erosion. Grass waterways are also used as
filters to remove sediment, but may sometimes loose their
effectiveness when too much sediment builds up in the
waterways. To prevent this, it is important that crop
residues, buffer strips, and other erosion control practices
and structures be used along with grass waterways for maximum
effectiveness.
