Vegetated Waterways

Vegetated waterways are built to protect soil against the erosive forces of concentrated runoff from sloping lands. By collecting and concentrating overland flow, waterways absorb the destructive energy which causes channel erosion and gully formation..

Waterways can have cross sections in parabolic, trapezoidal, or triangular form, depending on the functional requirements. Several of these requirements are climate, channel capacity, and desired flow velocity.

Grass linings should be hardy, dense - growing perennials adapted to the geographical region and soil. The grass should be cut periodically, fertilized as needed, and not subjected to prolonged traffic by either livestock or vehicles.
