Vegetated conveyances are channels or swales that are created and include vegetation to decrease the speed of water and increase water infiltration.
Vegetated conveyances can provide opportunities for runoff treatment, and groundwater discharge. Also, they can replace conventional storm sewer systems in small drainage areas.

Considerations
Vegetated channels and swales should be constructed only in areas with sufficient sunlight to adequately maintain vegetation.
The channels must also be able to drain and dry out between storm events.
As an alternative, the channel could be planted with ground covers that tolerate frequent short-duration flooding.
