Similar to [[swales]], biofilters, [[enhanced swales|enhanced grassed swales]], and [[bioretention]], bioswales are long [[vegetation|vegetated]] open channels trapezoidal channels which are designed to treat, convey, infiltrate, and attenuate incoming stormwater runoff. Similar to roadside ditches, they are predominately used to help direct large stormwater flow volume from a large catchment area (i.e., road, parking lot, property) to a connected discharge point (i.e. [[overflow|overflow outlet]] connected to the municipal storm sewer system, or to another LID BMP). Bioswales with the optional use of [[check dams]] can also slow and clean suspended sediments along the practice's sloped channel, while also allowing water to infiltrate through the system to an associated [[underdrain]] system below.

Bioswale [[vegetation]] is generally lawn [[grasses]], but there are numerous variations that include: [[perennials]], [[shrubs]], small [[trees]] and various plants or [[river rock] that allow the practice to still effectively infiltrate and convey incoming stormwater runoff.
