| Description |
Twenty years of research have demonstrated that the water quality of stormwater runoff can
improve after flowing in a well-vegetated channel, relatively slowly, at a depth below the
vegetation height. These channels are commonly called “biofiltration swales.” Roadside ditches
that are vegetated also may have the potential to provide the same water quality benefits as
biofiltration swales by removing pollutants. Conversely, ditches that are devoid of vegetation
are subject to erosion and could...
