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...
