Water Quality Benefits of Grass Swales in Managing Highway Runoff
2006
Proceedings of the Water Environment Federation
Grass swales are a vegetated stormwater management technology that can remove surface runoff contamination through sedimentation, filtration by the grass blades, infiltration to the soil, and likely some biological processes. Two full-scale grass swales in the median of a four-lane highway were monitored during 18 storm events to characterize the overall performance of grass swales as a stormwater management technology and to evaluate the effect of the shallow-sloped grass pre-treatment area
