Abstract/Contents: | "Runoff from roads contains numerous contaminants and can significantly increase volumes needing temporary detention. Where there are vegetated areas adjacent to the roads, it is possible to mitigate these impacts by infiltrating a portion of the runoff. This study evaluated the potential improvements in infiltration that can be achieved through tillage followed by establishment of either grass or wildflowers. Runoff was collected at highway sites either in the Piedmont or the Coastal Plain of North Carolina for a year with the existing vegetation intact in 15 plots. Five plots each were tilled and then replanted with either grass or a wildflower mix, with the remaining 5 plots undisturbed. Runoff volume, turbidity, and total suspended solids was measured in the runoff after each rain event. The sandy soil at the Coastal Plain site absorbed much of the road runoff prior to reaching the plots, while runoff volume at the Piedmont site frequently overtopped our 380 L collection tub. The effects of the tillage treatment will be discussed as well as the vegetation impacts." |
