Abstract

Observations of sediment yield from road segments in the Oregon Coast Range show that either heavy traffic during rainfall or blading the road ditch will increase erosion from forest roads. For the fine soils and high quality aggregate surfacing on the study plots, ditch blading increased sediment yield more than traffic equivalent to 12 log trucks per day. The combination of ditch blading and heavy traffic did not produce significantly more sediment than simply blading the ditch, a finding with important implications for sediment modeling and erosion control design. Increases in sediment production caused by traffic persisted after traffic ceased.
