(41C) Reduction of Soil Erosion on Forest Roads

[SlideRule]

An extract from Reduction of Soil Erosion on Forest Roads, USDA Forest Service, General Technical Report INT-264, JUL 1989, 24 pgs.

Results of onsite erosion control work from across the United States provide estimates of the amount of erosion reduction on forest roads from various treatments. Supplementary information includes the effects of slope gradient, soil characteristics, and ground cover. Estimates of sediment travel below fillslopes can be made, together with the combined effect of erosion control treatments of the running surface, road cut, and ditch.
Presents the expected reduction in surface erosion from selected treatments applied to forest road traveledways, cutslopes, fillslopes, and ditches. Estimated erosion reduction is expressed as functions of ground cover, slope gradient, and soil properties whenever possible. A procedure is provided to select rock riprap size for protection of the road ditch.

Excellent discussion with charts, equations, illustrations etc.

BEST!
