Most of the potential erosion problems are caused by one or more of these factors:
For safety, in steep terrain logging roads could be insloped and water channelled to culverts and removed. An alternative to culverts is broad-based dips. These are installed after the basic roadbed is constructed. They are good for erosion control on both skid roads and haul roads and can be used where road grades do not exceed 10%. Here is a spacing formula for broadbased dips:
Spacing=100 feet + (400/Road Grade %)
