Definitions Soil erosion is the wearing away of the earth s surface by water and wind. It includes splash, rill and gully erosion.
Broken slopes are variable, complex or benched slopes.
Water-restricting layer refers to any impermeable, dense layer that restricts the downward flow of water, but does not necessarily impede root growth. It can be compact or cemented layers, bedrock or the permanent water table. Erosion of forest soils remains low when surface organic layers are intact. After mineral soil is exposed, rates of erosion are initially high and then decline after the first year. Therefore, to be effective, erosion control measures must be applied promptly.
