Erosion control is the practice of preventing or
controlling wind or water erosion in agriculture, land development and
construction. This usually involves the creation of some sort of physical
barrier, such as vegetation or rock, to absorb some of the energy of the
wind or water that is causing the erosion. Effective erosion controls are
important techniques in preventing water pollution and soil loss. On
construction sites they are often implemented in conjunction with sediment
controls such as sediment basins and silt fences.
