La description

Silt fences, or temporary sediment control fences, often are the most visible form of erosion or sediment control on a construction site. Used properly, silt fences can limit the transport of eroded soil from disturbed areas. A silt fence is not an erosion control device; it is a sediment control device. As soil particles become dislodged due to human activity, rain, wind and/or other natural forces, they become sediment or “silt.” Silt fences are designed to control this sediment.
