Silt fence的意思

Silt fence is a type of erosion control barrier that is commonly used in construction sites, along roadsides, and in other areas where soil erosion is a concern. It is designed to trap and prevent the movement of silt and other fine soil particles into nearby waterways, storm drains, or other bodies of water.

Silt fences are typically made of long, porous fabric that is anchored at one end and allowed to drape over the contour of the land. The fabric is porous enough to allow water to pass through, but it catches the silt and sediment that would otherwise be washed away by rain or construction activities.

Silt fences are an important tool in environmental protection, as they help to prevent the pollution of waterways and to maintain the quality of the surrounding ecosystem. They are often required by local regulations and building codes, and their use is particularly important in areas with high water tables, steep slopes, or sensitive environmental features.
