Which practice is used to manage sediment erosion during construction activities?

Silt fences are a widely recognized practice used to control sediment erosion during construction activities. These temporary barriers, typically made of geotextile fabric supported by stakes, are installed around the perimeter of a construction site. Their primary function is to intercept and detain sediment-laden runoff, allowing sediment to settle out of the water before it can be discharged into nearby water bodies.

By capturing sediment, silt fences help to reduce the impact of erosion on the surrounding environment, protecting water quality and minimizing the risk of sedimentation in streams and rivers. They are particularly effective in areas where soil disturbance is taking place, as they can adapt to changing site conditions and assist in managing runoff during rainfall events.

The use of silt fences is a critical component of stormwater management practices, especially during construction periods when the soil is exposed and more susceptible to erosion. This makes them a vital tool for maintaining compliance with environmental regulations and protecting local ecosystems during construction activities.
