What does installing silt fences primarily help to achieve?

Installing silt fences is primarily aimed at trapping sediment from disturbed areas, making it an essential tool in sedimentation and erosion control practices. When soil is disturbed, especially during construction or land clearing, it becomes more susceptible to erosion by wind and water. Silt fences act as a barrier that intercepts sediment-laden water as it flows across the site, effectively filtering out the soil particles and allowing cleaner water to pass through.

This process helps to prevent sediment from entering nearby water bodies, which can lead to pollution and degradation of aquatic ecosystems. By controlling sediment movement, silt fences help maintain the integrity of the landscape and protect water quality, while also promoting responsible land management practices.
