What is a purpose of sediment barriers during construction?

The purpose of sediment barriers during construction is to trap sediment from runoff. Sediment barriers, such as silt fences or straw bales, are installed around construction sites to prevent sediment-laden water from leaving the site. They act as a physical barrier that slows down the flow of water, allowing sediment to settle out before the water can escape. This helps to minimize the amount of sediment that enters nearby water bodies, which can lead to pollution and degradation of aquatic ecosystems. The effective use of sediment barriers is a key practice in erosion and sediment control, helping to maintain water quality and adhere to regulatory requirements during construction activities.
