Which of the following is an example of a sediment containment system?

• A. SCS (Sediment Containment System) / Filter Bags
• B. Silt fences
• C. Vegetation establishment
• D. Diverted channels

Answer: (A)

Sediment containment systems are devices that physically hold sediment within a defined area while letting water pass, preventing sediment from leaving the site. An example is a sediment containment system such as filter bags or similar containment devices, which use fabric or bag structures to trap sediment-laden runoff and keep the sediment contained until it can be removed. This setup directly captures and confines sediment, addressing the problem at the source. Silt fences, while also aimed at controlling sediment, act more as barriers that slow runoff and encourage sediment to settle behind the barrier rather than actively containing it within a dedicated containment unit. Vegetation establishment reduces erosion by protecting soil surface but doesn’t provide a containment mechanism for accumulated sediment. Diverted channels change where water flows, not how sediment is contained once it’s in motion.
