Which of the following are common examples of sediment barriers?

The most appropriate choice when identifying common examples of sediment barriers is the combination of bales, silt fences, and depressions. Each of these serves a specific purpose in controlling sediment movement and preventing erosion during construction or land-disturbing activities.

Bales—often made of straw—are used to slow down water flow and reduce sediment transport. They are effective at filtering out sediment-laden water, making them a practical choice for managing erosion on sites where runoff can carry sediment into nearby water bodies.

Silt fences consist of a geotextile fabric supported by wooden stakes. They are designed to intercept sediment from runoff and allow water to flow through while filtering out particles. Silt fences are widely used in construction sites to control sediment before it can reach stormwater systems or natural water bodies.

Depressions can function as sediment barriers by creating a low area that captures and slows down runoff, allowing sediment to settle out of the water before it can be carried downstream. Although this is a less conventional sediment barrier compared to silt fences and bales, it plays an important role in a comprehensive erosion and sediment control plan.

The other choices include combinations that may have one or two correct elements, but none encapsulate the set of effective sediment barriers as
