Gabions are commonly used in which applications?

• A. A protective coating for pipelines.
• B. A type of container for injection wells.
• C. A device for measuring ground motion.
• D. A cage or box filled with rocks for civil engineering and landscaping.

Answer: (D)

Gabions are rock-filled cages used in civil engineering and landscaping to control erosion and stabilize slopes. They’re wire mesh boxes that are filled with stones and stacked to form permeable, flexible barriers. This permeability allows water to drain through, reducing hydrostatic pressure behind the structure, while the rock fill provides weight and stability. Their flexibility helps them tolerate ground settling and movement without cracking, making them ideal for riverbanks, channel stabilization, and hillside support. The option describing a cage or box filled with rocks for civil engineering and landscaping matches this use exactly, while the other descriptions refer to a protective coating for pipelines, a container for injection wells, or a device for measuring ground motion, none of which describe gabions.
