👉 Cliff engineering is a specialized field focused on the design, construction, and maintenance of structures that protect against the erosive forces of cliffs and steep slopes. These structures, often referred to as cliff defenses, include retaining walls, buttresses, and gabions, which are wire-mesh containers filled with rocks or other materials. The primary goal is to stabilize the cliff face, prevent landslides, and safeguard infrastructure such as roads, buildings, and utilities. By reinforcing the cliff's natural stability, cliff engineering mitigates the risks posed by weathering, water infiltration, and seismic activity, ensuring long-term safety and sustainability of the surrounding environment.
