A rock barrier, also known as a rock wall or stone boundary, is a structure built from rocks to prevent soil erosion and protect buildings and landscapes from natural disasters such as floods, landslides, and avalanches. Other synonyms for rock barrier include rock fence, stone fence, rock embankment, stone hedge, rock dam, stone dike, rock dyke, rock levee, stone revetment, rock breakwater, and stone protection. These structures have been used for centuries by farmers, engineers, and architects to create sturdy and durable walls and structures that withstand the test of time and harsh nature. Whether for decorative or functional purposes, rock barriers have become an important aspect of modern construction and design.
