Explanation

Riprap isn't a cool new genre of music; it's a layer of rocks or rubble placed on shorelines or slopes to stop erosion and protect the land. The term riprap refers to layers of large rocks, concrete, or other heavy materials used to stabilize riverbanks, coastlines, or steep hills. By absorbing the force of water or preventing landslides, riprap protects structures, natural habitats, and landscapes from erosion. Riprap is commonly seen along dams, road structures, and waterfronts, creating a barrier that serves as armor for the shoreline.
