Erosion control refers to measures taken to prevent or reduce soil erosion, which is the process by which rocks and other particles are detached from their original location due to natural forces such as wind, water, or human activities. Erosion control methods include planting vegetation, using mulch or ground cover, terracing, building retaining walls, and implementing proper land management practices. The goal of erosion control is to protect the soil, prevent loss of fertile topsoil, reduce sediment runoff into water bodies, and maintain the natural landscape.
