What is an example of a physical method used in erosion control?

Adding mulch to the soil exemplifies a physical method used in erosion control because it creates a protective barrier on the soil surface. This barrier helps to reduce the impact of raindrops on the soil, thereby minimizing soil displacement and erosion. Additionally, mulch can improve soil moisture retention, support plant growth, and enhance soil structure, which collectively contribute to better erosion management. Physical methods like this directly interact with the earth’s surface to prevent erosion, making them effective for stabilizing soil in vulnerable areas.
