What is one of the three purposes of soil roughening?

Soil roughening is a technique primarily aimed at improving soil stability and performance in controlling erosion and sedimentation. By creating a rough surface on the soil, this practice effectively reduces the speed of water runoff and increases the infiltration of water into the soil. This reduces the potential for soil erosion, which is a significant concern in areas prone to heavy rainfall or where construction activities have disturbed the soil.

The increased roughness disrupts the flow of water, allowing it to spread out and soak into the ground rather than run off quickly, which can lead to soil loss and sedimentation in nearby water bodies. Therefore, the contribution of soil roughening to reducing erosion is critical in maintaining soil health and protecting water quality, making this purpose essential in erosion control practices.
