How does compaction affect erosion potential?

Compacted soil is less likely to erode because the process of compaction increases soil density and stability. When soil particles are pressed closer together, there is less pore space, which can reduce the movement of water through the soil. This tightness typically leads to better structural integrity of the soil, making it more resistant to the forces that drive erosion, such as wind and water runoff.

However, while compacted soils can resist erosion, the reduced pore space also disrupts water infiltration. This means that when it rains, water may accumulate on the surface instead of percolating down into the ground, increasing the potential for runoff. This runoff can carry sediments away, ultimately affecting erosion rates in adjacent or downstream areas.

Therefore, while compacted soil exhibits greater resistance to direct erosive forces, it can inadvertently lead to other forms of erosion due to surface water runoff that exceeds the infiltration capacity. This dual nature of compaction makes it an important consideration in erosion control practices.
