In areas with good soil coverage and vegetation, runoff rates typically decrease. The presence of vegetation plays a crucial role in capturing rainwater, which allows it to infiltrate the soil rather than flowing over the surface as runoff. The roots of plants help to create space in the soil, improving its capacity to absorb water. Additionally, vegetation slows down the movement of water, allowing more time for it to percolate into the ground.

Good soil coverage prevents erosion as well, which can damage the soil structure and reduce its ability to retain water. Therefore, in well-vegetated areas, more water is absorbed into the ground, leading to lower runoff rates. This is particularly important in managing water resources and reducing the risk of flooding. Careful management of vegetation and soil health is essential for maintaining these benefits.
