Answer:
I. Concrete sidewalks
Explanation:
One of the factor that affects the infiltration of water into the surface of the soil is the use of concrete sidewalks.
- A concrete sidewalk prevents water from infiltrating down into the soil profile.
- Infiltration deals with the movement of water into the soil or ground.
- It is the major source of ground water recharge.
- Also, infiltration makes water available for plants.
Concrete is impermeable and non - porous media
When concrete pavements are used, water will not be able to move into the ground. They run on the surface and collects into nearby streams and water bodies.
