Question

..................... is the measure of how fast water flows through the soil.​

Answer 1

Two major forces move liquid water through the soil pores: gravity and adhesion. ... It causes a downward force on water. When a soil is near saturation, the large pores are filled and water moves rapidly through them. When a soil is not saturated, the larger pores are empty and contribute little to flow.

Answer 2

Explanation:

The force of gravity is one factor. Just as water at a higher elevation on a street tends to run down to a lower elevation due to gravity, so water in a soil tends to move downward due gravity. A second factor is the attraction of the soil surfaces for water.
