Infiltration is the downward movement of water into the soil. It occurs when precipitation or surface water penetrates the soil surface. Infiltration rate is a measure of the rate at which a particular soil is able to absorb rainfall or irrigation. Infiltration and Infiltration rate are often used interchangeably. WebWhat is infiltration rate? The infiltration rate velocity at which water disperses into the ground. It is usually measured in m/s. The lowest percolation rate at which a soakaway is still efficient is 1 x10-6 m/s. The infiltration rates depend on the type of soil encountered on site.
