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. The table below shows a description typical infiltration values. WebJun 13, 2024 · The infiltration rate for the vegetated soil was generally faster than for the fallow soil, regardless of plant type and age (Fig. 3, Tables 2 and 3: except for the 2 week old grass). Root growth and penetration therefore might have created sufficient macro-pore space in the soil matrix to enhance infiltration.
