WebA soil moisture content of 150 mm/m. The soil moisture content can also be expressed in percent of volume. In the example above, 1 m 3 of soil (e.g. with a depth of 1 m, and a surface area of 1 m 2) contains 0.150 m 3 of water (e.g. with a depth of 150 mm = 0.150 m and a surface area of 1 m 2 ). This results in a soil moisture content in volume ... 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.
