WebWater from a water source passes through the top of the soil core, and the steady state flow rate is measured. That value is then used to determine the infiltration rate. Corrections are made for both constant head and falling head techniques to go from i (the infiltration rate) to a K s value (representative of a 0 pressure head influence). 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 ...
