UZ Soils Editor

The UZ Soils Editor is used to define the saturation-pressure and the satura­tion-conductivity soil functions.

See UZ Soil Properties Editor (V1 p. 409).

Note: the units of pressure in the UZ Soils Editor are pF. This is defined as the base 10 logarithm of the suction expressed in cm of water. To convert between MPa and pF, first convert MPa to cm of water. The conversion factor is 10200 cm/MPa. Drop the negative sign because you cannot take the loga­rithm of a negative number. Finally, take the base 10 logarithm to get pF. For example, -1 MPa equals pF 4.01.
