LIDLayerSoil Properties

Evaporation rate [m/s].

Evaporation only takes place if the upper layer is unsaturated

Volume of pore water relative to total volume after the soil has been allowed to drain fully (as a fraction). Below this level, infiltration/vertical drainage of water through the soil layer does not occur.

This is a fraction, which must always be less than the Porosity, and larger than the WiltingPoint.

Flag specifying which method to use for soil infiltration and percolation (leakage).

Conductivity of soil [m/s], used by the Green Ampt infiltration method

Coefficient for conductivity of soil, used by the Green Ampt infiltration method.

Also called conductivity slope

Green Ampt infiltration computational variables and state

Suction head of soil [m], used by the Green Ampt infiltration method

Capacity to infiltrate from surface to soil, in [m/s]

Capacity to percolate (leak/infiltrate) from soil to storage, in [m/s]

Moisture fraction, volume of pore water relative to total volume (as a fraction).

This fraction is always between WiltingPoint and the Porosity.

Moisture fraction of last time step

Percolation rate. [m/s]

Speed of the water through the soil, effectively used as infiltration rate from soil to lower layer

Soil porosity; void volume fraction of total volume.

Thickness of soil layer [m]

Volume of free water per area [m] contained in soil. Bound water (below WiltingPoint) is not included

Volume of bound water relative to total volume, i.e. water content in a fully dried soil (as a fraction). The moisture content of the soil cannot fall below this limit.

This is a fraction, which must always be less than the Porosity, and the FieldCapacity.
