Horton Fields

Fields

F0 Infiltration rate at start Unit: [m/s]
Fc Infiltration rate at end Unit: [m/s]
Ft Infiltration rate at current time step. Unit: [m/s] Computational variable.

This is stored and used when switching from dry to wet mode, in order to get a smooth transition of infiltration rates.

Kdry Time constant for dry period (inverse Horton's equation) Unit: [1/s]
Kwet Time constant for wet period (horton's exponent) Unit: [1/s]
Tdry Time of the dry Horton mode. Applicable only when HortonMode is Dry

When approaching infinity, the start infiltration rate has been recovered

Unit: [s] State variable.
Twet Time of the wet Horton mode. Applicable only when HortonMode is Wet

A value of zero matches the start infiltration rate.

Unit: [s] State variable.
