| 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. |
