Moisture Equation
- Matric Head form of Richard’s eq.
- Assumes:
- Isothermal conditions (decoupled from temperature)
- Vapour flux is negligible
Temperature Equation
- Function of soil moisture
- Assumes:
- Effect from differential heat of wetting is negligible
- Effect from vapour flux is negligible
