The transition point between capillary water and adsorbed water is defined as the critical point (including the critical matric potential and the critical water content) of the soil water retention curve. It demarcates the energy and water content region where flow is dominated by capillarity or liquid film flow. Accurate estimation of the critical point is crucial for modeling water movement in the vadose zone.
