Quantify the Pore Water Velocity Distribution by a Celerity Function

Figure 2

Constitutive relations of the effective saturation to logarithmic pressure head (a–c), dimensionless specific discharge (d–f), dimensionless average pore water velocity (g–i), dimensionless celerity (j–l), and kinematic ratio (m–o) in 5 typical soils under models of Brook-Corey, unmodified Mualem-van Genuchten, and modified Mualem-van Genuchten (illustrated in each column).
