Approximation of van Genuchten Parameter Ranges from Hydraulic Conductivity Data
Groundwater, 2023 Abstract The use of retention function and relative conductivity function is essential for the calculation of flow in a variably saturated media using the Richards equation. A widely used mathematical model for this is the Mualem‐van Genuchten model which requires the shape parameters and .
