Sensitivity analysis of VG model parameters for infiltration in undisturbed loess under ponding conditions using the HYDRUS-1D model [PDF]

Scientific Reports
It is difficult for remolded loess to reproduce the infiltration law of water in natural loess, resulting in inaccurate parameters of the Van-Genuchten model (VG model) obtained by inversion, which subsequently affects the changes in the moisture field ...
