► Tension infiltrometry gives reliable hydraulic parameters for soil water simulations. ► Time-variable hydraulic properties improve near-surface soil water simulations. ► Reduced and no-tillage improve water storage under dry climatic conditions. Simulating near-surface soil water dynamics is chall...
