Hydraulic parameters are required indicators to quantify characteristic properties in agricultural fields. This technical brief analyses numerically the effects of soil hydraulic parameters on the retrieved responses of thermal, moisture, and solute dynamics using a synthetic inverse modeling. The goal was to provide analysis insight into the role of hydraulic parameters as tool for interpretation of soil thermal and hydrochemical responses. The inverse results show good agreement and present excellent accuracy when compared to the retrieved responses and true values. Several simulations reveal relevant contributions of the saturated hydraulic conductivity and moisture content, the shape parameter as well as the pore-size indicator on the special distributions of thermal and hydraulic responses.
