• We propose an integrated electromagnetic‐hydrodynamic inverse modeling approach for identifying field‐scale unsaturated soil hydraulic properties and electric profiles from off‐ground time‐lapse ground‐penetrating radar data. Hydrodynamic modeling based on the one‐dimensional Richards' equation with homogeneous soil hydraulic parameters is used to physically constrain the full‐wave radar electromagnetic inverse problem in a closed loop. Significant effects can be observed of water dynamics on the time‐lapse radar data and numerical studies demonstrate the uniqueness of the inverse solution. The results suggest that the method is promising for non‐invasive characterization of the shallow subsurface and monitoring of its dynamics.
