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. |
