[en] Crosshole GPR full-waveform inversion (FWI) has shown a high potential to characterize the near surface at a decimeter scale which is crucial for flow and transport. GPR FWI provide high-resolution tomograms of dielectric permittivity and electrical conductivity, which can be linked lithological properties. This study tests the potential of time-lapse GPR FWI to monitor tracers of different geophysical properties (salt, heat, ethanol). Synthetic and preliminary field results show that both properties can resolve major transport processes.
