Abstract
Time-lapse geophysical imaging of tracer tests is essential to infer channelized transport properties. Cross-hole ground-penetrating radar (GPR) tomography is a high resolution imaging method to characterize the near-surface. We present preliminary results of crosshole GPR full-waveform inversion of time-lapse synthetic data during a saline tracer test. The tracer movement was obtained from a 3D transport simulation in a hydrogeological model representing the Krauthausen aquifer where in future also field tests will be performed. The full-waveform inversion accurately resolved the infiltrated tracer distribution in the plane within decimeter scale. The results indicate the potential of GPR full-waveform inversion for saline tracer detection and high-resolution time-lapse transport characterization.
