Hydrogeophysics faces the challenge of providing the necessary information for understanding the presently unknown impact and consequences of anthropogenic activities on the shallow subsurface and associated ecosystems. Improving the information delivery is investigated by the ground-penetrating radar method, combined with full waveform inversion. Moreover, we investigate the practical application of interferometry applied to  electromagnetic noise at ground-penetrating radar frequencies. A new approach to seismo-electric imaging aims to retrieve the coupling coefficient between elastic wave motion and electric field disturbances. This parameter can provide information on the bulk hydraulic permeability. Two applications are:
