ResumoThe electrical resistivity and seismic velocity distributions over a buried hillside have been obtained using non‐invasive controlled experiments on coincident profiles and 2D image reconstructions. The optimal images are in structural agreement and allow the deduction of two opposite resistivity‐velocity trends in the near‐surface materials. For both trends, the resistivity (ρ) and p‐wave velocity ( V p ) are related in the form Log 10 ρ = mLog 10 V p + c with the respective constants m and c having different signs in unconsolidated and consolidated materials.
