Using high-resolution electrical resistivity maps in a watershed vulnerability study

Michel Dabas, Thomas Jubeau, Dominique Rouiller, Jean-Marie Larcher, Severine Charriere and Thibault Constant illustrate with a French case study the contribution for agricultural purposes of high-resolution geophysics and specifically apparent electrical resistivity ER) measurements at three depths of investigation using a specially developed ARP system to determine the intrinsic vulnerability of a water catchment area to pollution hazard.
