Self‐potential signals associated with preferential ground water flow pathways in a buried paleo‐channel

The flow of ground water in a buried permeable paleo‐channel can be observed at the ground surface through its self‐potential signature. We apply this method to delineate the Saint‐Ferréol paleo‐channel of the Rhone River located in Camargue, in the South East of France. Negative potentials, ∼−30 mV... View More
