      abstract     = {Detailed knowledge of soil properties regulating soil water
                      availability for the vines is of prime importance for
                      optimal vineyard management. As soil characteristics may
                      vary strongly over short distances, specific tools are
                      required for efficient assessment and monitoring of soil
                      water distribution and dynamics with fine spatial
                      resolution. In that respect, ground-penetrating radar (GPR),
                      electromagnetic induction (EMI) and electrical resistivity
                      tomography (ERT) surveys were carried out in a vineyard in
                      southern France in order to produce high-resolution maps of
                      soil stratigraphy and to retrieve soil hydrogeophysical
                      properties of the different soil layers. The results
                      presented in this paper show large spatial variations in
                      vineyard soil properties, which are in accordance with the
                      distribution of the different soil types within the study
                      area. This is particularly observable from EMI and ERT data,
                      which show strong spatial correlation with large areas of
                      comparable values delimited by well-defined discontinuities,
                      revealing sharp variations of soil characteristics over
                      short distances. These discontinuities almost systematically
                      correspond to the limits of the vineyard plots, though areas
                      of contrasting soil electrical conductivity values are also
                      found within some plots. Furthermore, the patterns of soil
                      electrical conductivity and resistivity are in good
                      agreement with soil stratigraphy observed from GPR
                      measurements. Finally, these results also highlighted
                      anthropogenic soil compaction resulting from agricultural
                      practices during too wet soil conditions as a likely
                      explanation to vine vigor problems observed locally in the
                      vineyard, which is corroborated by the observation of lower
                      values of the normalized difference vegetation index (NDVI)
                      for the vine in zones where soil compaction was evidenced by
                      both geophysical measurements and soil profile description.
