DC Resistivity Monitoring of a Vineyard Château Couhins – Bordeaux – France

We performed a DC resistivity monitoring experiment during five months in 2003. Low, medium and high resolution measurements have been carried out at various locations of a vineyard. Parallel 2 dimensions dipole-dipole images help to specify the 3D geological sketch of the studied area down to three meters. General apparent resistivity mapping evidences the spatial variations of the summer drying of the subsurface. High resolution cross borehole tomography shows moisture variation at the vine stock scale, and short time interval such as the diffusion of a rainfall.
