Cartographie de l’épaisseur des sols sur substrat hétérogène : approche par méthodes électriques et électromagnétiques

Abstract : Owing to the automation of the measurements, geophysics is now commonly used to predict soil thickness over large areas in addition to punctual information given by soil augering. Among the various geophysical tools, the methods based on electrical resistivity measurements give good results providing that the bedrock is homogeneous. In this study we use electric and electromagnetic methods to map soil thickness over an area with heterogeneous bedrock. Geostatistical analysis allows eliminating the bedrock variability influence. The most efficient predictions are obtained when integrating topographic slope to the resistivity data.
