Three-dimensional structure of a highly heterogeneous soil horizon derived by Electrical Resistivity Tomography

Abstract

IntroductionThe soil consists in a natural filter of water transfer to the groundwater. Its structure influences water storage and transfer properties or gas diffusivity, which induce major consequences on both environment and agronomy. Knowing the soil structure is thus essential to predict the soil hydraulic functioning and the 3D characterization of the structure at the horizon scale is necessary to describe the hydraulic functioning of the soil. In heterogeneous horizons, the structure (n sc (...)
