Unidimensional Vertical Electrical Soundings involving uneven soil surfaces: improving the apparent resistivity measurements for soil modelling

, Gabriel Asensio, Jorge Moreno, Eduardo Faleiro
The influence of a non-flat uneven soil surface on the soil apparent resistivity measurements in unidimensional Vertical Electrical Sounding is analysed. The sounding in a real uneven soil surface is simulated by using a soil model, which allows the semi-analytical expressions valid for perfectly plane soils to be used. In addition, real Wenner electrodes properly calibrated are used, and the differences with a sounding in an equivalent soil with a flat surface are highlighted. Due to the loss of symmetry around the centre of the Wenner array, measurements along different directions are needed and the mean value of the distributions of the measures is assigned to the value of the apparent resistivity. Furthermore, for the purpose of reducing the width of such distribution, the use of electrodes of increasing length is suggested within limits. Finally, the proposal of a multi-layered soil model with an uneven surface based on the Wenner measurements is discussed.
