Deep Learning Inversion of Electrical Resistivity Data [PDF]
The inverse problem of electrical resistivity surveys (ERSs) is difficult because of its nonlinear and ill-posed nature. For this task, traditional linear inversion methods still face challenges such as suboptimal approximation and initial model ...

Preliminary study on the contribution of osmotic effects for the electrical resistivity of sands [PDF]
Electrical resistivity of soils can be used to evaluate the level of contamination in soils in geophysical prospection tests. The chemical composition of pore fluid also corresponds to a given water potential, named as osmotic suction.
