The Boundary Element Method in the Sounding of Media with Ground Surface Relief
This chapter focuses on the new results obtained by the authors during application of the boundary element method (BEM) to the modeling of electrical resistivity tomography (ERT) data above a medium with ground surface relief. We show the influence of relief on the interpretation of results for 2D and 3D conductivity distributions. Each solution of the direct problem is compared using appropriate interpretation results based on different inversion programs. We present numerical data obtained for different model parameters and discuss the possible inaccuracies and errors that can arise during the interpretation processes associated with the relief.
