Abstract
This paper begins with a review about geoelectrical monitoring based on subsurface visualization for investigation of geological and geotechnical environments using electrical potential and resistivity data by surface and subsurface electrode array systems, especially deals with consideration of simple predictable models in order to investigate very complex field cases of target or nontarget inhomogeneities.
At first, a watertank experiment with single Cu or plastic plate model has been studied as an aid to new resistivity information processing such as data composition approach, structure shift approach and data density methods by surface four electrode arrangement. Next, single prism sturucture simulation data based on surface and boreholes electrode arrays have been studied by the finite element 2D-3D algorithm in the cases of target and nontarget inhomogeneities. Furthermore, an advanced problem solving methods including electric field monitoring for waste low resistivity leakage has been proposed for the earth resources information engineering and the system predictive design.
