Abstract
Recently geotechnical and environmental geophysics has become contributing toward solving problems in groundwater delineation, evaluation and protection, landfills, earth and water contamination, chemical waste disposal, nuclear waste disposal, earthquake risk evaluation, radon emanations, landslides, land subsidence, crop-land salinization, and general geoengineering. In this paper, geoelectrical information measurements including computerized subsurface visualization mainly by electrical sensitivity analysis methods are discussed.
