Subsurface characterization in constrained environments using towed Capacitively Coupled resistivity (CCR) imaging – Case studies

Year: 2026

Type: article

Abstract: Capacitive-coupled resistivity tomography (CCR) is a rapid, non-invasive, and reliable method for subsurface imaging. It is particularly effective in urban or heavily anthropized environments, where conventional resistivity measurement techniques are often limited. This article presents three investigation examples conducted by the GEOSCOP geophysics department in varied contexts: an urban area, a highway tunnel, and a hydraulic structure. CCR imaging distinguishes resistivity contrasts associated with variations in facies, backfill materials, and localized heterogeneities indicative of structural pathologies. Across these examples, it proves to be a robust tool for optimizing preliminary design investigations and monitoring high-risk areas.
