TL;DR: There have been major improvements in instrumentation, field survey design and data inversion techniques for the geoelectrical method over the past 25 years as mentioned in this paper, which has made it possible to conduct large 2D, 3D and even 4D surveys efficiently to resolve complex geological structures that were not possible with traditional 1-D surveys.

TL;DR: In this paper, two strategies for obtaining the maximum spatial resolution in electrical resistivity were presented for tomography surveys using a limited number of four-electrode measurement configurations, and their execution times were analyzed in terms of the number of cells in the inverse model.

TL;DR: In this article, a geoelectrical investigation of a slow moving earth slide in Lower Jurassic Lias Group rocks of the Cleveland Basin, UK, is described, which includes a reconnaissance survey phase using two-dimensional electrical resistivity tomography (ERT), resistivity mapping, self-potential (SP) profiling and mapping, followed by a detailed investigation of an area of the landslide using three-dimensional (3D) ERT and selfpotential tomography.

TL;DR: In this paper, an Automated time-Lapse Electrical Resistivity Tomography (ALERT) system has been developed for the long-term monitoring of coastal aquifers, which can provide early warning of potential threats to vulnerable water systems such as overexploitation, rising sea levels, anthropogenic pollutants and seawater intrusion.

TL;DR: Whiteley et al. as discussed by the authors presented a review of the state of the art of geophysical monitoring applied to moisture-induced landslides, focusing on technical and practical uses of time-lapse methods in geophysics applied to monitoring moistureinduced landslide.
