“…While self-potential mapping has been applied for a long time to detect preferential fluid flow pathways in embankments and earth dams (Bogoslovsky and Ogilvy 1973;Gex 1980;Merkler et al 1989;Wilt and Corwin 1989;AlSaigh et al 1994;Howie 2001, 2003), it has recently emerged as a powerful quantitative method in determining flow properties in such environments (Rozycki et al 2006;Sheffer and Oldenburg 2007;Rozycki 2009;Bolève et al 2009). The self-potential method was used by Rozycki et al (2006) to diagnose quantitatively leakages in dams and embankments.…”

Low-frequency geoelectrical methods include mainly self-potential, resistivity, and induced polarization techniques, which have potential in many environmental and hydrogeological applications. They provide complementary information to each other and to in-situ measurements. The self-potential method is a passive measurement of the electrical response associated with the in-situ generation of electrical current due to the flow of pore water in porous media, a salinity gradient, and/or the concentration of redoxactive species. Under some conditions, this method can be used to visualize groundwater flow, to determine permeability, and to detect preferential flow paths. Electrical resistivity is dependent on the water content, the temperature, the salinity of the pore water, and the clay content and mineralogy. Time-lapse resistivity can be used to assess the permeability and dispersivity distributions and to monitor contaminant plumes. Induced polarization characterizes the ability of rocks to reversibly store electrical energy. It can be used to image permeability and to monitor chemistry of the pore water-minerals interface. These geophysical methods, reviewed in this paper, should always be used in concert with additional in-situ measurements (e.g. in-situ pumping tests, chemical measurements of the pore water), for instance through joint inversion schemes, which is an area of fertile on-going research.

“…Self-potential source generation and the modeling of the resulting SP field are well understood under saturated conditions (Sill, 1983;Sheffer and Oldenburg, 2007). A better understanding for multiphase conditions has developed in recent years through both theoretical and experimental work (e.g., Linde et al, 2007a;Revil et al, 2007;Jackson, 2010;Allègre et al, 2010), but there is still room for improvements.…”

Abstract. Self-potentials (SP) are sensitive to water fluxes and concentration gradients in both saturated and unsaturated geological media, but quantitative interpretations of SP field data may often be hindered by the superposition of different source contributions and time-varying electrode potentials. Self-potential mapping and close to two months of SP monitoring on a gravel bar were performed to investigate the origins of SP signals at a restored river section of the Thur River in northeastern Switzerland. The SP mapping and subsequent inversion of the data indicate that the SP sources are mainly located in the upper few meters in regions of soil cover rather than bare gravel. Wavelet analyses of the timeseries indicate a strong, but non-linear influence of water table and water content variations, as well as rainfall intensity on the recorded SP signals. Modeling of the SP response with respect to an increase in the water table elevation and precipitation indicate that the distribution of soil properties in the vadose zone has a very strong influence. We conclude that the observed SP responses on the gravel bar are more complicated than previously proposed semi-empiric relationships between SP signals and hydraulic head or the thickness of the vadose zone. We suggest that future SP monitoring in restored river corridors should either focus on quantifying vadose zone processes by installing vertical profiles of closely spaced SP electrodes or by installing the electrodes within the river to avoid signals arising from vadose zone processes and time-varying electrochemical conditions in the vicinity of the electrodes.Correspondence to: N.

“…He used the finite-difference method. Later, the streaming potential problem has been solved with the finite element approach (Wurmstich et al, 1991;Revil et al, 1999) and the finite volume approach (Sheffer and Oldenburg, 2007). The inverse problem consists in estimating the spatial distribution of electrical current sources from the measured self-potential signals.…”
