“…As a matter of fact, such type of relation was successfully used for water content estimation in a number of studies (Binley et al, 2002;Hagrey et al, 2004;Loperte et al, 2006;Zhou et al, 2001). In this research, the experimental data fitted to the exponential model, even though R values were lower than the ones found by other authors (Fukue et al, 1999;Hagrey, 2007;McCarter, 1984;Michot et al, 2000;Montoroi et al, 1999). Such finding could be ascribed to several causes.…”

“…Finally, the relation found in this experiment was built using ρ data obtained in situ and θ v measurements carried out according to the gravimetric method. In the available literature, relations with high R values were obtained by data coming from experiment performed partially or totally under controlled laboratory conditions (Hagrey, 2007;Michot et al, 2000). As a matter of fact, under semi-arid conditions, significant vertical gradients of soil moisture can occur very often.…”

“…At the end of experimental period, the drying pattern was influenced down to the third soil horizon by the maize rows. Michot et al (2003), Hupet and Vanclooster (2005) and Srayeddin and Doussan (2009) observed similar patterns in the maize field due to root water uptake (Michot et al, 2001). Although drying fronts went down with time, the general drying pattern (due to alternation of row/inter-row) remained, with dry zones under the maize rows and at the soil surface, even after consequent rainfall events (for instance 24 August, 9 September and 18 September 2009).…”

“…This technique was successfully used in solute transport experiments in a bare soil lysimeter (Binley et al, 1996;Koestel et al, 2008Koestel et al, , 2009aGarré et al, 2010), in large experimental tanks (Slater et al, 2002), in the field (Kemna et al, 2002;Cassiani et al, 2006), and in a forest (Oberdörster et al, 2010). Given the many factors influencing the soil electrical resistivity (Samouelian et al, 2005), soil conductivity was first used as a proxy for water content (Michot et al, 2001(Michot et al, , 2003Srayeddin and Doussan, 2009). However, more recently, a few studies tried to obtain the actual SWC distribution validated with TDR probes.…”

Abstract.A good understanding of the soil water content (SWC) distribution at the field scale is essential to improve the management of water, soil and crops. Recent studies proved that Electrical Resistivity Tomography (ERT) opens interesting perspectives in the determination of the SWC distribution in 3 dimensions (3-D). This study was conducted (i) to check and validate how ERT is able to monitor SWC distribution in a maize field during the late growing season; and (ii) to investigate how maize plants and rainfall affect the dynamics of SWC distribution. Time Domain Reflectometry (TDR) measurements were used to validate ERT-inverted SWC values. Evolution of water mass balance was also calculated to check whether ERT was capable of giving a reliable estimate of soil water stock evolution. It is observed that ERT was able to give the same average SWC as TDR (R 2 = 0.98). In addition, ERT gives better estimates of the water stock than TDR thanks to its higher spatial resolution. The high resolution of ERT measurements also allows for the discrimination of SWC heterogeneities. The SWC distribution showed that alternation of maize rows and inter-rows was the main influencing factor of the SWC distribution. The drying patterns were linked to the root profiles, with drier zones under the maize rows. During short periods, with negligible rainfall, the SWC decrease took place mainly in the two upper soil horizons and in the inter-row area. In contrast, rainfall increased the SWC mostly under the maize rows and in the upper soil layer. Nevertheless, the total amount of rainfall during the growing season was not sufficient to modify the SWC patterns induced by the maize rows. During the experimental time, there was hardly any SWC redistribution from maize rows to inter-rows. Yet, lateral redistribution from inter-rows to maize rows induced by potential gradient generates SWC decrease in the inter-row area and in the deeper soil horizons.

Electrical resistivity of the soil can be considered as a proxy for the spatial and temporal variability of many other soil physical properties (i.e. structure, water content, or fluid composition). Because the method is non-destructive and very sensitive, it offers a very attractive tool for describing the subsurface properties without digging. It has been already applied in various contexts like : groundwater exploration, landfill and solute transfer delineation, agronomical management by identifying areas of excessive compaction or soil horizon thickness and bedrock depth, and at least assessing the soil hydrological properties. The surveys, depending on the areas heterogeneities can be performed in one-, two-or three-dimensions and also at different scales resolution from the centimetric scale to the regional scale. In this review, based on many electrical resistivity surveys, we expose the theory and the basic principles of the method, we overview the variation of electrical resistivity as a function of soil properties, we listed the main electrical device to performed one-, two-or three-dimensional surveys, and explain the basic principles of the data interpretation. At least, we discuss the main advantages and limits of the method.
