“…The first studies were performed in order to understand the impact of acid rain on the forested ecosystems (Dambrine, 1992;Dambrine et al, 1991Dambrine et al, , 1992Probst, 1992;Probst et al, 1990Probst et al, , 1992. From now, this data has allowed a large number of studies of the critical zone, focusing on the surface and top soil (0-10 m) domain and dealing with weathering, erosion, soil-atmosphere-vegetation interaction (Cividini et al, 2010;Gangloff et al, 2014;Goddéris et al, 2009;Pourcelot et al, 2008;Viville et al, 2012). Some other hydrological and hydro-geochemical studies allow describing the watershed hydrological functioning (Pierret et al, 2014;Viville et al, 2010), but suffer from the lack of spatially distributed and deep measurements.…”

Altered crystalline catchments are complex to study and model, as they present multi‐scale properties that control their hydrogeological behaviour and that are difficult to capture through a single geophysical imaging technique. Several volumes of interest must be sampled in order that both small‐scale (porosity, layering) and large‐scale (bedrock, weathering, faults) heterogeneities can be captured. We propose a geoelectrical model of the Strengbach catchment (Vosges Mountains, France), aiming at identifying the weathered structures and hydrogeological functioning of the aquifer. This is achieved through electrical resistivity tomography (ERT) and Controlled‐Source Audio‐Magnetotelluric (CSAMT) measurements and the use of appropriate measurement set‐ups. Meters‐scale shallow contrasts in the top soil, catchment‐scale shallow contrasts (top 30 m), and large‐scale vertical contrasts (up to 150 m) were resolved through this methodology. A structural interpretation is proposed, based on information provided by borehole measurements (gamma ray, optical images), analysis of sampled waters, and geological mapping. The limits at depth of the weathered and fractured granite, not detected by ERT, are detected by CSAMT. The analysis showed that the weathering state of the granite controls, at first order, the electrical resistivity signal. Shallow geoelectrical signal (first 30 m) is particularly driven by surface conductivity and hence by the clay content, whereas deep geoelectrical signal may arise from both the ionic content of pore waters and the clay content. A structural model is proposed and discussed. Geoelectrical contrasts revealed several qualities of weathered saprolite between the northern and the southern slopes. The inferred structural model and the distribution of weathered and unweathered crystalline units are considered for their respective effect on the hydrogeology, leading to the proposition of a new hydrogeological conceptual model of the catchment.
