Geophysical exploration for highlighting local hydrogeological conditions to extend the captation of tap water in Baden District, Switzerland. In the project, a series of geoelectrical profiles has been conducted in the version of electrical tomography (multielectrod) and Mise-a-la-Masse method.
By combining these methods, it was possible to highlight the preferential route of the groundwater flow both horizontally and in depth. The results allowed the conducting of excavation works in order to install the collection piping.
