Lay Summary (English)

Lay summary
For nearly a century, applied earth scientists and civil engineers have been seeking a non-intrusive means to locate and quantify occurrences of water in the upper few hundred meters of the subsurface. Although a broad range of geophysical techniques provide much useful information related to groundwater occurrence and flow, until recently there has been no reliable method for directly mapping the location and amount of water. A rapidly developing method that has the potential to provide this information (and possibly also flow-related parameters) in a wide variety of environments is the surface nuclear magnetic resonance technique.

With the SNF equipment grant, supplemented by matching funds provided by ETH and the University of Lausanne, we have purchased a state-of-the-art NUMIS surface nuclear magnetic resonance system. The new equipment will be applied to (i) the Kappelen Test Site in western Switzerland, (a joint project between ETH, University of Lausanne and possibly University of Neuchâtel); (ii) the Baltenswil Test Site; (iii) diverse hydrogeophysical and related problems that involve water as the key environmental agent, such as geothermal reservoir characterisation and contaminant detection (a joint project between University of Lausanne and ETH); (iv) attempts to relate geophysical measurements to certain low-temperature geochemical processes (a joint project between University of Lausanne and ETH); (v) on-land regions of the Okavango Delta (a joint project involving ETH groups and the Government of Botswana); (vi) mapping water in structures characterised by very low electrical conductivity contrasts, in particular Karst systems in southern France and rock glaciers in eastern Switzerland (a joint project between ETH and BGRM, Orleans, France).
