“…A combination of the SNMR method with the time‐domain electromagnetic (TDEM) method has been applied not only to detect the presence of groundwater, but also to obtain quantitative information about water content and salinity at various sites in Israel ( Goldman et al . 1994 ; Gev et al . 1996 ).…”

“…Since both the phase and the amplitude of the surface NMR (SNMR) signal are affected by the electrical conductivity (Shushakov and Legchenko 1992;Trushkin, Shushakov and Legchenko 1995;Shushakov 1996), the conductivity distribution should be taken into account in the inversion of the data. A combination of the SNMR method with the time-domain electromagnetic (TDEM) method has been applied not only to detect the presence of groundwater, but also to obtain quantitative information about water content and salinity at various sites in Israel (Goldman et al 1994;Gev et al 1996).…”

The surface nuclear magnetic resonance (SNMR) method has been tested at a site in Haldensleben, northern Germany, to assess the suitability of this new method for groundwater exploration and environmental investigations. More information is obtained by SNMR, particularly with respect to aquifer parameters, than with other geophysical techniques. SNMR measurements were carried out at three borehole locations, together with 2D and 1D direct current geoelectrics, as well as ground‐penetrating radar, and well logging (induction log, gamma‐ray log and pulsed neutron‐gamma log). Permeabilities were calculated from the grain‐size distributions of core material determined in the laboratory. It is demonstrated that the SNMR method is able to detect groundwater and the results are in good agreement with other geophysical and hydrogeological data. Using the SNMR method, the water content of the unsaturated and saturated zones (i.e. porosity of an aquifer) can be reliably determined. This information and resistivity data permit in situ determination of other aquifer parameters. Comparison of the SNMR results with borehole data clearly shows that the water content determined by SNMR is the free or mobile water in the pores. The permeabilities estimated from the SNMR decay times are similar to those derived from sieve analysis of core material. Thus, the combination of SNMR with geoelectric methods promises to be a powerful tool for studying aquifer properties.

“…Both MRS equipment and its interpretation software have been well tested and proved their reliability in areas where the electrical conductivity of the subsurface is relatively low and does not cause significant phase shifts in the MRS signal (Schirov et al, 1991;Gev et al, 1996;Yaramanci et al, 1999, Wyns et al, 2004Baltassat et al, 2005;Vouillamoz et al, 2005). However, MRS can be applied not only for studying fresh-water aquifers, but also in areas where salt-water intrusion renders the subsurface electrically conductive.…”

“…With this technique the amount of groundwater in the subsurface can be directly determined. MRS was first tested in 1978 by Russian physicists (Semenov et al (1982) in Goldman et al (1994)) and it has since then been continuously developed and tested in many parts of the world (Schirov et al, 1991;Goldman et al, 1994;Lieblich et al, 1994;Gev et al, 1996;Legchenko et al, 1997;Yaramanci et al, 1999).…”
