HIGH RESOLUTION 2D INVERSION OF SEPARATED LOOP MAGNETIC RESONANCE SOUNDING (MRS) SURVEYS

The method of Magnetic Resonance Sounding (MRS) is conventionally used for 1D investigations of the water content distribution with depth. It has proved to provide essential information in hydrogeophysical surveys concerning the total amount of mobile water and thus improving the aquifer localization and characterization significantly. Latest work extend the application of MRS surveys to 2D investigations of the water content distribution (Hertrich, 2005; Hertrich et al., 2005). These are the development of MRS measurements with separated loops, providing a superior sensitivity to shallow depth and the full 2D inversion of a set of soundings along a profile to recover the lateral water content distribution with high resolution. The new layout and inversion technique is assessed on synthetic data and approved on a real field survey.
