YARAMANCI Technical University Berlin Dept. of Applied Geophysics Ackerstr. 71-76 13355 Berlin Germany E-mail: mohnke@geophysik.tu-berlin.de Introduction Magnetic Resonance Sounding (MRS) or Surface nuclear magnetic resonance (SNMR) is a non-invasive groundwater-exploration method that allows a direct determination of the water content and the estimation of permeability from the relaxation signal of excited hydrogen nuclei [1 2]. Whereas the signal amplitudes of MRS are proportional to the amount of water in the subsurface
