Abstract
Magnetic Resonance Sounding (MRS) can provide valuable data to constrain and calibrate
groundwater flow and transport models. With this non-invasive geophysical technique, measurements of
water content and hydraulic conductivity can be obtained. We developed a hydrogeophyiscal forward
method, which calculates the MRS-signal generated by an aquifer pump test. A synthetic MRS-dataset
was subsequently used to determine the hydrogeological parameters in an inverse parameter estimation
approach. This was done for a virtual pump test with a partially and a fully penetrating well. With the
MRS data we were able to retrieve the hydrogeological parameters of the aquifer. However, the
differences in MRS signal in time were small compared to the electromagnetic noise. This limits the
applicability of the MRS technique for pump tests in which a partially penetrating pumping well is
used, as the limited drawdown around the extraction well causes smaller changes in received signal.
