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.
