Abstract
Magnetic resonance tomography using elongated transmitter and in-loop receiver arrays (MRTetra) is designed to efficiently image the two-dimensional aquifer structures. However, MRT suffers from limited abilities to resolve sharp boundaries. We make use of the GPR reflections to generate structural mesh boundaries for modelling of MRTetra and apply a definite sharp boundary constraint in the inversion of the surface NMR data. A comprehensive survey including GPR, MRT and other geophysical methods has been conducted at the test site Schillerslage, Germany. Inversion results of the surface NMR show that the imaging of water content and relaxation time T2∗is improved using the mesh including the GPR reflections, and further improved by applying the sharp boundary constraint. In addition, multiple datasets of MRTetra can be combined together to invert the water content and T2∗of the entire profile which provides a more stable and robust result comparing with separate datasets.
