MRS: A new geophysical technique for groundwater work

摘要

During the last 10 years, applied geophysics techniques have made significant progress in the exploration, quantification, and management of groundwater (GW) through wider applications of classic techniques and their integration. These include resistivity, including resistivity imaging and vertical electric sounding (VES); induced polarization (IP); spontaneous polarization (SP); time- and frequency-domain electromagnetics (TDEM, FDEM); ground-penetrating radar (GPR); very low-frequency EM (VLF); seismic; magnetic; gravity; and gamma-ray spectrometry. During that ten-year interval, however, one technique that stands out as truly new and highly relevant for. GW is magnetic resonance sounding (MRS), a field application of nuclear magnetic resonance (NMR).
