Abstract

Magnetic Resonance Sounding enables the assessment of the water content, permeability and transmissivity of different layers of rock while remaining relatively cheap. MRS results obtained in five areas of Lower Silesia (south-western Poland) and verified by boreholes seem to substantiate a claim that this method can be used to successfully identify inflow zones. The results of researches showed, that water content and hydraulic conductivity depend on the type of deposits and the depth range from <0.5 to 38% and 0.001 to 30 m/d. In the case of aquifers minimum values were increased to 3.5%, and 0.17 m/d. The transmissivity obtained from pumping test was in the range 7-8691 m2/d. The MRS transmissivity ranged from 1-86 m2/d (fractured rock) to 14-15552 m2/d (porous rocks). The assessment of hydrogeological parameters of aquifer with the use of magnetic resonance showed that without calibrations process MRS method allows a low cost and non-invasive is able to estimate the hydraulic conductivity (or transmissivity), water content, thickness of the different layers, etc. of aquifers in localized favourable configurations (non-urban areas). In the case of high water content aquifers, the MRS analysis suggests that hydraulic conductivity and transmissivity are lowers about 20%, while in low or medium water content aquifers MRS hydraulic conductivity value is about 40-80% higher. The location meets the requirements of MRS measurements and knowledge of one parameters makes it possible to determine the next parameters with a much higher accuracy.
