Magnetic resonance and neutron imaging of infiltration into heterogeneous soil
Original language description
The subject of the contribution is to show the possibilities of combining the three-dimensional magnetic resonance imaging (MRI) and neutron imaging (NI) to investigate the complex water flow dynamics in natural soil. The infiltration outflow experimentwas conducted on undisturbed soil samples with concurrent imaging by i) MRI and ii) NI. Despite the experiment was conducted on two different samples, the experimental concept, type of soil and observed behaviour was the same. Additionally, both NI and MRI were used to image selected soil samples at various static water saturations. MRI of porous system and of soils in particular, is specific due to many issues related to the complex internal structure, varying pore sizes, interface interaction, etc. Insmall pores, due to very fast relaxation of hydrogen spins on solid-liquid interfaces, the MRI signal is difficult or impossible to detect with use of current MR scanners. On the other hand, the relaxation properties can be used to incre
