Abstract: Soil is the natural material that covers most of the dry surface of the earth. It is the product of mechanical, chemical and biological interactions of different types of elements. Soils have a very complex composition and high variability in their occurrence and properties. The non-homogeneous mixture and interaction of their components and the changes induced upon usage ensures the complexity of their structure and a comfortable variable spatial distribution over the surface of the planet. The soils components can be found in nature in all the three aggregation states of matter: the solid state, the liquid state and the gas state. In spite of their complex structure and composition, soils can be easily handled and studied by a variety of methods. [Koorevaar, 1983] Prediction of water movement in soils is a controlling factor in various processes of interest in water resources management such as: the runoff generation, the water and nutrients supply to vegetation, the groundwater recharge and contamination. From the physics point of view water distribution and transport in unsaturated soil represents a rather complex problem of porous media hydraulics. Among various techniques developed for investigating hydraulic phenomena in soils, Nuclear Magnetic Resonance (NMR) can be used successfully for the characterization of natural porous media.
