Abstract: Quantifying matric potential is essential for predicting groundwater flow within the vadose zone. Current methods of determining matric potential consist of invasive instruments such as tensiometers, which can alter the natural hydrogeological state of the vadose zone. Nuclear Magnetic Resonance (NMR) is a non-invasive geophysical method that is sensitive to the presence as well as physical and chemical environments of hydrogen in a porous media. This study consists of a joint laboratory and field study to confirm the hypothesis: NMR relaxation times can be used to determine matric potential.
