N2  - Ground-Penetrating Radar (GPR) is a non-invasive electromagnetic geophysical method, which is sensitive to variations of subsurface dielectric properties. With this, GPR has become a versatile tool in various fields of geophysics and the soil science. In particular the determination of field-scale soil water content has drawn considerable research interest over the past decade. However, the quantifiability of achieved results remains often contested. In this thesis, three approaches for a quantitative use of GPR in soil hydrology are presented. First, a new calibration approach is developed for quantifying near-surface soil water contents with GPR and its applicability is demonstrated in field applications.
Second, the ability of GPR methods for monitoring soil water dynamics is tested in well-controlled field experiments featuring imbibition into and drainage from a known subsurface structure. Finally, GPR applications are demonstrated in the broader context of developing monitoring schemes at a set of representative sites in a highly structured watershed.
