ABSTRACT FIĽOVÁ, Gabriela: Evaluation of physical properties of forest soils by methods of electrical resisitivity tomography and ground penetrating radar. [Bachelor thesis] – Technical University in Zvolen, Faculty of Forestry, Department of Natural Enviroment. Bachelor thesis supervisor : Ing. Marián Homolák, PhD. Degree of professional qualification: Bachelor, shortthand „Bc.“. Zvolen TU, 2020. 36 p.The aim of the presented work was to research the applicability of non-destructive geophysical methods – electrical resistivity tomography (ERT) and ground penetrating radar (GPR), to use them on identical soil profile, to evaluate the measured data and compare their use for pedological survey.At the Bienska dolina locality, electrical rezistivity tomography captured a shallow subsurface layer with lower moisture and skeletality, a layer of gravel and deep clay impermeable layer for water. The ground penetrating radar didn´t capture this clay layer, even when using a lower frequency antenna. On the other hand, it captured in more detail the shallower horizons, where the individual layers were better distinguishable.The method of electrical resistivity tomography enables the analysis of the soil profile at greater depths together with the identification of the geological subsoil. Conversely, the ground penetrating radar method is more suitable for measuring shallow subsurface layers, which when using an antenna with a higher frequency captures more detailed structure and properties of individual soil layers, especially with more significant changes in soil properties.Keywords: electrical rezistivity tomography, ground penetrating radar, physical properties of soil, electrical properties of soil
