Dynamical and Mechanistic Effects of High Pressure Fluids in the Earth's Crust
(2012-03-16)
Overpressurized fluids in the lithosphere play a significant role in a diverse range of globally observed natural hazards. Their occurrence during volcanic eruptions or earth degassing processes is apparent, but their ...
Numerische Untersuchungen zur Anatomie und Metamorphose seismoelektromagnetischer Effekte in porösen Medien
(2012-09-27)
Unter Seismoelektromagnetik versteht man die Erzeugung elektrischer und magnetischer Felder in einem vollgesättigten, porösen Medium als Antwort auf seismische Anregungen an der elektrischen Doppelschicht. Je nach Art der ...
Monitoring structural and physiological properties of crop roots using spectral electrical impedance tomography
(2017-06-09)
Non- or minimally invasive methods are urgently needed to characterize and monitor crop root systems, both on the laboratory and the field scale. Traditional research methods still overwhelmingly rely on manual labor, which ...
2-D Anisotropic Inversion of Frequency-Domain Induced Polarization Data
(2018-03-23)
Measured data in IP (time or frequency domain) are usually interpreted with inversion algorithms, which may be based on stochastic or iterative schemes for finding an optimal data-associated model of the subsurface. Despite ...
Pore-Scale Modelling of Induced-Polarization Mechanisms in Geologic Materials
(2019-03-20)
This thesis is concerned with mechanistic pore-scale models, which relate the induced-polarization (IP) response of geologic materials to the underlying physical and chemical processes. Although a sound understanding of ...
