Quantitative characterization of solute transport processes in an undisturbed unsaturated soil by means of electrical resistivity tomography (ERT) Inaugural-Dissertation zur Erlangung des Grades Doktor der Agrarwissenschaft (Dr. agr.) der Hohen Landwirtschaftlichen Fakultät der Rheinischen Friedrich-Wilhelms-Universität zu Bonn vorgelegt am 7. Mai 2009 von Johannes Köstel aus Offenburg, Deutschland Referent: Prof. Dr. H. Vereecken Korreferenten: Prof. Dr. A. Kemna Tag der mündlichen Prüfung: 23. Oktober 2009 Erscheinungsjahr 2010Gedruckt bei: 2 Acknowledgements I firstly thank my promoter Prof. Harry Vereecken, head of ICG-4, Agrosphere, Forschungszentrum Jülich, and Prof. Andreas Kemna, formerly head of research group ‚Hydrogeophysical Imaging and Characterization’ at ICG-4, presently Rheinische Friedrich-Wilhelms-Universität Bonn, for the opportunity and support to conduct this research. This Ph.D. project would have led to nowhere without the support of many colleagues and the good working atmosphere at Agrosphere institute. I am very grateful to Prof. Andreas Kemna, Prof. Mathieu Javaux, Prof. Jan Vanderborght, and Prof. Harry Vereecken for numerous discussions on the Ph.D. project and for their comments on early drafts and parts of this manuscript.
