    Content: Wo und wie schnell nehmen Wurzeln Wasser auf? Obwohl diese Frage in Pflanzen- und  Bodenwissenschaften von großer Bedeutung ist, gibt es nur wenige experimentelle Daten darüber, an welcher Stelle der Wurzeln eine transpirierende Pflanze das Wasser aus dem Boden erhält. Die Antwort auf diese Frage erfordert direkte und in-situ Messungen des lokalen Wasserflusses in die Wurzel hinein. Ziel dieser Arbeit war es, eine neue Methode zu entwickeln und anzuwenden, um den lokalen Wasserfluss in unterschiedliche Segmente der Pflanzenwurzeln zu quantifizieren.

    Content: Where and how fast do roots take up water? Despite its importance in plant and soil sciences, there is limited experimental information on the location of water uptake along the roots of transpiring plants growing in soil. The answer to this question requires direct and in-situ measurement of the local flow of water into the roots. The aim of this study was to develop and apply a new method to quantify the local fluxes of water into different segments of the roots of intact plants. To this end, neutron radiography was used to trace the transport of deuterated water (D2O) into the roots of l...

    Content: Konnektivitätsmaße; stochastische Rekonstruktion; stationärer Fluss; Stofftransport; hydraulisches Ungleichgewicht; Upscaling
    Content: connectivity metrics; stochastic reconstruction; stationary flow; solute transport; hydraulic nonequilibrium; upscaling
    Content: Fluss und Transport in natürlichen porösen Medien werden durch die Strukturheterogenität des Untergrunds bestimmt. Konnektivität ist ein wichtiger Aspekt jener Strukturheterogenität, der richtig erfasst werden muss, um Modelvorhersagen zu verschiedenen physikalischen Prozessen zu ermöglichen oder zu verbessern. Die vorliegende Arbeit präsentiert neue Erkenntnisse über die quantitative Beschreibbarkeit von Strukturkonnektivität und die komplexe Beziehung zwischen struktureller und funktionaler Konnektivität in Bezug auf die Hydrologie der ungesättigten Zone. Funktionale Konnektivität beschreibt dabei das effektive hydraulische Verhalten in Bezug auf stationären Fluss, Stofftransport und hydraulisches Ungleichgewicht. Numerische Simulationen zeigen, dass eine gute Reproduktion von Strukturkonnektivität auch zu einer guten Reproduktionen funktionaler Konnektivität führt. Strukturkonnektivität beeinflusst jedoch effektiven Fluss, Transport und hydraulisches Ungleichgewicht auf unterschiedliche Weise. Funktionale Konnektivität muss daher als ein prozess- und zustandsabhängiges Konzept aufgefasst werden.
    Content: Flow and transport in the subsurface are determined by the structural heterogeneity of natural porous media. Connectivity is known to be an important facet of structural heterogeneity that has to be captured adequately in order to facilitate or improve model predictions on diverse physical processes in porous formations. This thesis presents some novel insights into the approaches to quantify structural connectivity and the complex relationship between structural and functional connectivity in the realm of vadose zone hydrology. Functional connectivity is expressed as effective hydraulic behavior with respect to stationary flow, solute transport and hydraulic non-equilibrium during infiltration. Numerical simulations demonstrate that a good reproduction of structural connectivity also entails a good reproduction of functional connectivity metrics. However, structural connectivity affect upscaled flow, transport and hydraulic non-equilibrium behavior differently. Thus, functional connectivity has to be considered as a process and state-dependent concept.
