PhD position (65%, doctoral candidate)
Model development for describing macropore-matrix mass transfer during preferential flow (Kennziffer 33-2017)
The project is funded by the Deutsche Forschungsgemeinschaft (DFG) for 3 years; salary is according to the German tariff E13 TV-L (65%); candidates should be aiming at a doctorate.
The successful candidate will play a central role in this DFG-funded project that deals with the exploration of mass transfer processes through the macropore-matrix interface, which is a key for a quantitative understanding of preferential flow in structured soil. This local-scale movement of water and dissolved chemicals is depending in a complex way on the small-scale distributed composition of the surfaces of biopores and shrinkage cracks and fissures. The project is aiming at the development of an â€œeffectiveâ€� macroscopic exchange term for reactive solutes in two-domain models that can be related to measurable properties of the interface. Experiments and numerical simulations will be carried out together with cooperation partners from ZALF and with scientists from the Czech Technical University (Prague) and the University Kassel (Witzenhausen). The results will contribute to improving the modelling of preferential transport of reactive solutes in soils.
