Interface urban hyporheic zones

  • Common aim: We aim at a mechanistic understanding of interface processes in urban hyporheic zones (HZ), at enlightening the relevance of the interface for the retention of organic micropollutants and at an identification of the close coupling of hydrological, microbiological and chemical processes.
  • Key processes: multidimensional flow and reactive transport, near bed turbulence, contaminant/micropollutant retention/degradation, biotic and abiotic aerobic and anaerobic transformations (including bank filtration), redox gradients, ecological consequences.
  • Common approaches: in situ investigations and manipulations of hydrology, microbiology, biogeochemistry and micropollutants on small scales, column and batch experiments, flume, multidimensional flow and reactive transport modelling based on measured data (e.g. Erpe experiments), creation of knowledge for improved design of river restoration.
  • Collaboration: H2 will model measurements of H1; H4 and H1 will conduct joint studies at the same sites to couple microbiology, biogeochemistry and hydrology; investigations of H1 and H3 at their different sites will be compared for a better process understanding; H2 and S2 all use OpenFOAM model; H4 and S1 will collaborate on biofilms; collaboration with the modelling postdoc; co-supervision of H1 by Prof. Okke Batelaan from Flinders University, Adelaide (expert in groundwater hydrology and modelling), including joint measurements at a study site in Australia, collaboration with H3 by Prof. Lorenz Adrian (expert in analytical and water chemistry, UFZ & TUB).
