Description: Das Projekt "Research group (FOR) 831: Dynamic Capillary Fringes - A Multidisciplinary Approach" wird vom Umweltbundesamt gefördert und von Karlsruher Institut für Technologie (KIT), Institut für Ingenieurbiologie und Biotechnologie des Abwassers durchgeführt. Capillary fringes are highly dynamic zones at the interface between water-saturated aquifer and vadose zone, where steep biogeochemical gradients and thus high bioactivities are expected. Since the accessibility of this dynamic region in the field is very limited, well controlled bench and larger scale laboratory experiments to elucidate physical (flow, diffusion, dispersion), geochemical (dissolution/precipitation) and biological (metabolism, excretion, biofilm formation) processes in the capillary fringe and their interaction under transient conditions are planned. The focus will be on the reactive transport of organic and inorganic pollutants and on the influence of suspended groundwater bacteria, biofilms and metabolic products on mass transfer and turnover processes. Emphasis is directed on innovative high resolution (time and space) sensors and on spectroscopic tools for quantification of concentration gradients. In parallel to the experimental work the development and the implementation of a flexible simulator for coupled multiphase flow and reactive transport are pursued. The numerical model should be flexible enough to accommodate the experimental setups and relevant processes investigated experimentally in the different projects. State-of-the-art numerical methods and high-performance parallel computing will be used to obtain accurate solutions.
