Research for the Environment

Sascha Oswald

Research areas

  • Numerical modeling of reactive transport in soil and groundwater
  • Remediation strategies for regionally contaminated aquifers (including Natural Attenuation, Enhanced Natural Attenuation, Gas Sparging, Constructed Wetlands)
  • Application of non-invasive imaging methods to study dynamic processes in porous media
  • Urban hydrogeology (including soil-plant-groundwater interactions)
  • Variable density flow in porous media
  • Integrated water- and soil management

Key working areas

  • 2-D and 3-D imaging of flow & transport, biodegradation and plant uptake mechanisms via Magnetic Resonance Imaging (NMR), Neutron Radiography (NR) and Fluorescence Imaging
  • Simulations of biogeochemical reactions in the subsurface including degradation of organic chemicals and the transfer of heavy metals
  • Kinetic mass exchange at interfaces and gradients, e.g. at the surface of trapped gas bubbles, reactions fronts and permeability contrasts
  • Improvement of remediation and land use strategies

Current own research projects

  • Dynamics of heavy metal distribution in the rhizosphere – Non-invasive imaging by NMRI in a rhizobox system aided by numerical modelling, ETH Zürich, vom Schweizer Nationalfond.
  • Transport behaviour at reaction gradients ("NMR als Mittel zur Charakterisierung des biologischen Schadstoffaubbaus im Porenraum"), UFZ Project jointly with Dr. Frank Stallmach at University of Leipzig.
