Focus: Determination of drivers of water, nutrient, and contaminant fluxes in catchments
The research encompasses the delineation of nutrient and contaminant sources as well as the recognition and quantification of biogeochemical matter transformations in surface and subsurface catchments across scales by means of stable isotope methods. Natural and anthropogenic radionuclides in concert with stable isotopes of the water molecule are utilized to provide information on water flow paths, on water travel and residence times, and on water exchange between different hydrological compartments for the implementation in conceptual hydrological, hydrogeological and reactive transport models.Team:

Research objectives:
- Delineation of nutrient and contaminant sources in surface and subsurface catchments
- Recognition and quantification of biogeochemical nutrient transformation and contaminant degradation processes
- Defining hydrological constraints of matter transformations in surface water catchments across scales and compartments (discharge-concentration-isotope signature-relationship)
- determination of reservoir size of groundwater bodies as well as assessment of vulnerability and degree of interrelationship between groundwater and surface water
- temporal and spatial structure of hydrological systems parametrized by natural stable and radioactive isotopes (and other tracer) methods ("dating")
- Determination of activity concentrations of natural and anthropogenic radionuclides in the environment and their use as an environmental tracer for the investigation of environmentally relevant processes and states
- Localization, investigation and assessment of increased natural activity concentrations in (fossil) groundwater (water resource management)
- Regions: Germany (Bode catchment), Austria (Erlauf catchment), Belgium (Geer catchment), Ireland, South Africa, Kazakhstan, Uzbekistan, Tajikistan
