  1. Investigate the ecohydrological fluxes of the soil-plant-atmosphere continuum at high temporal and spatial resolutions
  2. Analyze the effects of different land use types on water partitioning using stable water isotopes
  3. Integrating field data into an ecohydrological model to quantify ecohydrological fluxes of the soil-vegetation-atmosphere interface


  1. Developing setup of real time in situ monitoring for soil & plant water isotope dynamics with field experiments at the Lake Müggelsee, Berlin Bayesian mixing model to identify root water uptake depths
  2. Destructive soil sampling with direct equilibrium method at various land use types at the rural Demnitzer Millcreek catchment, Brandenburg
  3. Conceptual model utilizing soil water isotopic compositions individually for the different land use types


  • Eddy covariance
  • Climatic measurements (air temperature, precipitation amount, wind speed/direction, solar radiation, rel. humidity etc.)
  • Soil moisture and temperature
  • Sap flux
  • Stem size variation
  • Leaf area index (LAI)
  • Precipitation, groundwater, and surface water stable water isotope sampling
  • Laboratory sampling and measurements of stable water isotopes
