Theoretical Ecohydrology Lab | Institute of Geoecology

We use theoretical methods—conceptual, mathematical, and numerical models—to study ecohydrological processes in terrestrial systems. We are currently working on:

  • urban ecohydrological units
  • differential equations-based mathematical models and
  • their numerical solution

We teach courses on terrestrial ecohydrology in the Environmental Sciences, Civil Engineering, and Environmental Engineering graduate programmes.


We believe that the integration of Ecohydrology into Geoecology is essential for exploring the feedback between terrestrial ecosystems and the hydrological cycle. This includes the impact of changes in land use and land cover, as well as the effects of urbanisation and ecological disturbances on hydrological and ecological functions.

By incorporating geoecological perspectives, our research provides a more complete understanding of the relationship between terrestrial ecosystems, water, and human activities, with important implications for water management and biodiversity conservation in an increasingly urbanised world.

We consider ourselves as a bridge between the Institute of Geoecology and the Leichtweiß-Institute for Hydraulic Engineering and Water Resources at Technische Universität Braunschweig.
