> index : theoretical ecohydrology lab

In brief

The Theoretical Ecohydrology Lab at the Institute of Geoecology builds and applies tools for the process-based modelling of interactions and feedbacks among hydrology, ecology, and microclimate in terrestrial and urban systems.

Our research foci are:

  • soil–plant–atmosphere continua
  • ecohydrology in water-limited systems
  • isotope-aided ecohydrology

We are located on the 4th floor of the Institute of Geoecology, Technische Universität Braunschweig, Langer Kamp 19c, 38106 Brunswick, Germany.
