> 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.
