theoretical ecohydrology lab

> index / about : tee



We use theoretical methods—conceptual, mathematical, and numerical models—to study ecohydrological processes in terrestrial systems. We are currently interested in modelling water fluxes through the soil–plant–atmosphere system and their re-scaling to the catchment scale and applying systems theory to urban ecohydrology.

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

You can find us online at our official webpage, or in the real world on the 4th floor of the Institute of Geoecology at Langer Kamp 19c, 38106, Brunswick, Germany.
