Surface Waters -
Research & Management (Surf)

We focus both on processes in the aquatic environment as well as on entire systems of natural waters.

We perform basic and applied research and several projects have a problem-oriented and interdisciplinary focus, including system analysis. Read more

If the climate heats up, the temperature in the uppermost layer of lakes will increase, the thermic layering will become more stable and last longer, and less oxygen will reach the depths – this is the present theory on the effect of climate change on lakes. Read more

Research Projects

Wastewater is a source of antibiotic resistant bacteria. We study their dissemination in the aquatic environment, and strategies to remove them.
Lakes store large amounts of heat. To what extent can this heat be used to replace the use of fossil fuels or electricity for heating and cooling purposes?
We assess the environmental impacts of hydropower plants to support a sustainable development of this energy resource.
4’000 river kilometers will be rehabilitated in Switzerland over the course of the coming 80 years – a unique opportunity for learning!
