Eawag - Swiss Federal Institute of Aquatic Science and Technology

Eawag is one of the world’s leading aquatic research institutes. With its professional diversity, close partnerships with practitioners and an international network, Eawag offers an excellent environment for the study of water as a habitat and resource, for identifying problems at an early stage and for developing widely accepted solutions.

Data-driven modelling of residual flows

February 24, 2026

Estimates as to how much more electricity could be generated from hydropower in the absence of residual flow requirements vary widely, and they have previously been based on inadequate data. A team of researchers from WSL, the University of Bern and Eawag has now used a new database and simulations to show that, between now and 2050, the additional decrease in production due to residual flow requirements – amounting to barely 2% – is likely to be much lower than feared.

Eawag Kastanienbaum, Seeheim

Eawag’s two sites are characterised by office and laboratory buildings as well as research facilities such as the experimental ponds in Dübendorf and the boathouse in Kastanienbaum. But if you look closely, you will discover works of art between the buildings, mostly created as “art in construction”. They offer creative insights into research and local history – and invite you to explore.

we are investigating the basis for clean drinking water and sustainable management of drinking water resources.

we are investigating how to optimise wastewater infrastructures and overcome new challenges.

our research contributes to understanding and conserving aquatic biodiversity.

we are investigating biotic communities and their habitats in order to conserve ecosystem services for us humans.

we are investigating the effect of chemical substances on the environment and developing methods to remove them from drinking water, wastewater and bodies of water.
