NADUF – National long-term surveillance of Swiss rivers

Sampling station Rheinsfelden at river Glatt

The “National Long-term Surveillance of Swiss Rivers” (NADUF) program was initiated in 1972 as a cooperative project between three institutes: the Federal Office for the Environment (BAFU), the Swiss Federal Institute of Aquatic Science and Technology (EAWAG) and since 2003 the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL).
With the NADUF program, the chemical-physical state of Swiss rivers as well as intermediate-term and long-term changes in concentration are observed. Furthermore, it provides data for scientific studies on biological, chemical and physical processes in river water. The NADUF network serves as a basic data and sampling facility to evaluate the effectiveness of water protection measures and for various scientific projects.
