NAWA-Fracht - National monitoring programme for substance load in swiss watercourses (2025-1)

There is an older version of this dataset.

The “National monitoring programme for substance load in swiss watercourses” (NAWA-Fracht, formerly known as NADUF) program was initiated in 1972 as a cooperative project between three institutes:

The following institutes participated later:

With the NAWA-Fracht 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 NAWA-Fracht network serves as a basic data and sampling facility to evaluate the effectiveness of water protection measures and for various scientific projects.

Data from 2021 to 2024

The physical data for the years 2021 and 2024 are provisional. Accordingly, the chemical data are not yet definitive.
