  • plans and coordinates the monitoring of surface water volume;
  • is responsible for the scientific evaluation, analysis and publication of hydrological data on surface water volume collected by the federal authorities, and for environmental reporting on this topic at national and international level;
  • provides basic groundwork on long-term changes in water supply and on extreme events such as high and low water levels for the purpose of flood prevention, water pollution control and water usage;
  • publishes information on the impact of climate change on waters;
  • compiles recommendations and guidelines for determining low water Q347 flow rates as a basis for quantitative water pollution control;
  • conducts hydrological surveys and research projects;
  • advises other federal agencies, the cantons and members of the public, and handles legislative affairs concerning surface water hydrology.
