Coupled physical and geochemical modelling of lakes


We perform numerical simulations of coupled physical and geochemical processes in lakes. The aims of these modelling studies are

  • to estimate budgets, sources, sinks and residence times of substances, such as nutrients or dissolved gases, in lakes.
  • to assess the importance of specific geochemical processes in lakes and quantify the respective process rates.
  • to evaluate human impacts on lake physics and geochemistry, and support the development strategies for lake management under anthropogenic pressure.

As modelling tools, we use
