Modelling

Modelling is an essential tool of environmental research. Models are used in our department to analyse data from laboratory and field experiments. Thereby the main goal is to test whether our conceptual understanding agrees with real observations. We also make use of models to make quantitative prediction of the occurrence of organic molecules in aquatic ecosystems. The models and simulation tools may differ substantially according to the actual purpose. They range from tools to describe sorption properties of a molecule based on its chemical structure, over relatively simple multi-media models used for risk analysis for a large number of chemicals and their transformation products and to GIS-based hydrologic models to identify risk areas in catchments.
