Modelling of aquatic populations and ecosystems

Computer-based mechanistic simulation models play an increasingly important role in environmental risk analysis and environmental management.

For example, dynamic water quality models are increasingly regarded as useful decision-making tools in integrated water management and efficient implementation of the EU Water Framework Directive. In addition, the use of effect models which can adequately represent the impact of pesticides on populations or communities is gaining acceptance in the ecotoxicological risk assessment.

The following modelling approaches are currently in use at gaiac:

Aquatic ecosystem models for standing waters

Development of individual-based population models (IBMs)

  • IDamP: Water flea (Daphnia magna) population model (Dr. T. Preuss, RWTH Aachen University)
