Systems Analysis and Water Management


The group „Systems Analysis and Water Management“ contributes in the following areas to the development and improvement of methods and models for the analysis of aquatic systems and societal decision making:

Environmental Modelling and Systems Analysis Methodology

Development of techniques for model-based statistical inference of environmental systems that account for the need of using prior information, input and model structure uncertainty, and intrinsic stochasticity.
