Systems Analysis, Integrated Assessment and Modelling

In SIAM, we develop and apply models and formal techniques in order to understand, demonstrate, and predict the behavior of natural, technical, social and economical systems that pertain to water and other natural resources. Read more

A new catalogue and database of over 17,000 European river catchments facilitates the work of researchers in the field of hydrology. The EStreams project, carried out at Eawag, provides hydrological and meteorological data as well as information on the landscape of the river regions. The records go back up to 120 years.

Projects

Bridging the gap between data science and mechanistic modelling for a better understanding of community composition.
Heterogeneous data platform for operational modeling and forecasting of Swiss lakes in collaboration with the Swiss Data Science Center.
Deep Neural Networks (DNNs) have shown empirical performance but they are still nevertheless a black-box function modeling data
Scalable Bayesian inference framework for uncertainty quantification in stochastic models using thousands of processors in parallel at the Swiss Supercomputing Center and ETH Zurich.

SPUX - High performance environmental data science

Mechanistic modelling of the macroinvertebrate community composition in rivers.
We compare invasions in aquatic and terrestrial ecosystems primarily at large (national) spatial scales and among several higher-level taxa (insects, molluscs, crustaceans, all major vertebrate classes, and plants).
We use machine learning methods to predict the effects of chemicals on aquatic species.
Development of a semi-distributed hydrological model with a “flexible” approach. Testing and comparing of different model structures to combine modeling and experimenting into a learning process.
Exploring the use of machine learning techniques to uncover low-dimensional features within high-dimensional datasets, both simulated and observed
