Stochastic Hydrology

The Stochastic Hydrology group develops innovative methods for modelling coupled hydrosystems considering uncertainties in the data, the model structure and parameters as well as system changes such as climate change and land use changes. In contrast to deterministic modelling, stochastic modelling yields probability functions of model outputs and state variables which allows to evaluate both the precision and the accuracy of predictive models.

The following modelling techniques are developed and applied in our group:

• inverse modelling techniques,
• ensemble modelling,
• model calibration methods,
• Pareto analysis,
• multiobjective optimisation as diagnostic tools for model deficiencies,
• MCMC simulation to determine parametric uncertainties,
• model simplification and surrogate modelling,
• data worth analysis and optimal design of monitoring networks, and
• Bayesian methods (calibration, model averaging, ...).

Applications comprise surface water - groundwater interaction, flow and contaminant transport in soil-plant-atmosphere systems, and hydrological modelling. here we also analyse scaling processes between the soil pedon scale, field scale to small catchments. The determination of hydraulic properties of soil samples and the analysis of stable water isotopes is conducted in our own lab which is part of the work group.
