Karst research

 

 

Almost a quarter of the world population obtains its drinking water from karst systems. Our research focuses on the assessment of water resources in karst regions at various scales. We develop new modeling and parameter estimation procedures for more reliable karst water management under current and potential future conditions. Global monitoring programs and multivariate model evaluation help us to improve the reliability of our predictions of water availability.

Research beyond the karst

 

The strong experience in developing and evaluating hydrological models allows us to transfer our approaches to other hydrological environments. Hydrochemical signatures were used to improve the simulation of subsurface storm flow (SSF) at the catchment scale. Using a multivariate simulation of water levels and stable water isotopes, we could improve evapotranspiration simulations of a tropical wetland. Our large-scale approaches were also used in streamflow analysis.
