Chair of Environmental Hydrological Systems

Welcome to the homepage of the Chair of Environmental Hydrological Systems, Prof. Kerstin Stahl

We teach in the Bachelor programme "Environmental Sciences" and in the "Master of Hydrology" among others and participate in local, national and international science activities.

Our research deals with climate impacts on hydrology and water resources, in particular hydrological extremes and their impacts on environment and society. Projects that are keeping us busy focus on:

  • drought hazard and risk under global change (several projects)
  • hydrological processes and storages in catchments with
  • a focus on (partly glacierized ) mountain headwater regions (e.g. ASG Rhine project)

Here is the team


Kerstin Stahl
stahl Hydrologist studying water's links to climate, environment and society: empirically at large scale, regionally with models, preferably long-term and with a special passion for mountain hydrology and downstream impacts of drought.

Research and teaching staff

Carolin Winter
Hydrologist with a focus on catchment-scale water quality in the face of global change. I am particularly interested in the effects of changing hydro-meteorological conditions on water quality and in the insights into hydrological and biogeochemical processes that we can gain from high frequency monitoring. winter
Jost Hellwig
hellwig Hydrological modeller and data scientist studying groundwater and surface water availability and quality. Research focus is drought and the complex interaction of climate-, catchment- and anthropogenic processes as the main driver of regional differences in drought occurrence.

PhD students

Amelie Herzog
Hydrologist studying water availability in the different compartments of the critical zone. Research focuses on measurement and modeling of hydrological processes at catchment scale. Currently working on the link between drought, streamflow intermittency and anthropogenic impacts on water resources. herzog
Kathrin Szillat

Hydrologist, interested in hydrological extremes and their impact on the environment and society. Works in the project EDORA, which was launched by the European Commission (DG Environment and DG Joint Research Centre), aiming to improve drought resilience and adaptation throughout the EU.

Yonca Cavus
Civil engineer studying hydrology with a focus on droughts. Interested in drought analysis for water resources management at river basin scale. Works on drought reconceptualization and data-based drought intensity-duration-frequency curves using drought indices and physical variables, precipitation deficit and water deficit. cavus
