Teaching and research in hydraulic engineering represents for me an important pillar of civil and environmental engineering. Along with the changes in socio-political and environmental goals and the underlying ecological demands on our cultural landscapes, hydraulic engineering is undergoing a paradigm shift: in both utility and protective hydraulic engineering, it is essential to take water ecology concerns into account centrally in planning and projects,

This requires a wide-ranging education in hydraulic engineering, from the basics of hydromechanics and hydraulics to structural hydraulic engineering and near-natural watercourse development, nature-compatible flood protection and ecologically compatible hydropower utilisation. My motivation as head of department is to lead and accompany this training.

Today, the transdisciplinary intersection of engineering and natural science approaches results in complex and specialized design and planning specifications for the practicing hydraulic engineer, which are formed from physically correct, empirical and/or statistical formula bases and whose application always leads to target-oriented results only with appropriate experience. Within the framework of my teaching, I would like to convey these methods and their areas of application to prospective hydraulic engineers and encourage the exploration of existing gaps.

The Department of Hydraulic Engineering is therefore dedicated to the education of young hydraulic engineers. In addition to an extensive range of courses, current research tasks are also being worked on within the framework of ongoing doctoral theses, both in the basic area and in practical engineering applications.
