Hydrogeology is the science of groundwater and its interaction with rocks. In most parts of the world, groundwater is the quantitatively most important and qualitatively best drinking water resource. Hydrogeology deals with the occurrence, movement, quality, use and protection of groundwater. Our hydrogeological research includes observations, measurements and experiments in nature and in the laboratory as well as mathematical and numerical modelling. We cover the entire spectrum of groundwater research. Special focus is on karst and alpine hydrogeology, groundwater protection and management, tracer & pumping tests, artificial intelligence & machine learning, groundwater & ecology as well as thermal groundwater use.


We are involved in many ways in the Fachsektion Hydrogeologie e.V., an interdisciplinary interest group from science, authorities and industry that deals with all aspects of hydrogeology.



Prof. Dr Nico Goldscheider was appointed Honorary Fellow of the Geological Society of America (GSA)

Prof Goldscheider was appointed an Honorary Member of the Geological Society of America (GSA) in 2024. This programme was established by the GSA Council in 1909 and since then one or more honorary members have been appointed each year (with the exception of a few war years). Honorary members are international geoscientists who have made outstanding contributions to science through geoscientific research, the promotion of environmental awareness, the linking of science and society, remarkable achievements in the implementation of public policy in the field of natural resource management, or who have made outstanding contributions to science in other ways.

Cooperation and Solidarity with Israel

We have been cooperating with colleagues from Israel for many years and declare our full solidarity with our friends in Israel in this terrible situation. We therefore support the statement on the situation in Israel that KIT published as part of the Alliance of Science Organizations.

To the Statement
Contribution to the TV show Terra X: The Path of the Water

On 20.08.2023, the ZDF show "Terra X" dealt with the question of the origin and importance of water as a resource. Among other things, the tracer marking experiments carried out by the KIT in the Blautopf cave system on the Swabian Alb were featured (from minute 15:50).

Zur Sendung
TV report on the issue of groundwater extraction

The TV station SWR has also published an article focusing on increasing groundwater extraction as a result of climate change. The article gets to the bottom of the question of how much various user groups want to extract today today and in the future, and how this may be campatible with sustainability.

SWR2 interview with Prof. Goldscheider on current water shortage problems

The radio station SWR2 published a podcast on the (ground-)water shortage in Germany due to climate change. In a detailed interview with Prof. Nico Goldscheider, upcoming problems for water supply, regional challenges and individually implementable mitigation measures are addressed. (audio, 8 min.)

SPIEGEL-Titelgeschichte über Wassermangel in Deutschland

The current cover story of the SPIEGEL (30/2023) is about water shortages in Germany. Prof. Nico Goldscheider is quoted several times in connection with our cooperation with the state water supply in Langenau, which supplies 3 million people with drinking water, as well as with general statements about groundwater, water availability and the nitrate problem.

Dr. Andreas Wunsch erhält den Hermann-Billing-Preis

Dr. Andreas Wunsch receives the Hermann-Billing-Prize for his dissertation on "Leveraging Artificial Neural Networks for Modeling Hydrogeological Time Series". The award is confered at KIT since 1985 for outstanding doctoral theses and commemorates the Karlsruhe architect and university teacher Hermann Billing (1867–1946). On the occasion of the award ceremony, a public ceremony will take place on Wednesday, May 10, 2023 at 6:00 p.m. in the Egon Eiermann lecture hall of the Faculty of Architecture at KIT.

Podcast über Brunnen

A podcast about fountains was published in the radio series "Radiowissen" of the Bayerischer Rundfunk. Initially, the focus is on archaeological and historical aspects, but from minute 13:36 onwards the focus switches to hydrogeological questions, with contributions by Prof. Dr. Nico Goldscheider and three other colleagues from a well construction company and our partners from the Bundesanstalt für Geowissenschaften und Rohstoffe (BGR).
