The research group Hydrogeology tackles the pressing regional and increasingly global challenges which affect groundwater and its protection as a natural resource. Scientific studies into the preliminary and follow-up protection of groundwater always take social and economic aspects into account. The group's regional activities include aspects of prealpine and alpine hydrogeology, global change, groundwater and surface water interactions, the passive and semi-passive remediation of large aquifers and the problems of groundwater in urban areas. Since the supply of drinking water will be one of the world's biggest challenges in the 21st century, the group also develops strategies for sustainable water supply in arid/semiarid areas and megacities. In this respect, an additional main focus of our work are investigations of groundwater quantity and quality changes due to revitalization of rivers.
Eawag and in particular the Department Water Resources and Drinking Water (W+T) is actively participating in the PhD School Water Earth Systems (WES). The aim of the PhD school is to provide a stimulating research environment for students working on the water-related topics in various earth systems.

In the framework of the RECORD Catchment project, we installed webcams at our study site in Niederneunforn/Altikon at a restored river section of the river Thur in 2016/17. If you are interested in getting some pictures please contact: Reto Britt
In the Groundwater App, in three short chapters you learn, how groundwater originates, how we use it and why there is a link to rivers. Furthermore you can do experiments in the groundwater lab. Here you can increase your knowledge about the behavior of groundwater.The application is available for free in the android and iOS appstores. The concept for this app was developed in the framework of the final thesis for becoming a Master of Arts in Design at the Zurich University of Arts (ZHdK), advised by the Eawag and financed by the Amt für Umwelt des Kanton Thurgau and the Swiss Gas and Water Industry Association. Target audience are adolescents from the age of 10 on. The app is available in English, German, French and Italian.
Large-scale alterations of the hydrological cycle have dramatically altered the natural runoff and recharge characteristic of many rivers, making the management, supply, and protection of freshwater resources a complex, albeit important topic. In order to develop catchment‐wide solutions for predicting water surplus and shortage, it is necessary to understand how the overall hydrogeological system works. Conceptualizing the physical and chemical balance between surface water and groundwater holistically is crucial for the sustainable utilization and management of freshwater resources. For this, data, models and real-time monitoring systems are the key ingredients in the process of understanding and prediction, and subsequent improved management
This SNF funded project is looking at water distribution within the Thur River catchment, Switzerland. The project focuses on the management and development of an existing data platform (RECORD Catchment, FOEN, and Cantonal) for water quality and quantity, and the development of adaptive and event-based monitoring schemes for water characteristics. In this project, some of the decisions on experimental design will be based on the results of model development with the objective of developing a semi-distributed model based on areas of hydrological similarity (Hydrological Response Units - HRUs) for the purpose of determining water balance on a supra-regional scale.
The INSPIRATION project aims to develop the tools and framework required for sustainable agricultural intensification and urban development in Europe. The project encompasses an innovative training network (ITN) consisting of 15 early-stage researcher (PhD positions) at various institutions in the UK, Ireland, Poland, Belgium, the Netherlands, Germany and Switzerland, as well as industrial and scientific expertise provided by a number of non-academic partner organizations. Declared targets of the program include the evaluation of technological innovations and methods to manage environmental impacts as well as the development and application of novel monitoring and prediction approaches.
In the course of this project, the Hydrogeology group (Dep. W+T) hosts two early-stage researchers tasked with the development of an adaptive monitoring scheme for a catchment in the canton of Zurich. The development and application of a low range wireless sensor network for target contaminants (Robin Weatherl) will be supported by, and feed into, the creation of a flow and reactive transport model (Maximilian Ramgraber). The information derived from this work should aid decision makers everywhere seeking to develop sustainable land use and water practices.
Assessment and Modeling of Coupled Ecological and Hydrological Dynamics in the Restored Corridor of a River
River restoration is an essential tool to achieve "good ecological status” of water courses as required by European and Swiss legislation. Although the number of restoration projects has increased in recent years, scientific understanding of the underlying principles determining how hydromorphological variability in restored corridors of rivers relates to
is still limited. Our objective is to increase mechanistic understanding of coupled hydrological and ecological processes in near-river corridors. For this purpose, we are
