Limited water resources and increasing vulnerability are among the key challenges facing humanity. 

These pressures stem especially from the utilisation of natural resources and the degradation and contamination of the environment. In most areas, water problems are closely connected to political and societal systems. For one, unstable conditions and the short-term planning of societies cannot support the sustainability of water resources. Meanwhile, conflicts of interest related to water sow discord even between nations. 

The aims and scope of the research group are to:

• study global water challenges with a problem-solving approach, taking into account the multifaceted relationships between water and development
• offer high-quality teaching related to the research topics
• provide expert services related water issues and sustainable technologies

In this area, the main topics of our work are:

• Water for food
• Climate change and water
• Integrated approaches to water management: IWRM, water-energy-food nexus
• Transboundary rivers; role of power and politics in water management
• Water innovations & water business

As water is both a vital resource as well as a resource that is exposed to environmental effects, human society is inextricably connected to and reliant on nature and its waters.

The aims and scope of the research group are to:

• promote sustainable use of water and advance the assessment and prediction of the state of the water environment
• measure and quantify changes in water and the water environment caused by anthropogenic activities in both empirical and laboratory settings
• develop computational hydrology and hydraulics applications, ecohydraulics, nature-based solutions and basin-scale process examination – the watershed basin is our key unit, enabling the study of the effects of land cover and sub-processes related to precipitation, evapotranspiration, water storage and runoff development 

In this area, the main topics of our work are:

• ecohydraulics and nature-based solutions
• water in cities
• water in agricultural areas
• water in forests

Water and wastewater engineering research covers drinking water production, wastewater treatment and the piped networks needed for water supply and sewer collection. Providing water services is critical for society: they need to be functional on every day and under every circumstance.

The aims and scope of the group are to:

• improve the performance of drinking water and wastewater treatment processes in terms of resource recovery, automation and control, as well as the removal efficiency of conventional and emerging pollutants
• support the optimal management of drinking water distribution and sewer collection systems using existing operational and geospatial information – our research is supported by an analytical water laboratory and a variety of on-site measurement and treatment devices
• support water utilities by improving cost efficiency, reducing environmental loads and producing safer drinking water – these solutions often have business potential for the companies involved

In this area, the main topics of our work are

• preventive health care: clean water production and sanitation
• environmental protection: wastewater treatment processes
• energy and resource efficiency: water supply and sewer systems; nutrient and metal recovery from wastewater; sludge utilisation
