CLIWAT- Adaptive and sustainable water management and protection of society and nature in an extreme climate

The CLIWAT project will apply groundwater and integrated hydrological models for assessment of the hydrological impacts of different climate scenarios with focus on water table fluctuations, river discharge, delineation of flood risk areas and saltwater intrusion. The hydrological scenario simulations will be based on output from existing climate models and geological and geophysical measurements and modelling of the subsurface partly conducted in the project.

The results from the project will be used to predict how future climate change will affect water quantity and quality, and hence societies and ecosystems in lowlands around the North Sea. CLIWAT will provide the needed data for development of adaptive measures and new standards for e.g. engineering of drainage and sewer systems, dikes, roads and buildings, and for quantitative and chemical status assessments of groundwater and the aquatic environment according to EU directives.

The CLIWAT project will initiate important transboundary cooperation and evaluation of the effect of different climate scenarios in the EU North Sea region and establish predictive modelling tools for future simulations. The project website is intended to provide easy access to simulation results in the form of maps and visualisations facilitating cooperation and with the aim of increasing the the public awareness and understanding about climate change effects.
