Hydrological climate change impact scenarios: developing the tools for a new generation.

HYDROIMPACTS2.0 is a strategic research project on climate change impact funded by the Swedish Research Council Formas. It is a joint project with researchers from Lund University, Luleå University of Technology and SMHI. The hydrological research unit at SMHI is coordinating the project.

Climate change will affect hydrological processes at different scales in time and space. To define and quantify the impact in society, a large variety of hydrological impact studies are performed by many actors. Such effect studies play a key role for analysis and planning within a range of fundamental societal functions, for instance water and energy supply, city planning, security and environment.
A critical task in the analysis chain is to link results from global and regional climate models to hydrological models. At present, effect studies are limited by different properties of today´s climate models, such as the low spatial resolution and various systematical errors and uncertainties.

HYDOIMPACTS2.0 will provide a new generation of hydrological climate change impact studies by:

  • developing methodology for improving the link between Regional Climate Models and hydrological assessments in effect studies of different characters and scales
  • quantifying the magnitude of the improvements for a variety of hydrological processes
  • formulating guidelines for optimal prodecures in specific types of effect studies, with respect to scientific soundness as well as cost-effectiveness
  • illustrating the usefulness of the new methods in pilot sites for assessments focused on e.g. flooding, pollutant leaching, nutrient transport and shift in hydrological regimes
  • quantifying and mapping climate change effects on the fresh-water hydrosphere in Sweden and Europe


Results will be distributed through scientific publication and a database on the internet with free access for visualisation and downloading. The figure below illustrates the contents of and coupling between the work packages.
