Much of the existing assessments of climate change impacts are large-scale simulations. Small- and local-scale assessments are necessary for nuanced understanding of possible impacts of multiple hazards on society. This view is needed for supporting local adaptation strategy and planning. At the same time, societies’ dependency on critical infrastructure and vital societal services is increasing, due to growing system complexity and interconnectedness. Together, these shifts are likely to increase societal vulnerability and impact adaptive capacity.

In response to this need, HydroHazards zooms into the municipality of Halmstad to explore the likelihood of multiple hydrometeorological (i.e., water and weather) events occurring sequentially or in the same location. Furthermore, we investigate the effects that climate change may have on the intensity and frequency of multiple hazards by focusing on extreme – low likelihood but high impact – events. Lastly, we look at the cascading or so-called domino effects on critical infrastructures and vital societal services and how these effects may cause new social vulnerabilities.
