Climate change scenarios are needed for flood mapping and risk response planning.

Currently, this kind of climate change and flood modelling is done only in the city of Pori and experiences and best practise from there are used also in Rovaniemi and Kittilä.

The local adaptation strategy themes, for example tourism and flooding, in WP3 are taken into account in this demonstration project.
