Short summary
Using accurate elevation data, we generate coastal flooding maps for Norway. Although Norway is at low risk from sea level rise, parts of the coast are potentially vulnerable to flooding. Nationwide we identify an area of 400 km2, 105 000 buildings, and 510 km of roads that are at risk of flooding from a storm surge at present (these numbers increase to 610 km2, 137 000, and 1340 km with projected sea level rise to 2090). The maps aid coastal management and climate adaption in Norway.
