The first version published in 2018 was linked to the recommendations in DSB's guideline "Havnivåstigning og stormflo – samfunnssikkerhet i kommunal planlegging" from 201, with  storm surges and sea level change was based on the report Sea Level Change in Norway (2015), which was based on IPCC AR5. 

The dataset was updated in July 2024 according to the new dataset for "Storm surge and sea level". The background is the new guide for use in municipal planning from DSB, based on new knowledge from the report "Sea-Level Rise and Extremes in Norway" from April 2024, which is based on IPCC AR6. In addition to new time horizons, an upper estimat for high water levels have been added.

*This dataset has been temporarily removed pending updates. A new dataset is expected in the first half of July* 

The dataset contains statistics on buildings, areas and roads in your municipality that may be exposed to flooding from the sea for the situations described in the dataset "Storm surge and sea level".

The dataset "Storm surge and sea level" shows high water levels (storm surges) at today's sea level and at a future sea level. These are the levels DSB recommends the municipalities to use in its guide "Havnivåstigning og høye vannstander i samfunnsplanlegging" from 2024. The dataset also includes the coastal contour (mean high tide) today and at a future sea level. The allowances for future sea level change include land uplift.
