In October 2014, a 2-day heavy rainfall event on the western coast of Norway caused major floodings. Hundreds of residents in the valleys around Flam needed to be evacuated, leaving houses, buildings and infrastructure severely damaged.
Research project TWEX was established to investigate such events in a future warming climate. The research answers questions such as: are the events more intense and what possible impact can we expect?
To assess these questions, research software engineers of the eScience Center performed simulations with the EC-Earth climate model of future high-precipitation situations. These simulations were used to drive hydrological models simulating the overflowing rivers along the Norwegian coast.
As a result, realistic future flooding scenarios for various river catchments were created, which may serve as a useful tool in guiding local authorities with their measures to adapt to a changing climate.
