Project TWEX publishes paper (September 2020): The role of spatial and temporal model resolution in a flood event storyline approach in western Norway

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 Flåm 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? Find out more in this paper
