Modelling the 180 kilometre Limfjord
Studying storm surges to prevent damage and protect lives
Following a severe storm in 1862, a breach at the present city of Thyborøn opened a new outlet to the sea for the 180 kilometre Limfjord in Northern Denmark. The new inlet developed rapidly, with the surrounding coast eroding by half a kilometre. Over the years, continued erosion in the Thyborøn Channel has led to increased flooding in the Limfjord. This puts cities situated around the fjord, with a total population of over 60,000 people, at risk. We used MIKE 21 to determine the correlation between erosion and storm surges, as well as the possible impact of climate change. We gave the Danish Costal Authority the tools needed to examine future problems involving flooding in the Limfjord and advised them on possible solutions.
