Abstract

Mange sandstrande rundt om i verden mister sand på grund af erosion, og Nørlev Strand på Danmarks vestkyst er ingen undtagelse. Denne afhandling udvikler en model, der beskriver klimaet ved Nørlev Strand og kan bruges til at vurdere fortidige, nutidige og fremtidige klimaforhold. Under arbejdet blev der identificeret væsentlige klimatiske og morfologiske ændringer – det vil sige ændringer i kystens og havbundens form – som peges på som en hovedårsag til den accelererende stranderosion. Især ses en stigning i stormintensiteten i perioden 1999–2012. Klimamodellen kan let tilpasses det lokale klima ved Nørlev Strand og giver meget gode resultater, når den bruges til at estimere nettosedimenttransporten, altså den samlede bevægelse af sand langs kysten, som er central for at forstå erosionen.

Many sandy beaches worldwide are losing sand due to erosion, and Nørlev Strand on the west coast of Denmark is no exception. This thesis develops a model to describe the local climate at Nørlev Strand and to assess past, present, and future climatic conditions. The study identifies significant climatic and morphological changes—meaning changes in the shape of the coastline and seabed—as a main driver of the accelerated beach erosion. In particular, storm intensity increased between 1999 and 2012. The climate model can be readily adapted to the local conditions at Nørlev Strand and provides very good results when estimating net sediment transport, that is, the overall movement of sand along the shore, which is key to understanding erosion.
