Week 13 : Coastal Hazards

     This week, I will be focusing on the extreme coastal erosion and how it is a major concern and a problem for Norway and its rising sea levels. Coastal erosion is a global issue but deeply effects the Arctic, as the soil is frozen and results in erosion that is three to four times more rapid than in warmer regions. Norway’s coastline is classified as emergent and is caused from a fall of sea levels and with the association of high cliffs in the case of Norway. The rates in which erosion occurs range from 0.5mm to 12.5 mm annually. This might not be so impactful as in other locations in the world, but many small towns in Norway reside on cliffs that are eroding and are at risk of losing these historical places.

     Norway has a way to adapt themselves to their vulnerabilities when experiencing coastal erosion. The first strategy that has been proposed is to strengthen the coastline by returning a balance to the sediment and creating a space that can aid natural erosion. A sediment reservoir that is large enough to restore the coastlines to the most effected areas can reduce the loss of landmass and in the long years ahead, protect the coastlines for a longer period of time. What helps this country is solifluction, the gradual movement of wet soil that travels down a slope and onto the coast. Because it is found nearly everywhere near the coast. The sediments move downward and create its own activated layer that forms on the coastline. With the warming of the climate, solifluction occurs more effectively and creates additional width on the shorelines!

  1. Hi Jonathan, for some reason I assumed that the Arctic wouldn't have a problem with erosion. I imagined it being frozen and stagnant. Thank you for sharing your research.
