Sweden:
Northern Europe
2000 km long

12 thousand years ago ¨C Sweden was covered by 2000 m of ice.
The rock has rebounded by heave of almost 500 m!!
Sweden has the highest land uplift in the world.
Areas below highest sea
level ¨C geotechnical
problems:
Stability and settlements
Glacial Rivers created
Eskers
Rebound of ground
surface ¨C 1 to 10 mm/year
Most of Sweden covered
by till (moraine)
¡°Quick clay¡±
However, biggest problems in areas with soft clay
The Viking Period: 790 - 1100
Vikings built fortifications along sea shores and lakes
Landslide problems in soft clay
During construction of railway
lines around 1905 - 1920
