installed to continuously log the soil temperature.
Manual drillings were made to obtain soil samples for
index testing. (Further details and visual aids under

How to Make Sustainable Erosion
Protection Systems in the Arctic?
Considering the critical geotechnical conditions of some
Arctic coastal and riverside areas and the rising attention
on the impact of climate change in vulnerable regions,
the need for innovative, sustainable and environmentally
friendly construction methods for erosion protection is
becoming an issue of increasing interest. Construction
solutions become an even more challenging topic when
considering erosion protection in geographical areas
where no armor rocks or concrete blocks are easily
available. Soil improvement and innovative materials
used together with local soils are therefore a promis­
ing solution. For instance, geosynthetic tubes and bags

using local soil as filling material have been developed
and are now used in some test projects in Svea (Fig. 42).
The behaviour and durability of these structures were
monitored continuously during 2012.
