In the years 2011 and 2013 two major debris flow incidents happened in Kollobekken, triggered by the combination of melting snow and heavy rain. Several houses where severely damaged by debris freight and water flooding and spreading across the settlements.


In March 2015 the NVE and the community decided to install a flexibke debris flow protection system type VX080-H4 to prevent future damages and protect the village. To avoid torrent erosion below the barrier, the mitigation measure was combined with plastering of the river sides and guiding the Kollobekken river through the settlement.
