InfraRisk is concerned with the occurrence of extreme weather events (EWE) and the related threats to infrastructure in Norway.

and the related threats to infrastructure.

The project 'Impacts of extreme weather events on infrastructure in Norway' (InfraRisk) is a three year project (2010-2013) and part of the NORKLIMA-programme, a 10-year programme (2004-2013) funded by The Research Council of Norway (RCN) which deals with 'Climate change and impacts in Norway'. The project will be operated in close collaboration with several research institutes and different end-users.


InfraRisk will focus on a range of questions concerning the impact of extreme weather events (EWEs) on the Norwegian transportation infrastructure.

About infrarisk

Currently we have limited systematic knowledge about which EWEs affect the Norwegian infrastructure adversely, the climatic parameters that control these events and their spatial and temporal distribution. Furthermore there are large gaps in our mapping of natural hazards that can be related to EWEs.

An assessment of the risk to our infrastructure from EWEs also requires identification of the different types of values infrastructure objects have to society and how these values may degrade in case of a given event. Lastly there is a need to investigate whether the relevant decision making systems are able to convert an improved knowledge about the risk from EWEs into effective adaptation.

In order to address these needs the InfraRisk project will aim to meet the following objectives:

  • To gain a more solidified understanding of how changing climate affects the frequency, intensity and distribution patterns of EWEs in Norway
  • To identify current knowledge about the impact of EWEs on infrastructure in Norway
  • To quantify the vulnerability and societal value of Norwegian infrastructure
  • To investigate which mitigation measures that could be implemented in order to more effectively adapt to these types of events
  • To develop a methodological framework for assessment of the total risk to infrastructure from the combination of EWE's
  • To propose guidelines for pro-active behaviour with regard to mitigation actions against climate induced natural hazards.

Project organization

InfraRisk is organized around open questions and needs with regard to mitigation of risks posed by EWEs to road and railway networks. A comprehensive risk assessment will be performed by several research institutes focusing the natural and socio-economical impacts of EWEs on the transportation infrastructure.

The risk assessment will be carried out by the four research institutes Norwegian Meteorological Institute (met.no), Norwegian Geotechnical Institute (NGI) inclusive International Centre for Geohazards (ICG), Centre for International Climate and Environmental Research (CICERO) and Institute of Transport Economy (TØI), which will cooperate intensively.

Throughout the project the relevant research needs and focus areas will be identified in consultation with the project end-users Statens Vegvesen (SVV) and Jernbaneverket (JBV) and in close contact with the National Emergency Planning Colleague (nusb). Such a comprehensive project structure will give great opportunities to work within an interdisciplinary and applied framework. On each stage there will be an intensive exchange of knowledge and experiences between all project partners (especially with the end-users and decision-makers).

The project work will be separated in four modules. Module A, B and C address the different steps of a comprehensive risk assessment whereas Module D represents a concluding module which will outline a management strategy for optimal adaptation to the risk resulting from EWEs. This includes an overview of the information that is needed in order to enable risk assessment, the available mitigative options for risk reduction and the factors that may constrain the decision makers ability to adapt effectively. It also includes an assessment of the uncertainties involved on all levels.

NGI - Norwegian Geotechnical Institute is a leading international centre for research and consulting in the geosciences. NGI develops optimum solutions for society, and offers expertise on the behaviour of soil, rock and snow and their interaction with the natural and built environment.


The International Centre for Geohazards (ICG) carries out research on the assessment, prevention and mitigation of geohazards, including risk of landslide in soil and rock due to rainfall, flooding, earthquakes and human intervention, and the geological risks in deep waters, especially underwater slides. The Centre also contributes to the education of researchers and specialists in these Fields.


The Norwegian Meterological Institute provides the public with meteorological services for both civil and military purposes. The institute is to provide services for the authorities, commerce and industry, institutions and the general public for the protection of their interests, for the protection of life and property, for planning and for the protection of the environment.


CICERO is an independent research center associated with the University of Oslo. CICERO conducts research on and provides information and expert advice about national and international issues related to climate change and climate policy.


The Institute of Transport Economics carry out applied researchon issues related to transport and to promote the application of research results by advising government authorities, the transport industry and the public at large. Its sphere of activity includes most of the current issues in road, rail, sea and air transport, as well as urban mobility, environmental sustainability, and road safety.


National Emergency Planning College is organised under The Directorate for Civil Protection and Emergency Planning (DSB). The principal aim of the college is to train all categories of personnel in emergency planning and crisis management within the context of a Total Defence strategy.


Jernbaneverket (the Norwegian National Rail Administration) is the national railway authority. Jernbaneverket is responsible for the management of the national railway network, on behalf of the Ministry of Transport and Communication.


The Norwegian Public Roads Administration is responsible for the planning, construction and operation of the national and county road networks, vehicle inspection and requirements, driver training and licensing.


  • InfraRisk Final Report
    At least 27 per cent of Norwegian roads and 31 per cent of trhe Railway net is exposed to snow Avalanches and rock falls. Closed roads as a result of slides and avalancheshas a cost of at least 100mill. NOK per year. This is is revealed in the InfraRisk report which was published 13th December 2013 by the four research institutes; NGI - Norwegian Geotechnical Institute, inclusive International Centre for Geohazards (ICG), Norwegian Meteorological Institute (met.no), Centre for International Climate and Environmental Research (CICERO) and Institute of Transport Economy (TØI).
