TRANSRISK (H2020-MSCA-IF-2016): Vulnerability and risk assessment of transport systems of assets exposed to geo-hazards

PI: Dr Stergios A Mitoulis  |  Marie-Curie Research Fellow: Dr Sotirios A Argyroudis

Industrial Partners: Norwegian Geotechnical Institute (NGI), TRL The Future of Transport


Challenge

  • Multiple hazards, e.g. flood series over time, flood-earthquake, earthquake-tsunami, are major threats to transport infrastructure (Figure 1)
  • Resilience-based management should include specific methods to define and measure resilience and new approaches for communicating assessments to stakeholders
  • Infrastructure owners and operators urgently need a methodology for enabling rapid risk and resilience assessments

Objectives

  • To deliver advanced numerical models of transport SoA subjected to critical geo- and climatic hazards
  • To develop fragility models for assessing the vulnerability of transport SoA exposed to multiple hazards
  • To establish resilience assessment models for transport infrastructure that account for the nature of the hazards, their sequence, the loss of functionality, the recovery strategies and their rapidity, and the associated losses
