Transport infrastructure is a pylon to our economies and social equity. However, it is disproportionately exposed and hit by multiple natural hazards, with floods being the main cause of their failures across the world. Their performance is continuously challenged by the combined effects of natural hazard stressors, e.g. flash floods, exacerbated by climate change, aggravated by ageing, increasing traffic volumes and loads. To assess and quantify the resilience of critical transport assets, e.g. bridges, and subsequently deploy resilience models for transport networks, it is essential to use reliable fragility, capacity restoration and traffic reinstatement metrics and models. It is surprising that despite the importance of transport networks, there is very limited information and even less available recovery models. The latter can assist in quantifying the pace of post-disaster capacity and functionality gain for facilitating well-informed decision making for reliable prioritisation and efficient allocation of resources in transport networks.
This special session was motivated by the need to bring together and establish an alliance between researchers, engineers, transport infrastructure operators and owners, including governmental bodies, (re)insurance companies, and policy makers. It aims at providing a platform for discussion and springboarding the development of practical, efficient and sufficient restoration models, in an effort to build resilience into our critical infrastructure. This session envisages obtaining valuable input by researchers, practitioners and stakeholders dealing with risk and resilience analysis and management of transport infrastructure to natural and climatic hazards. The participants can contribute with technical and opinion papers, and/or initiate or lead discussions. The participants will also be benefited by participating in and receiving results from elicitation questionnaires, which will be filled in the framework of this session. The following themes are encouraged, but not limited to:
- Restoration strategies (resourcefulness, rapidity, prioritization, decision making, tools, spatiotemporal dependencies, e.g. country-specific)
- Restoration modelling (structural capacity) for individual and multiple hazards
- Reinstatement of functionality and operability (traffic capacity)
- Proactive and reactive climate adaptation
- Lessons learnt from previous disasters and case studies
- Digital technologies and monitoring systems in multihazard resilience
- Legislation and guidelines in design and assessment
This session is intended as the second part of a pair of sessions. The companion session will focus on “Flood risk for bridges and transport networks: monitoring, modelling, and assessment”.
