“Its not in our backyard” problems dramatically disproved by climate change
Medicane Ianos – the Mediterranean Hurricane said to be formed due to climate change – has very recently caused extensive damage and devastation in Greece. To date, we had very little information regarding the intensity of this unprecedented natural disaster that was manifested with sequential flash floods having a knock-on effect on the regional infrastructure leading to the devastation of vulnerable communities.
And like as if this was not enough, a few months later an earthquke stroke the same area to bitterly prove that multihazard natural disasters are there to stay, agonise people and mock scientific models.
When I was writing a paper one year before, in 2020, on multihazard resilience of infrastructure (see https://lnkd.in/dCpzTBX7) in the Science of Total Environment I was thinking “a flood and an earthquake – this is a very unlikely scenario – not in our backyard” but I was terribly wrong! This happened one year later and very limited access was possible to the devastated area, due to another -health this time- hazard COVID19, with draconian travel restrictions.
Perhaps if it wasn’t for Marianna Loli, the paper “Flood characterization based on forensic analysis of bridge collapse using UAV reconnaissance and CFD simulations”
would have never been published and we would have just witnessed this disaster without knowing “why this happened”. But it takes an engineer with perseverance, a forensic investigation, emerging technology (UAV-photogrammetry), and advanced engineering modelling to find out the cause of such a catastrophe. And if this happens again, we have pointclouds of the critical assets to swiftly make decisions and reinstate the functionality of the infrastructure but -most importantly- help the local communities to bounce back normality and make them feel safer and happier.

New paper on climate resilience of critical infrastructure incentivised by digital technologies and data
In our agenda-setting paper that is just published in the journal of Climate Risk Management we argue that:
“Digital technologies can enhance climate resilience of critical infrastructure”
to boost economic growth and societal well-being for achieving the United Nations Sustainable Development Goals (sdgs2030). Deployment of emerging digital technologies, underpinned by multi-stakeholder alliances, is essential for accelerating progress toward more resilient infrastructure to contain and recover from multiple hazards in a sustainable manner.

Data-driven decision making with coupled engineering, satellite imagery and digital twining
To combat adverse and changing environments and deliver robust and well-informed resilience frameworks, aware of the impacts of climate change on our critical infrastructure we need to embrace digital data, forensics and evidence from engineering inspections and openly available data and evidence from satellite imagery (see e.g. Copernicus Open Access hub) and other emerging digital technologies. Our paper that was accepted today by the International Journal of Remote Sensing puts forward a novel #hybrid approach for assessing the condition of the landmark 46-year old Polyfytos Bridge in Kozani, Greece, using SAR Interferometry coupled with engineering data and forensics. For the first time in the international literature, satellite imagery was used to complement former #UAV-enabled digital twins of the bridge and interpret spatiotemporally variable deflections of the important asset. A data-driven decision-making approach is put forward toward measures to protect the asset, people and the local communities. The significance of this hybrid approach is that whilst UAV-point clouds provided a snapshot of the structure today, satellite data provided equally important insights by giving us the evolution of the deflections of the asset throughout the years, which added further intelligence to the engineers to identify the causes of the deflections.

Mini-Symposium has been announced in the IABMAS 2022, Barcelona conference
Delivering bridges resilient to multiple natural hazards and climate change is fundamental to continued economic prosperity and social coherence. Emerging and disruptive digital technologies have the potential to enhance the climate resilience of critical infrastructure such as bridges. Nevertheless, the potential of these technologies remains largely unexploited. This Mini-Symposium will show how emerging digital technologies, data and evidence will lead to more resilient bridges, by delivering efficient and reliable decision-making, in a proactive and/or reactive manner. We welcome papers in the areas of structural health monitoring, including terrestrial and airborne systems, digital data and digital twins; data integration platforms and tools (e.g. crowdsourced data, IoT, AI) used for the purpose of bridge resilience and sustainability. With this collection of papers, we aim to promote the exchange of knowledge concerning the latest research developments and practices of digital technologies, with a focus on bridges resilience and sustainability.

Our new paper titled “Innovations in earthquake risk reduction for resilience: recent advances and challenges
Our paper is now published in the International Journal of Disaster Risk Reduction
The Sendai Framework for Disaster Risk Reduction 2015-2030 (SFDRR) highlights the importance of scientific research, supporting the ‘availability and application of science and technology to decision making’ in disaster risk reduction (DRR). This paper summarises some of the key aspects identified and discussed during the workshop to inform other researchers worldwide and extend the conversation to a broader audience, with the ultimate aim of driving change in how seismic risk is quantified and mitigated. Read the paper here.

New paper “Restoration models of flood resilient bridges: survey data”
The data of our elicitation survey on restoration of flood damaged bridges is now available on-line in Data in Brief, please see here
The survey includes the duration and sequence of restoration tasks, idle times, cost, and traffic/functionality loss for specified damage levels of given bridge components. The use of this data is the generation of sets of restoration and reinstatements functions for quantifying the resilience of bridges exposed to hydraulic hazards, i.e. scour, debris accumulation and hydraulic forces, see here
New paper on “Restoration models for quantifying flood resilience of bridges”
In order to assess and quantify the resilience of flood-critical bridges and subsequently deploy bridge resilience models aiming at building resilience into transport networks, it is essential to use reliable fragility, capacity restoration and traffic reinstatement metrics and models.
In our recent paper “Restoration models for quantifying flood resilience of bridges” published in Engineering Structures, recovery models are presented, including restoration task prioritisation and scheduling, inter-task dependencies, idle times, durations and cost ratios for different damage levels, as well as the evolution of traffic capacity after floods.
The paper is authored by Dr Stergios Aristoteles Mitoulis, Dr Sotirios Argyroudis, Dr Marianna Loli & Dr Boulent Imam and is available here.
